Description

La présente invention concerne un ensemble portant à aile profilée (une telle aile profilée étant couramment dénommée « foil » dans la terminologie anglo-saxonne répandue, ou encore aile), pour des bateaux non propulsés par des voiles. Il peut s'agir par exemple de bateaux propulsés par moteur thermique, par énergie électrique, hydraulique, solaire, par hydrogène, par hydrojet, etc.The present invention relates to a supporting assembly with a profiled wing (such a profiled wing being commonly referred to as a “foil” in widespread Anglo-Saxon terminology, or also a wing), for boats not propelled by sails. These may be, for example, boats propelled by heat engine, by electric, hydraulic, solar, hydrogen, hydrojet, etc.

En particulier, l'invention s'applique aux bateaux semi rigides motorisés. Le « moteur » de ces bateaux peut être un moteur thermique, électrique, hydraulique, ou d'une autre nature. L'organe de propulsion de ce moteur peut être par exemple une hélice ou une turbine. Dans l'exemple qui sera détaillé dans cette demande il s'agit d'un moteur à hélice. De tels bateaux sont décrits par exemple dans JP S47 30493 U 6, US 3 810 268 A ou GB 2 091 646 A .In particular, the invention applies to motorized semi-rigid boats. The "engine" of these boats can be a heat engine, electric, hydraulic, or of another nature. The propulsion member of this engine may for example be a propeller or a turbine. In the example which will be detailed in this application, this is a propeller motor. Such boats are described for example in JP S47 30493 U 6, US 3,810,268 A Where GB 2 091 646 A .

Le concept de foil a été développé depuis des années pour des bateaux de types divers, et notamment pour des bateaux à voile.The foil concept has been developed for years for boats of various types, and in particular for sailing boats.

Dans ces développements, le bateau équipé d'un ou plusieurs foils immergés dans l'eau est destiné à flotter sur l'eau à l'arrêt ou à vitesse réduite (régime archimédien), comme un bateau sans foils.In these developments, the boat equipped with one or more foils submerged in water is intended to float on the water at a standstill or at reduced speed (Archimedean regime), like a boat without foils.

Lorsque le bateau avance sur l'eau (propulsé par des voiles, ou un autre type de propulsion) la partie du ou des foil(s) qui est immergée est orientée de manière à générer une portance dans l'eau. Cette portance se répercute sur le bateau qui est solidaire du ou des foil(s). Selon le point d'application de cette portance sur le foil, selon la position du foil par rapport au bateau et selon l'orientation de cette portance, cette portance peut être utilisée pour générer divers effets (par exemple : tendre à soulever le bateau au-dessus de l'eau, ou exercer sur le bateau un moment de redressement).When the boat advances on the water (propelled by sails, or another type of propulsion) the part of the foil (s) which is submerged is oriented so as to generate lift in the water. This lift is reflected on the boat which is attached to the foil (s). Depending on the point of application of this lift on the foil, according to the position of the foil in relation to the boat and according to the orientation of this lift, this lift can be used to generate various effects (for example: tend to lift the boat upwards). above the water, or exercise a moment of righting on the boat).

Dans le cas des bateaux à voile, les foils sont typiquement utilisés pour contrer la gite du bateau sous voile, et tendre ainsi à le redresser. De manière plus marginale, les foils sur bateaux à voile peuvent être utilisés pour tendre dans une certaine mesure à soulever le bateau, de manière à diminuer sa surface mouillée (c'est à dire sa surface de coque qui est immergée).In the case of sailing boats, foils are typically used to counter the heel of the boat under sail, and thus tend to straighten it. More marginally, foils on sailing boats can be used to tension to a certain extent to lift the boat, so as to decrease its wetted surface (ie its hull surface which is submerged).

Dans tous les cas, les foils de bateaux à voile, lorsqu'ils sont disposés par paires (généralement une seule paire) de part et d'autre de l'axe longitudinal du bateau, ne sont utilisés que partiellement : seul le foil situé sous le vent du bateau gité « travaille » réellement, l'autre foil n'étant pas utile, voire ayant des effets nuisibles à la bonne marche du bateau car se trouvant immergé avec une orientation non désirée mais résultant de l'implantation du foil sur le bateau.In all cases, the foils of sailing boats, when they are arranged in pairs (generally a single pair) on either side of the longitudinal axis of the boat, are only partially used: only the foil located under the wind of the heeling boat really "works", the other foil not being useful, even having harmful effects on the good running of the boat because being submerged with an unwanted orientation but resulting from the installation of the foil on the boat.

Pour éviter de tels effets nuisibles on a imaginé des foils escamotables au travers de la coque du bateau. On connaît ainsi depuis peu des bateaux à voile dont les foils situés respectivement à bâbord et tribord du bateau, sont escamotables à volonté et indépendamment l'un de l'autre. De la sorte, quand le bateau est gité (ce qui est le cas lorsque le bateau avance, et qu'on cherche à utiliser ses foils) on déploie le foil sous le vent hors de la coque du bateau (ainsi ce foil sous le vent est pleinement immergé, et actif hydrodynamiquement en générant de la portance), tandis qu'on escamote au travers de la coque du bateau le foil situé de l'autre côté du bateau, au vent du bateau (de la sorte ce foil au vent n'est pas ou que très peu immergé, et ses éventuels effets hydrodynamiques indésirables sont évités).To avoid such harmful effects, retractable foils have been devised through the hull of the boat. Sailing boats have thus recently been known in which the foils located respectively on the port and starboard side of the boat, can be retracted at will and independently of one another. In this way, when the boat is heeled (which is the case when the boat is moving forward, and we are trying to use its foils) we deploy the foil downwind out of the hull of the boat (thus this foil downwind is fully submerged, and hydrodynamically active by generating lift), while the foil located on the other side of the boat is retracted through the hull of the boat, upwind of the boat (so this upwind foil doesn is not or only very little submerged, and its possible undesirable hydrodynamic effects are avoided).

