Abstract
Description
a présente invention concerne le gréement des voiliers monocoques ou multicoques et doit permettre une sensible am@lioration du
rendement dudit gréement et de ses effets sur la propulsion de
l'embarcation.Elle peut aussi indifféremment être appliquée à tous les engins terrestres utilisant la voile comme mode de propulsion, notamment les chars à voile
Cofilportement dynamique d'une planc@e à voile: bservations: l'utilisation actuelle des embarcations du type planche à voile à
gréement articulé au pied de mât a mis en évidence un phénomène
qui permet à ces engins des vitesses sur l'eau très importantes eu égard à leur faible surface de voile (71S au maximum).a present invention relates to the rigging of monohull or multihull sailboats and must allow a significant improvement of the
efficiency of said rigging and its effects on the propulsion of
It can also be applied equally to all land vehicles using sail as a propulsion mode, in particular land yachts
Dynamic co-propelling of a windsurfing board: reservations: the current use of windsurfing type boats
articulated rigging at the foot of the mast highlighted a phenomenon
which allows these machines to have very high speeds on the water given their small sail area (71S maximum).
Ces vitesses atteintes sont toujours supérieures à celles des
dériveurs placés dans les mêmes conditions de vent et égalent
presque celle des catamarans de sport.These speeds reached are always higher than those of
dinghies placed in the same wind conditions and equal
almost that of sport catamarans.
dxplications : Cette supériorité est dûe d'une part au faible poids de l'ensemble planche-passager et d'autre part au fait que
le mât étant incliné latéralement,le vent apporte à la voile une
portance tendant à soulever l'embarcation hors de l'eau ,diminuant
de ce fait sa surface mouillée et donc son frottement avec
l'élément liquide. Cette portance permet à l'embarcation
d'accélérer le phénomène d'hydroglissement (planing en anglais)
qui se produit sur taute embarcation atteignant une certaine
vitesse sur l'eau.Explanations: This superiority is due on the one hand to the low weight of the board-passenger assembly and on the other hand to the fact that
the mast being tilted laterally, the wind gives the sail a
lift tending to lift the boat out of the water, decreasing
thereby its wet surface and therefore its friction with
the liquid element. This lift allows the boat
to accelerate the hydroglissement phenomenon (planing in English)
which occurs on a large boat reaching a certain
speed on water.
Comportement dynamique des voiliers : Observations:
Sur tous les engins actuels se propulsant à la voile c'est le
phénomène inverse à celui observé sur les planches à voile qui se
produit: Relus le vent est violent,plus l'embarcation a tendance à
giter Cet angle de gite ,faible sur les multicoques peut devenir
très importante sur les monocoques et c'est ce qui explique la
supériorité en vitesse des premiers sur les seconds.Dynamic behavior of sailboats: Observations:
On all current vehicles propelling themselves under sail, this is the
reverse phenomenon to that observed on windsurfers which
product: Again the wind is violent, the more the boat tends to
gite This angle of gite, weak on multihulls can become
very important on monohulls and that's what explains the
superiority in speed of the former over the latter.
xplications: L'inclinaison sous le vent du gréement a pour effet
d'induire une composante verticale dirigée vers le bas qui tend
à enfoncer le voilier dans l'eau et donc à le freiner.xplications: The leeward inclination of the rigging has the effect
to induce a vertical component directed downwards which tends
to push the sailboat into the water and therefore brake it.
(Les utilisateurs d'un voilier sur-toilé par rapport au vent et
dont l'angle de gite devient important ont l'impression que leur
voilier "se vautre'). Du fait de la surface de voile importante
utilisée sur les voilier ,il n'est bien entendu pas question
d'utiliser la force directe i la masse d'un quipier pour incliner
au vent le gréement d'un voilier.(The users of a sailboat over-canvas in relation to the wind and
whose angle of lodging becomes important have the impression that their
sailboat "wallows"). Due to the large sail area
used on sailboats, there is of course no question
to use direct force i the mass of a team member to tilt
in the wind the rigging of a sailboat.