Ces bateaux à voile connaissent actuellement un développement important. Avec ces bateaux les foils sont donc utilisés en alternance (de manière à ce que seul le foil sous le vent travaille), et de récents développements ont donné accès à des foils escamotables pour cette utilisation en alternance.These sailing boats are currently experiencing significant development. With these boats, the foils are therefore used alternately (so that only the leeward foil works), and recent developments have provided access to retractable foils for this alternating use.

Dans le cas des bateaux à moteurs, l'utilisation des foils est sensiblement différente, puisque ces bateaux ne sont pas conçus pour naviguer en position gitée. Au contraire, ces bateaux à moteur doivent naviguer « à plat » sur l'eau, sans giter.In the case of motor boats, the use of foils is noticeably different, since these boats are not designed to sail in a heeled position. On the contrary, these motor boats must sail "flat" on the water, without heeling.

L'invention dont il est question ici concerne les bateaux à moteur, et plus particulièrement les bateaux de type semi rigides.The invention in question here relates to motor boats, and more particularly to semi-rigid type boats.

Les bateaux semi rigides sont un type de bateau motorisés bien connus qui comprennent une coque rigide et des boudins de protection latéraux gonflables. Ces bateaux ne sont pas aujourd'hui équipés de foils. La raison est que cette intégration de foil sur des bateaux motorisés semi-rigides pose de nombreux problèmes, qui sont liés notamment au dimensionnement et à l'intégration des foils dans le bateau, aux structures de bateau qui doivent supporter des efforts liés aux foils qui sont importants et qui sont répartis différemment de ce qu'on connaît des efforts appliqués à des semi rigides sans foils, et l'encombrement de l'installation qui pourrait empiéter notamment sur le volume intérieur habitable (par ailleurs réduit), dans le respect des conditions de sécurité et des normes du secteur. Le problème est particulièrement vif pour l'adaptation de foils sur un bateau semi rigide qui répond à des contraintes d'utilisation très spécifiques qui sont différentes de celles des bateaux à voile ou des bateaux à moteur. Un autre problème qui se pose avec l'intégration de structures portantes à aile portante sur des bateaux semi rigides motorisés est la nature particulière du bateau semi rigide qui est utilisé dans une application dite de beaching en langage professionnel communément adopté, à savoir d'accostage sur la plage. L'avantage d'un semi rigide étant sa souplesse d'utilisation, sa légèreté, pour aborder des lieux difficiles et des plans d'eau ou la profondeur est faible voire nulle en cas d'accostage. Par ailleurs et de manière fondamentale vis-à-vis des voiliers à foils, les structures portantes doivent être adaptées aux caractéristiques de navigation propres au semi-rigide, qui navigue notamment sans gite, à l'inverse d'un bateau à voile (et notamment des bateaux à voile munis de foils).Semi-rigid boats are a well-known type of motorized boat that include a rigid hull and inflatable side protection tubes. These boats are not today equipped with foils. The reason is that this integration of foils on semi-rigid motorized boats poses many problems, which are linked in particular to the sizing and integration of the foils in the boat, to the boat structures which must withstand the forces linked to the foils which are important and which are distributed differently from what we know of the forces applied to semi-rigid without foils, and the size of the installation which could encroach in particular on the interior habitable volume (moreover reduced), while respecting the safety conditions and industry standards. The problem is particularly acute for the adaptation of foils on a semi-rigid boat which meets very specific constraints of use which are different from those of sailing boats or motor boats. Another problem that arises with the integration of load-bearing structures with a load-bearing wing on motorized semi-rigid boats is the particular nature of the semi-rigid boat which is used in a so-called beaching application in commonly adopted professional language, namely berthing on the beach. The advantage of a semi-rigid being its flexibility of use, its lightness, to tackle difficult places and bodies of water where the depth is shallow or even zero in the event of docking. In addition, and fundamentally with respect to foiling sailboats, the supporting structures must be adapted to the navigation characteristics specific to the semi-rigid, which sails in particular without heel, unlike a sailing boat (and especially sailing boats equipped with foils).

Un objet principal de l'invention est de proposer un ensemble portant à aile profilée pour bateau semi rigide motorisé qui soit efficace, y compris sur des bateaux semi rigides de type existant.A main object of the invention is to provide a supporting assembly with a profiled wing for a motorized semi-rigid boat which is effective, including on semi-rigid boats of the existing type.

Un objet principal de l'invention est de proposer un ensemble portant à aile profilée pour bateau semi rigide motorisé qui soit robuste et qui dont la reprise des efforts générés n'altère pas la structure du bateau et ne nécessite pas de modifier la structure porteuse du bateau.A main object of the invention is to provide a supporting assembly with a profiled wing for a motorized semi-rigid boat which is robust and whose absorption of the forces generated does not alter the structure of the boat and does not require modifying the supporting structure of the boat. boat.

Dans la présente la demande, on appelle axe longitudinal l'axe de symétrie du bateau semi rigide, plan horizontal un plan contenant l'axe longitudinal et la ligne de flottaison du bateau, et axe vertical un axe perpendiculaire au plan horizontal.In the present application, the term longitudinal axis is the axis of symmetry of the semi-rigid boat, the horizontal plane is a plane containing the longitudinal axis and the waterline of the boat, and the vertical axis is an axis perpendicular to the horizontal plane.

La figure 1 représente une vue en coupe d'un bateau semi rigide traditionnel (1), sans foils. Il est précisé que les signes de référence utilisés sur cette figure pourront être repris, pour des éléments identiques ou similaires, à propos de bateaux selon l'invention.The figure 1 shows a sectional view of a traditional semi-rigid boat (1), without foils. It is specified that the reference signs used in this figure could be used, for identical or similar elements, with regard to boats according to the invention.

Le bateau (1) de type connu et représenté sur la figure 1 est fabriqué comme suit : une coque (13) rigide de forme générale en V. Un plancher (P) ferme la coque pour servir de plancher et d'appuis aux passagers et aux équipements. Une carlingue (12) à l'intérieur du volume défini par la coque (13) et du plancher (P) arrimée à la coque (13) vient consolider la structure de la coque dans le creux formé par la coque (12). La carlingue peut par exemple être des parois internes rigides qui viennent rigidifier la structure et notamment le creux entre le plancher (P) et la coque (13). A noter que la carlingue (12), la coque (13), le plancher (P), le livet (14) sont préférentiellement tous fabriqués à partir du même matériau et peuvent être fabriqués en un nombre très limité voir unique de pièces. L'enjeu étant de donner un compromis de rigidité nécessaire pour absorber les chocs du bateau sur l'eau et les efforts reçus, tout en maintenant une légèreté suffisante. Le pourtour de bord de plancher forme un livet (14). Le livet (14) est rigide et solidarisé à la coque. Il remonte et constitue comme une petite marche sur le pourtour du plancher afin notamment que la pointe des pieds des utilisateurs ou des objets qui trainent sur le plancher ne viennent pas taper contre le boudin creux gonflé (11) qui borde le flanc latéral bâbord, puis la proue, puis le flanc latéral tribord du bateau. Un emménagement (17), aussi appelé emménagement central, est couramment installé au centre du plancher. En variante, l'emménagement (17) peut être décalé par rapport au centre du plancher vers le côté bâbord ou le côté tribord, ou vers la proue ou la poupe du bateau. Il consiste en un ou plusieurs caissons qui logent et maintiennent la console qui regroupe les organes de commande du bateau, comme les commandes moteur. Ils peuvent également contenir un/des coffres pour le rangement ou tout autre accessoire pour des utilisations spécifiques.The boat (1) of known type and shown on figure 1 is manufactured as follows: a rigid hull (13) of general V-shape. A floor (P) closes the hull to serve as a floor and supports for passengers and equipment. A cabin (12) inside the volume defined by the hull (13) and the floor (P) secured to the hull (13) consolidates the structure of the shell in the hollow formed by the shell (12). The cabin can for example be rigid internal walls which stiffen the structure and in particular the hollow between the floor (P) and the hull (13). Note that the cabin (12), the hull (13), the floor (P), the shelf (14) are preferably all made from the same material and can be made in a very limited or even single number of parts. The challenge is to provide a compromise in rigidity necessary to absorb the impacts of the boat on the water and the forces received, while maintaining sufficient lightness. The perimeter of the edge of the floor forms a livet (14). The livet (14) is rigid and secured to the hull. It goes up and constitutes like a small step on the perimeter of the floor so in particular that the tip of the feet of the users or the objects which drag on the floor do not come to strike against the inflated hollow roll (11) which borders the port side side wall, then the bow, then the starboard side of the boat. A move-in (17), also called a central move-in, is commonly installed in the center of the floor. Alternatively, the accommodation (17) can be offset from the center of the floor towards the port side or the starboard side, or towards the bow or the stern of the boat. It consists of one or more boxes which house and maintain the console which groups together the boat's control devices, such as the engine controls. They can also contain a chest (s) for storage or any other accessory for specific uses.

La hauteur de l'emménagement (17) est dimensionnée de manière à permettre au conducteur du bateau de voir la mer devant lui. Cette hauteur est ainsi limitée, sur tous les bateaux semi rigides.The height of the accommodation (17) is dimensioned so as to allow the driver of the boat to see the sea in front of him. This height is thus limited, on all semi-rigid boats.

Comme représenté, sur la figure 2, avec une vue de dessus à la poupe bateau du semi rigide est positionné le moteur (20) à hélice.As shown, on the figure 2 , with a top view at the stern of the semi-rigid boat is positioned the propeller engine (20).

Les figures 3a et 3b représentent deux vues en coupe d'un bateau semi rigide selon l'invention qui comprend des ailes 40 dites de portance avant.The figures 3a and 3b show two sectional views of a semi-rigid boat according to the invention which comprises so-called front lift wings 40.

Sur ces figures le bateau est représenté en position d'accostage, figure 3a, ailes rétractées, et en position de navigation, figure 3b, ailes déployées. L'invention propose une solution astucieuse qui permet en positon d'accostage de ranger les ailes portantes, de telle sorte qu'elles ne gênent ni pour l'accostage, ni pour l'espace habitable sur le bateau. Par contre en position de navigation, les ailes se déploient sous le bateau et permettent ainsi de surélever la coque au-dessus du niveau de l'eau.In these figures the boat is shown in the docking position, figure 3a , wings retracted, and in navigation position, figure 3b , wings spread. The invention provides a clever solution which allows in the docking position to store the lifting wings, so that they do not interfere with or for berthing, nor for living space on the boat. On the other hand, in the navigation position, the wings deploy under the boat and thus allow the hull to be raised above the water level.