Il faut donc recourir à des moyens mécaniques ou utiliser la force salienne pour incliner au vent le greement et obtenir ainsi ,à l'instar de ce qui est obtenu sur les lanciles à voile,une portance ayant tendance à soulever l'embarcation nors de liteau
Cnamp d'application expérimental::
Du fait de l'inclinaison importante que j'ai l'intention de donner au gréement,il convient d'expérimenter le dispositif sur des
catamarans dont,par principe,la largeur est importante bien que
rien ne s1oppose à appliquer le principe et les systèmes que je
vais décrire à des monocoques ou à d'autres multicoques même de
dimensions très importante du type de ceux utilisés pour la
croisière ou la course-croisière
système d'inclinaison du grement d'un voilier nécessitant une intervention numaine aux virements de bord:
Figure I:Catamaran de sport gréé en "sloop" :
Ce système très simple peut s'appliquer à un catamaran vendu dans commerce moyennant un nombre restreint de modifications: le système des deux haubans classiques est remplacé par un circuit fermé(a) comportant comme point fixe le capelage de tête de mât(b) et,comme points permettant de faire circuler le circuit de haubannage deux poulies (d)fixées à la place des cadènes de haubans
Un système d'une ou deux butées de sécurité (e) permet de limiter l'inclinaison du mât au cas où , les voiles étant prises à contre, le gréement se trouverait à ce moment incliné sous le vent.It is therefore necessary to resort to mechanical means or use the force of the salt to tilt the rigging in the wind and thus obtain, like what is obtained on sailing missiles, a lift tending to raise the boat during the battens
Cnamp of experimental application:
Because of the significant inclination that I intend to give to the rigging, it is advisable to experiment the device on
catamarans of which, in principle, the width is important although
nothing stands in the way of applying the principle and the systems that I
will describe to monohulls or other multihulls even
very important dimensions of the type of those used for the
cruise or the cruise race
tilting system of the rigging of a sailboat requiring numerical intervention to tack:
Figure I: Sport catamaran rigged in "sloop":
This very simple system can be applied to a catamaran sold in commerce with a limited number of modifications: the system of the two conventional guy lines is replaced by a closed circuit (a) comprising as a fixed point the mast head casing (b) and , as points allowing to circulate the cable-stayed circuit two pulleys (d) fixed in place of the guy bolts
A system of one or two safety stops (e) limits the inclination of the mast in case, the sails being taken against, the rigging is then tilted downwind.
Un système de deux palans simples à deux brins(f) montés en opposition et fixés d'une part sur le circuit de haubannage,d'autre part sur chaque bord(g),permet à l'équipage avec une force multipliée par deux,d'inclinerle mât(c) à volonté et de règler cette inclinaison au moyen de taquets coinceurs(n)bloquant le brin libre des palans.A system of two simple hoists with two strands (f) mounted in opposition and fixed on the one hand to the guy line, on the other hand to each edge (g), allows the crew with a force multiplied by two, tilt the mast (c) at will and adjust this inclination by means of cleat cleats (n) blocking the free end of the hoists.
Figures 2 et j :U1 système additionnel indépendant du précédant peut permettre au mat de prendre une quête vers l'arrière importante et variable qui permet au voilier de bénéficier d'une portance à l'allure du vent arrière et d'avancer le centre de poussée vélique (a)par rapport au centre du plan de dérive (b) pour rendre le voilier plus stable en direction à cette allure-
De très nombreux systèmes sont déjà utilisés afin de modifier la quête du mât :Citons par exemple celui du pied de mât coulissant dans une gouttière aveC jeu de cales calibrées pour le bloquer et les systèmes à vis ou à palan ayant le même effet que le precédent.Notons d'autre part que,jusqu'à présent ,l'allure du vent arrière @'est pas celle où le c@tamaran se montre le plus performant ,ce qui aur@it tendance à diminuer l'interêt de la quête de mât variable si cela n'augmentait l'efficacité du grée
vent aux autres allures moins arriv@es
Figure @ ::Voulant faire parcourir au pied de mât (a)une distance plus importante,un procedé possible est l'utilisation d'un pied de mât (a) monté sur un cnoriot(b) ,roulant sur un rail(c) de profil et de section appropriés Pour déplacer le pied de mat vers l'avant,dans le cas d'un rail orizontal (c),deux palans à deux brins(d)avec point fixe(e) sur le mât,point@ de tire sur les nau -bans et au pied de mât,brin "mort"(f)passant dans le prolil de mât et taquet coinceur(g) pour bloquer le brin libre (h) dans des positions intermediaires,me paraît suffisant.Pour déplacer le oXed de mât vers l'arrière,c'est à dire redresser le gréement, un palan double % quatre brins (i) ponté en opposition avec le