Le rangement et le déploiement des ailes (40) peut se faire de manière symétrique et simultanée. Autrement dit, les deux ailes (40) sont déployées et rangées en même temps, et leur position est symétrique par rapport à l'axe longitudinal. En ceci les foils sont utilisés très différemment des foils mis en œuvre sur des voiliers destinés à naviguer gités.The storage and deployment of the wings (40) can be done symmetrically and simultaneously. In other words, the two wings (40) are deployed and stored at the same time, and their position is symmetrical with respect to the longitudinal axis. In this the foils are used very differently from the foils implemented on sailboats intended to navigate heights.

Ainsi, pour un bateau (100) selon l'invention naviguant sans gite, les ailes (40) peuvent être toutes deux déployées simultanément et de manière symétrique, à l'inverse des voiliers qui déploient leurs surfaces portantes de manière non symétrique et non simultanée, en fonction de leur gite. Par ailleurs, la portance évolue de manière symétrique de part et d'autre de l'axe longitudinal du bateau lors du rangement et du déploiement des ailes (40), et le bateau (100) n'est donc pas déstabilisé par l'opération.Thus, for a boat (100) according to the invention sailing without heel, the wings (40) can both be deployed simultaneously and symmetrically, unlike sailboats which deploy their bearing surfaces in a non-symmetrical and non-simultaneous manner. , depending on their gite. Furthermore, the lift evolves symmetrically on either side of the longitudinal axis of the boat during the storage and deployment of the wings (40), and the boat (100) is therefore not destabilized by the operation. .

Comme représenté en figure 4, l'aile (40) comporte sensiblement deux parties : une partie dite de portance, aussi appelée horizontale, et une partie qui permet de descendre l'horizontale dans l'eau, qui est un arbre qui peut se nommer vertical.As shown in figure 4 , the wing (40) has substantially two parts: a so-called lift part, also called horizontal, and a part which makes it possible to descend horizontally into the water, which is a tree which can be called vertical.

On précise que ces termes d' « horizontal » et « vertical » employés dans ce texte à propos des deux parties de l'aile (ou du foil, ces deux termes étant ici équivalents) ne déterminent pas l'orientation absolue de ces deux parties, qui ne sont pas nécessairement orientées selon l'horizontale « vraie » et la verticale « vraie ».It is specified that these terms of "horizontal" and "vertical" used in this text about the two parts of the wing (or of the foil, these two terms being equivalent here) do not determine the absolute orientation of these two parts. , which are not necessarily oriented according to the “true” horizontal and the “true” vertical.

L'horizontale comprend une partie principale d'horizontale (42) qui est la partie qui génère la totalité (ou en variante : une partie substantielle) de la portance de l'aile (40). La partie principale d'horizontale (42) présente une surface suffisamment importante pour générer une portance apte à soulever la coque (13) au moins partiellement hors de l'eau.The horizontal comprises a main horizontal part (42) which is the part which generates all (or alternatively: a substantial part) of the lift of the wing (40). The main horizontal part (42) has a sufficiently large surface to generate lift capable of lifting the hull (13) at least partially out of the water.

La longueur (l sur la représentation de la figure 6) de la partie principale d'horizontale (42) est ainsi de préférence comprise entre 80 % du rayon (r dans la représentation de la figure 6) du boudin (11) et 110 % du rayon du boudin (11), de préférence de l'ordre de 95 % du rayon du boudin (11). Par exemple, pour un boudin (11) de 29 cm de rayon r, la longueur l de la partie horizontale est avantageusement comprise entre 22 cm et 31 cm, de préférence de l'ordre de 27 cm.The length (l on the representation of the figure 6 ) of the main horizontal part (42) is thus preferably between 80% of the radius (r in the representation of the figure 6 ) of the sausage (11) and 110% of the radius of the coil (11), preferably of the order of 95% of the radius of the coil (11). For example, for a coil (11) with a radius of 29 cm r, the length l of the horizontal part is advantageously between 22 cm and 31 cm, preferably of the order of 27 cm.

L'horizontale comprend également un bout d'aile à boudin (41) dont la forme incurvée épouse la forme du boudin (11) sur un secteur angulaire de préférence compris entre 10 degrés et 50 degrés, de préférence d'une trentaine de degrés. Grâce à cette correspondance astucieuse des formes du bout d'aile et du boudin, l'aile en position rangée ne dépasse pas sensiblement à l'extérieur du boudin.The horizontal also comprises a coil wing tip (41) whose curved shape matches the shape of the coil (11) over an angular sector preferably between 10 degrees and 50 degrees, preferably around thirty degrees. Thanks to this clever correspondence of the shapes of the wing tip and the flange, the wing in the stowed position does not significantly protrude outside the flange.

De manière avantageuse et grâce à cette correspondance de formes, en position rangée, le bout d'aile à boudin (41) ne s'éloigne ainsi pas du boudin (11) de plus d'une distance (D sur la représentation de la figure 7) comprise entre 0 et 10 cm, de préférence sensiblement égale à 2 cm.Advantageously and thanks to this correspondence of shapes, in the stored position, the wing tip with coil (41) does not move away from the coil (11) by more than a distance (D on the representation of the figure 7 ) between 0 and 10 cm, preferably substantially equal to 2 cm.

Ainsi, le gabarit (notamment la largeur) du bateau (100) dont les ailes (40) sont en position rangée est sensiblement égal à celui d'un bateau ne présentant pas d'ailes (40). Le transport routier d'un bateau (100) avec ailes (40) n'est donc pas limité.Thus, the size (in particular the width) of the boat (100), the wings (40) of which are in the stowed position, is substantially equal to that of a boat having no wings (40). Road transport of a boat (100) with wings (40) is therefore not limited.

Par ailleurs, la forme incurvée du bout d'aile à boudin (41) sert pour tenir les virages lorsque le bateau (100) gite sur une aile (40) (cette gite étant en tout état de cause plus modérée que les gites observées sur les bateaux à voiles à foils - et cette gite est également très transitoire, étant liée au virage). En effet, quelle que soit la gite temporaire du bateau (100), une portion du bout d'aile à boudin (41) sera orientée de façon optimale pour générer de la portance.In addition, the curved shape of the flanged wing tip (41) is used to hold the turns when the boat (100) is heeling on a wing (40) (this heeling being in any case more moderate than the heights observed on sailboats with foils - and this list is also very transient, being linked to the turn). Indeed, whatever the temporary list of the boat (100), a portion of the wing tip with flange (41) will be oriented in an optimal manner to generate lift.

Cet aspect de forme incurvée du bout d'aile à boudin peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.This aspect of curved shape of the flanged wing tip can be combined with the other aspects described in this text, or implemented separately or even in isolation.

La verticale comprend une première partie rectiligne de verticale (43) puis une seconde partie de verticale (44) qui s'incurve vers le centre du bateau selon un angle d'environ une quinzaine de degrés. Cette forme incurvée vers l'intérieur est conçue pour optimiser le compromis de rangement dans le bateau sur une hauteur acceptable et de descente sous l'eau à une profondeur maximum afin d'élever au maximum le bateau, le tout en se jouant des contraintes d'espace propre à l'exiguïté d'un bateau semi rigide, et plus particulièrement des bateaux des petites tailles de la gamme existantes de bateaux semi-rigides.The vertical comprises a first rectilinear vertical part (43) then a second vertical part (44) which curves towards the center of the boat at an angle of approximately fifteen degrees. This inwardly curved shape is designed to optimize the compromise of storage in the boat at an acceptable height and descent underwater to a maximum depth in order to raise the boat as much as possible, while avoiding the space constraints specific to the cramped nature of a semi-rigid boat, and more particularly boats of the small sizes of the existing range of semi-rigid boats.

La partie rectiligne de verticale (43) peut présenter un angle d'inclinaison (a sur la représentation de la figure 6) par rapport à l'axe vertical (vrai (tel que défini au début de ce texte).The rectilinear vertical part (43) may have an angle of inclination (a on the representation of the figure 6 ) relative to the vertical axis (true (as defined at the beginning of this text).

De manière avantageuse, l'angle d'inclinaison a par rapport à l'axe vertical est compris entre 0 degré et un angle maximal amax de 45 degrés, de préférence entre 30 degrés et 40 degrés, de préférence sensiblement égal à 36 degrés.Advantageously, the angle of inclination a relative to the vertical axis is between 0 degrees and a maximum angle amax of 45 degrees, preferably between 30 degrees and 40 degrees, preferably substantially equal to 36 degrees.

Ces plages de valeurs et valeurs de l'angle d'inclinaison a ont été identifiées comme optimales pour :

  • d'une part éloigner suffisamment les parties principales d'horizontale (42) de l'axe longitudinal pour conférer à l'ensemble une stabilité satisfaisante, notamment en termes de gite,
  • d'autre part, adapter la position sur l'axe vertical de la partie principale d'horizontale (42), de manière à ce que lors du déploiement de l'aile hors du bateau, la partie horizontale de l'aile soit plongée profondément dans l'eau et permette ainsi, si on le désire, de soulever la carène du bateau au-dessus de la surface moyenne de l'eau mais aussi au-dessus des vagues, de manière à obtenir une navigation calme.
These ranges and values of the tilt angle a have been identified as optimal for:
  • on the one hand, move the main horizontal parts (42) sufficiently far from the longitudinal axis to give the assembly satisfactory stability, in particular in terms of heeling,
  • on the other hand, adapt the position on the vertical axis of the main horizontal part (42), so that when the wing is deployed out of the boat, the horizontal part of the wing is deeply plunged in the water and thus allows, if desired, to raise the bottom of the boat above the average surface of the water but also above the waves, so as to obtain a calm navigation.

Cet aspect d'angle optimisé peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.This aspect of optimized angle can be combined with the other aspects described in this text, or implemented separately or even in isolation.

Par ailleurs, la partie principale d'horizontale (42) de l'aile déployée est de préférence positionnée sur l'axe vertical entre 10 cm en-dessous et 5 cm au-dessus du centre (C sur la représentation de la figure 6) de l'hélice du moteur (20). En particulier, la partie principale d'horizontale (42) de l'aile déployée peut être située au même niveau sur l'axe vertical que le centre de l'hélice du moteur (20). Ceci est valable pour les deux ailes qui, rappelons-le, sont typiquement déployées en simultanément et de la même manière, des deux côtés du bateau.Furthermore, the main horizontal part (42) of the deployed wing is preferably positioned on the vertical axis between 10 cm below and 5 cm above the center (C on the representation of the figure 6 ) of the engine propeller (20). In particular, the main horizontal part (42) of the deployed wing may be located at the same level on the vertical axis as the center of the engine propeller (20). This is valid for both wings which, let us remember, are typically deployed simultaneously and in the same manner, on both sides of the boat.

Ainsi, l'hélice (qui agit dans l'eau pour propulser) et la partie principale d'horizontale (42) (qui agit dans l'eau pour générer de la portance) sont sensiblement à la même profondeur et travaillent simultanément, quelle que soit le soulèvement du bateau du fait de la portance des ailes, et la partie principale d'horizontale (42) est suffisamment basse pour assurer des caractéristiques de portance satisfaisantes, sans que l'hélice soit susceptible de sortir de l'eau lorsque le bateau (100) est au moins partiellement soulevé par les surfaces portantes.Thus, the propeller (which acts in the water to propel) and the main horizontal part (42) (which acts in the water to generate lift) are substantially at the same depth and work simultaneously, whatever either the lifting of the boat due to the lift of the wings, and the main horizontal part (42) is low enough to ensure satisfactory lift characteristics, without the propeller being liable to come out of the water when the boat (100) is at least partially lifted by the bearing surfaces.