precédent est nécessaire,muni lui aussi,d'un taquet coinceur(j)
pour le brin libre(k).Figures 2 and j: U1 additional system independent of the previous one can allow the mast to take an important and variable aft quest which allows the sailboat to benefit from a lift at the pace of the tail wind and to advance the center of Vélique thrust (a) compared to the center of the plane of drift (b) to make the sailboat more stable in direction at this pace-
Many systems are already used to modify the quest for the mast: Let us quote for example that of the foot of the sliding mast in a gutter with set of calibrated shims to block it and the systems with screw or hoist having the same effect as the previous one .Note on the other hand that, until now, the pace of the tailwind @ 'is not that where the c @ tamaran shows itself the most efficient, which will tend to diminish the interest of the quest for variable mast if this did not increase the efficiency of the rig
wind at other gaits less arrived
Figure @ :: Wanting to make the mast foot (a) travel a greater distance, a possible process is the use of a mast foot (a) mounted on a cnoriot (b), rolling on a rail (c) of suitable profile and section To move the mast foot forward, in the case of an horizontal rail (c), two double-strand hoists (d) with fixed point (e) on the mast, point @ de pulls on the nau -bans and at the foot of the mast, "dead" strand (f) passing through the mast prolil and cleat cleat (g) to block the free strand (h) in intermediate positions, seems sufficient to me. the mast oXed to the rear, that is to say to straighten the rigging, a double hoist% four strands (i) bridged in opposition to the
previous is necessary, also equipped with a cleat cleat (j)
for the free strand (k).
Figur e 4 et 5 : Catamaran dé course-croisière ou de vitesse
muni d'un mât sur claque coque et d'une poutre norizontale
raliant les deux mâts:Le même principe peut s'appliquer à ce
genre particulier de catamaran en remplaçant les deux haubans
arrière servant d'entretoise au "portique" par un circuit de
filin avec pour points fixes les deux capelages de tête de mât(a)
et pour points coulissants deux poulies (b) installées chacune
derrière un pied de mât.Figures 4 and 5: Cruising or speed catamaran
fitted with a mast on a slap hull and a horizontal beam
connecting the two masts: The same principle can apply to this
special kind of catamaran replacing the two stay cables
rear serving as a spacer for the "gantry" by a circuit of
line with fixed points for the two masthead covers (a)
and for sliding points two pulleys (b) installed each
behind a mast foot.
Système d'inclinaison automatique du gréement en fonction du
bord d'où vient le vent : Figures 6~7~8~et 9:
Ce système consiste à utiliser la pression (a) du vent sur la voile pour faire circuler le pied de mât(b)à quête fixe muni
dans ce cas d'un chariot à roulements coulissant sur un rail
transversal (c) profilé en secteur ayant pour centre de
révolution le point de capelage (d) des haubans au mât(e). Automatic tilting system of the rigging according to the
edge where the wind comes from: Figures 6 ~ 7 ~ 8 ~ and 9:
This system consists in using the pressure (a) of the wind on the sail to circulate the mast foot (b) with fixed quest provided
in this case a rolling carriage sliding on a rail
transverse (c) profiled in sector having for center
revolution the point of casing (d) of the shrouds to the mast (e).

The point of casing (d) of the guy wire to the mast (e) to be fixed
compared to the set of two hulls, it is necessary to rig
two shrouds in rigid profile (f) resting on the end

This system can also be replaced by a single rigid guy (a) held by two flexible guy wires (b) and taking support in the middle of a horizontal beam (c) mounted in the bows
Catamaran rigged in "sloop":
The previous catamaran can be fitted with two jibs or furler
established either on the rigid shrouds (Figure t) or on the flexible shrouds ligure 9) and of which only the jib located in front of the mast will be established along the edge on which one is.
Dans les deux cas le capelage des haubans doit se trouver plus bas que sur un haubannage classique fixe, de façon à@obtenir une importante inclinaison du mât ligure lO:Âfin de limiter le cintrage latéral du mât on utilisera
un guignol à barres de flèche rigides.In both cases the shrouding of the shrouds must be lower than on a conventional fixed shroud, so as to obtain a significant inclination of the Ligurian mast lO: In order to limit the lateral bending of the mast, we will use
a horn with rigid spreaders.