Cet aspect de concordance des profondeurs de l'hélice et de la partie principale d'horizontale peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.This aspect of concordance of the depths of the helix and of the main horizontal part can be combined with the other aspects described in this text, or implemented separately or even in isolation.

L'horizontale et la verticale sont reliées par un coude arrondi.The horizontal and the vertical are connected by a rounded elbow.

L'épaisseur de l'aile (40) peut être de l'ordre de 10 mm à 40 mm, de préférence d'environ 20 mm. La corde moyenne de l'aile (40) peut être comprise entre 100 mm et 500 mm, de préférence d'environ 300 mm. Lorsque le bateau est soulevé par les ailes (40), la longueur immergée d'une aile (40) (L sur la représentation de la figure 6) peut être comprise entre 600 mm et 1200 mm, de préférence d'environ 900 mm. La surface portante d'une aile (40) présentant une longueur immergée de 900 mm et une corde moyenne de 300 mm est de 54 dm2.The thickness of the wing (40) can be of the order of 10 mm to 40 mm, preferably about 20 mm. The average chord of the wing (40) can be between 100 mm and 500 mm, preferably about 300 mm. When the boat is lifted by the wings (40), the submerged length of a wing (40) (L on the representation of the figure 6 ) may be between 600 mm and 1200 mm, preferably about 900 mm. The bearing surface of a wing (40) having an immersed length of 900 mm and an average chord of 300 mm is 54 dm 2 .

Les ailes (40) sont situées au niveau de l'emménagement (17) du bateau (100), sur l'axe longitudinal. De part et d'autre de l'axe longitudinal au niveau de l'emménagement (17), la coque (13) du bateau (100) est percée d'un puits (32) qui épouse la section de la verticale de l'aile (40). Chaque aile (40) est destinée à coulisser dans le puits (32) entre la position rangée et la position déployée.The wings (40) are located at the level of the accommodation (17) of the boat (100), on the longitudinal axis. On either side of the longitudinal axis at the level of the accommodation (17), the hull (13) of the boat (100) is pierced with a well (32) which follows the section of the vertical of the wing (40). Each wing (40) is intended to slide in the well (32) between the stowed position and the deployed position.

De préférence, le puits (32) débouche dans sa partie inférieure dans la partie périphérique du fond rigide du bateau et à proximité du boudin (11), afin de ne pas interférer avec le remorquage du bateau (100) sur une remorque de route lorsque les ailes (40) sont en position rangée. Le remorquage sur route s'en trouve ainsi facilité. L'angle d'inclinaison de la partie rectiligne de verticale (43) par rapport à l'axe vertical peut aussi contribuer à faciliter untel remorquage, en écartant les ailes de la remorque qui sera placée sous le bateau. Et cette inclinaison contribue par ailleurs à ce que les ailes traversent la coque rigide dans sa partie périphérique.Preferably, the well (32) opens in its lower part in the peripheral part of the rigid bottom of the boat and near the flange (11), so as not to interfere with the towing of the boat (100) on a road trailer when the wings (40) are in the stowed position. the towing on the road is thus facilitated. The angle of inclination of the rectilinear vertical part (43) with respect to the vertical axis can also help to facilitate such towing, by spreading the wings of the trailer which will be placed under the boat. And this inclination also contributes to the wings passing through the rigid shell in its peripheral part.

Cet aspect de facilité de remorquage peut être combiné avec les autres aspects décrits dans ce texte, ou mis en œuvre séparément voire isolément.This aspect of ease of towing can be combined with the other aspects described in this text, or implemented separately or even in isolation.

Par ailleurs, l'aménagement 17 comprend dans sa partie inférieure un caisson 170 (creux, voire plein) qui peut constituer par exemple le poste ou le siège de pilotage pour le pilote (le reste de l'emménagement pouvant comprendre les commandes moteur, le volant, un pare-brise, etc.).Furthermore, the arrangement 17 comprises in its lower part a box 170 (hollow, or even full) which may constitute for example the cockpit or the pilot's seat for the pilot (the rest of the accommodation may include the engine controls, the steering wheel, windshield, etc.).

Un logement 1700 est formé dans cette partie 170 de l'emménagement (17) de part et d'autre de l'axe longitudinal. Deux logements 1700 sont ainsi formés dans les parois opposées de la partie basse 170 de l'aménagement, de chaque côté de cet aménagement.A housing 1700 is formed in this part 170 of the recess (17) on either side of the longitudinal axis. Two housings 1700 are thus formed in the opposite walls of the lower part 170 of the arrangement, on each side of this arrangement.

Pour chaque logement : le logement est un trou qui permet au foil de traverser la paroi de la partie 170, le contour de ce trou épousant la section de la partie rectiligne de verticale (43) de l'aile qui est associée à ce logement, afin de pouvoir la guider en coulissement lors de son escamotage pour rangement, et de son déploiement.For each housing: the housing is a hole which allows the foil to pass through the wall of part 170, the contour of this hole following the section of the straight vertical part (43) of the wing which is associated with this housing, in order to be able to guide it sliding when it is retracted for storage, and when it is deployed.

Le foil est en effet escamoté à l'intérieur de la partie basse 170, lors de son rangement. Plus précisément, la partie « verticale » du foil est au moins partiellement escamotée à l'intérieur de la partie basse 170, lors de ce rangement.The foil is in fact retracted inside the lower part 170, during its storage. More precisely, the “vertical” part of the foil is at least partially retracted inside the lower part 170, during this storage.

Ceci permet de réduire l'encombrement du foil, par son escamotage astucieux à l'intérieur d'une structure qui existe de toutes façons sur les semi rigides (structure telle qu'un poste de pilotage, ou un siège de pilotage par exemple).This makes it possible to reduce the bulk of the foil, by its clever retraction inside a structure which exists anyway on semi-rigid (structure such as a cockpit, or a pilot's seat for example).

La hauteur de la partie basse 170 est limitée (en tout état de cause elle est en effet limitée par la hauteur de l'emménagement 17), elle-même limitée par la contrainte de visibilité du pilote.The height of the lower part 170 is limited (in any event it is in fact limited by the height of the accommodation 17), itself limited by the visibility constraint of the pilot.

Cette limitation limite en conséquence la course du foil vers le haut. Sur la figure 7 les deux foils sont représentés complètement rangés (escamotés), et on voit que leur extrémité haute bute contre (ou est très proche de) la paroi horizontale supérieure 171 de la partie basse 170 (sur la figure 7 cette paroi supérieure est de forme concave).This limitation consequently limits the upward travel of the foil. On the figure 7 the two foils are shown completely stowed away (retracted), and we see that their upper end abuts against (or is very close to) the upper horizontal wall 171 of the lower part 170 (on the figure 7 this upper wall is concave in shape).

Les logements 1700 peuvent être non pas de simple trous traversant les parois de la partie 170, mais des conduits creux ouvrant ces parois et guidant les foils jusqu'au fond du conduit (ce fond se trouvant nécessairement en dessous de la face inférieure de la paroi 171).The housings 1700 can be not simple holes passing through the walls of the part 170, but hollow ducts opening these walls and guiding the foils to the bottom of the duct (this bottom necessarily being below the underside of the wall 171).

De préférence, les puits (32) et les logements présentent un angle d'inclinaison correspondant à l'angle d'inclinaison entre la partie rectiligne de verticale (43) et l'axe vertical. Ainsi, l'encombrement des ailes (40) est minimisé par leur coulissement dans les puits (32) et dans les logements de l'emménagement (17) entre une position rangée, dans laquelle l'extrémité de la verticale de l'aile (40) est en butée contre la partie supérieure du logement, et une position déployée, dans laquelle l'extrémité de la verticale de l'aile affleure au niveau de la partie supérieure du puits (32) formé dans la coque (13). La longueur de la verticale de l'aile (40) résulte de la profondeur du logement, donc de la hauteur de l'emménagement (17) et de l'angle d'inclinaison de la partie rectiligne de verticale (43). La longueur de la verticale peut avantageusement être comprise entre 500 mm et 1500 mm, avantageusement autour de 1000 mm.Preferably, the wells (32) and the housings have an angle of inclination corresponding to the angle of inclination between the rectilinear vertical part (43) and the vertical axis. Thus, the size of the wings (40) is minimized by their sliding in the wells (32) and in the housings of the recess (17) between a stowed position, in which the end of the vertical wing ( 40) is in abutment against the upper part of the housing, and a deployed position, in which the end of the vertical of the wing is flush with the level of the upper part of the well (32) formed in the shell (13). The length of the vertical of the wing (40) results from the depth of the housing, therefore from the height of the recess (17) and from the angle of inclination of the rectilinear vertical part (43). The length of the vertical can advantageously be between 500 mm and 1500 mm, advantageously around 1000 mm.

La figure 3a représente le mécanisme d'asservissement (31) d'actionnement et de verrouillage de l'aile sur la coque de bateau. Un travail de seconde monte ou de première monte est réalisé en perçant la coque d'un puits (32) qui épouse la section de l'aile, logeant le dispositif d'asservissement (31) qui actionne et qui verrouille l'aile depuis et dans une position basse ou haute. Le dispositif d'asservissement est solidarisé à un boîtier de protection (30) qui protège le passage de l'aile et le mécanisme d'asservissement (31). Ce boitier de protection (30) est repris aux éléments structurels du bateau, plancher, livet et carlingue par reprise de stratification, collage et/ou boulonnage. Notamment, le boîtier de protection (30) est repris par un ancrage qui s'appuie par reprise dans le triangle formé entre le livet (14), la coque (13) et la carlingue (12). Le boîtier de protection (30) présente une surface supérieure sensiblement plane, orientée selon un angle qui peut correspondre à l'angle de la partie rectiligne de verticale (43). Ainsi, le boîtier de protection (30) loge le mécanisme d'asservissement (31) et la verticale de l'aile (40), tout en reconstituant un plancher oblique. L'encombrement de l'aile (40) et de son mécanisme d'asservissement (31) est donc minimal et la sécurité est assurée pour les personnes naviguant sur le bateau (100).The figure 3a shows the servo mechanism (31) for actuating and locking the wing on the boat hull. Aftermarket or original equipment work is carried out by drilling the shell of a well (32) which hugs the section of the wing, housing the servo device (31) which actuates and locks the wing from and in a low or high position. The servo device is secured to a protective housing (30) which protects the passage of the wing and the servo mechanism (31). This protection box (30) is taken from the structural elements of the boat, floor, livet and cabin by resumption of lamination, gluing and / or bolting. In particular, the protective housing (30) is taken up by an anchor which rests by recovery in the triangle formed between the sheerline (14), the hull (13) and the cabin (12). The protective housing (30) has a substantially planar upper surface oriented at an angle which may correspond to the angle of the straight vertical portion (43). Thus, the protective casing (30) houses the servo mechanism (31) and the vertical of the wing (40), while reconstituting an oblique floor. The size of the wing (40) and of its control mechanism (31) is therefore minimal and safety is ensured for the people sailing on the boat (100).

Le dispositif d'asservissement (31) permet trois choses: 1 - le verrouillage en position 2 - la mise en translation 3 - un mouvement de rotation pour régler l'angle de l'aile dans l'eau. Le mécanisme d'asservissement (31) permet d'effectuer ces trois choses de manière simultanée et symétrique pour chaque aile (40).The servo device (31) allows three things: 1 - the locking in position 2 - the translation 3 - a rotational movement to adjust the angle of the kite in the water. The servo mechanism (31) allows these three things to be done simultaneously and symmetrically for each wing (40).

Les figures 5a et 5b représentent une vue de haut de deux dispositions d'appui de jeux d'ailes avant / arrière selon l'invention avec un jeu avant d'aile bâbord et tribord qui se positionne à la hauteur de l'emménagement (17) et une aile arrière (50) montée sur l'arbre du moteur arrière (20) figure 5a, ou par un jeu d'aile arrière bâbord et tribord (50) montées en quelque sorte en parallèle du jeu d'ailes avant.The figures 5a and 5b show a top view of two support arrangements of sets of front / rear wings according to the invention with a front set of port and starboard wings which is positioned at the height of the accommodation (17) and a rear wing (50) mounted on the rear motor shaft (20) figure 5a , or by a set of port and starboard rear wings (50) mounted in a way parallel to the set of front wings.

L'aile arrière (50) peut avantageusement présenter une surface portante projetée sur un plan horizontal participant pour entre 10% et 30% à la portance totale du bateau (100), de préférence participant à hauteur d'environ 20% de la portance totale. Le jeu d'ailes (40) avant participe quant à lui pour entre 70% et 90% de la portance totale. Par exemple, pour un bateau dont la surface portante des ailes (40) est de 54 dm2, la surface portante du plan porteur arrière pourra être de l'ordre de 15 dm2. Un tel bateau (100) peut présenter une vitesse de décollage de l'ordre de 15 kts.The rear wing (50) can advantageously have a bearing surface projected onto a horizontal plane participating for between 10% and 30% of the total lift of the boat (100), preferably participating for about 20% of the total lift. . The set of wings (40) before participates for between 70% and 90% of the total lift. For example, for a boat of which the bearing surface of the wings (40) is 54 dm 2 , the bearing surface of the rear bearing plane may be of the order of 15 dm 2 . Such a boat (100) can have a take-off speed of the order of 15 kts.

La présente invention concerne donc un ensemble portant de bateau semi rigide comprenant une coque (13), une carlingue (12), un plancher (P) et ses livets (14), des boudins latéraux et proue (11), un emménagement (17) sur le plancher (P), un moteur arrière (20) caractérisé en ce que pour une portance avant, côté bâbord et tribord au niveau de l'emménagement (17) la coque (13) est percée d'un puits (32) qui laisse passer une aile (40) asservie en blocage translation et rotation par un mécanisme d'asservissement (31) monté dans un boîtier de protection (30) repris aux éléments structurels du bateau, plancher, livet (14) et carlingue (12), par reprise de stratification, collage et/ou boulonnage, l'aile comprend un partie horizontale avec une extrémité bout d'aile à boudin (41) dont la forme incurvée épouse la forme du boudin, et une verticale d'aile qui comprend une extrémité de verticale (44) qui s'incurve vers le centre du bateau, et pour une portance arrière, une aile peut être montée sur l'arbre moteur du moteur arrière (20).The present invention therefore relates to a supporting assembly for a semi-rigid boat comprising a hull (13), a cabin (12), a floor (P) and its livets (14), side flanges and bow (11), a fitting (17). ) on the floor (P), a rear engine (20) characterized in that for a front lift, side port and starboard at the level of the accommodation (17) the hull (13) is pierced with a well (32) which allows a wing (40) to pass locked in translation and rotation by a servo mechanism (31) mounted in a protective box (30) taken from the structural elements of the boat, floor, livet (14) and cabin (12), by resumption of lamination, gluing and / or bolting, the wing comprises a horizontal part with one end end of coil wing (41) whose curved shape matches the shape of the coil, and a wing vertical which includes a vertical end (44) which curves towards the center of the boat, and for aft lift, a wing can be mounted on the motor shaft of the rear motor (20).

La présente invention concerne donc un ensemble portant de bateau semi rigide caractérisé en ce que la portance arrière peut être une aile portante montée sur l'arbre moteur du moteur arrière (20).The present invention therefore relates to a supporting assembly for a semi-rigid boat characterized in that the rear lift can be a wing mounted on the drive shaft of the rear engine (20).

La présente invention concerne également un ensemble portant de bateau semi rigide caractérisé en ce que la portance arrière comprend un jeu d'aile arrière bâbord et tribord (50) montées à l'arrière du bateau en parallèle du jeu d'ailes avant.The present invention also relates to a supporting assembly for a semi-rigid boat characterized in that the rear lift comprises a set of port and starboard rear wings (50) mounted at the rear of the boat in parallel with the set of front wings.

On voit bien que de nombreuses variantes éventuellement susceptibles de se combiner peuvent ici être apportées sans jamais sortir du cadre de l'invention tel qu'il est défini ci-après.It is clear that numerous variants which may possibly be combined can be made here without ever departing from the scope of the invention as defined below.
