Abstract

Device making it possible for a windsurfing board to carry out glides. The invention relates to the addition of a support plane to the rigging of a windsurfing board. It consists of a flying wing which has an empty space 4 in its centre delimited by two tubes 3, between which the rigging of the windsurfing board is inserted. The wing is supported by a tube 9 fixed perpendicularly to the front of the mast in its upper half 8. The wing is braced by cables 12, 13, 14, and 16, 17, 18 which start respectively from the top 11 and from the base 15 of the mast. This invention is particularly intended for sports use, a good example of which is its application to so-called jumping sailboards.

Description

Adjrnctign d'un plan porteur au gréement d'une planche à voile,
La présente invention concerne l'adjonction dun plan porteur au gréement d'une planche à voile permettant des sauts de vagues planées.Adjrnctign of a carrier plan to the rigging of a windsurfing board,
The present invention relates to the addition of a carrier plane to the rigging of a windsurf board allowing jumps of planed waves.

Il existe actuellement des planches à voile et des ailes volantes, mais aucune réalisation concernant l'assemblage de ces deux éléments.There are currently windsurfers and flying wings, but no achievement concerning the assembly of these two elements.

La présente invention est utilisable sur tous types de planches à voile ( aquatique et térrestfes notamment planches à roulettes ).The present invention can be used on all types of windsurf boards (aquatic and térrestfes including skateboards).

Elle consiste en l'adJonction dun plan porteur à la voile déja existente, grsee à un espace médian ménagé sur le plan porteur dans lequel pourra s'insérer la voile.(inversesement il sit possible de concevoir une voile percde au travers de laquelle on peut insérer une aile ).It consists of the addition of a bearing plane to the already existing sail, grsee to a median space formed on the bearing plane in which the sail can be inserted. (Conversely it is possible to design a pierced sail through which one can insert a wing).

Cet espace médian, ménagé sur l'aile, est délimité par deux tubes rectilignes ou concaves vers ltintérieuri et permet de conserver le galbe de la voile lors des changements de bord; il favorise également un meilleur écoulement laminaire des filets d'air ( pretubés par l'aile ) sur la voile de la planche à voile.This median space, formed on the wing, is delimited by two rectilinear or concave tubes towards the interior and makes it possible to preserve the curve of the sail during changes of edge; it also promotes better laminar flow of air streams (pretubed by the wing) on the sail of the windsurfing board.

La résultante des forces provoquées par le vent sur le géement d'une planche voile classique est une force propulsive. La présente invention en ajout- ant un plan porteur perpendiculaire à la voile classique, engendre une force ascentionnelle qui permet au véliplanchiste d'effectuer dee vols planés sur les vagues.The result of the forces caused by the wind on the handling of a classic sailboard is a propelling force. The present invention by adding a carrier plane perpendicular to the conventional sail, generates an upward force which allows the windsurfer to perform gliding flights over the waves.

Le plan porteur est une aile type aile volante ou aile de planeur modifiées profil creux ou plein.The supporting plane is a wing type flying wing or glider wing modified hollow or full profile.

Laile est fixée sur le mât au niveau de son centre de portance. The wing is attached to the mast at its center of lift.

Il est donné à titre d'exemple non limitatif un mode de réalisation se réferant aux dessins oi joints:
La figure 1 représente l'aile, la figure 2 représente la planche à voile , la figure 3 représente l'assemblage de l'aile et de la planche à voile.An embodiment is given by way of nonlimiting example, referring to the accompanying drawings:
FIG. 1 represents the wing, FIG. 2 represents the windsurfing board, FIG. 3 represents the assembly of the wing and the windsurfing board.

L'exemple choisi est une aile volante modifiée. De la partie antérieure(i) del'aile, partent deux tubes latéraux(2) constituant les bords d'attaque; l'angle d'attaque étant obtus. De la partie antérieure(1) de l'aile partent également deux tubes médiaux(3); entre eux, espace vide(4) permet au gréement de la planche à voile de venir s'insérer. Ces deux tubes médicaux (3) sont concaves vers l'intérieur de façon à ne pas gêner le galbe de la voile lors des changements de bord, ils favorisent également l'écoulement laminaire des filets d'air sur la voile.Entre chaque tube latéral et médian est sous-tendue une voile(5). The example chosen is a modified flying wing. From the front part (i) of the wing, leave two lateral tubes (2) constituting the leading edges; the angle of attack being obtuse. From the front part (1) of the wing also leave two medial tubes (3); between them, empty space (4) allows the rigging of the windsurf board to be inserted. These two medical tubes (3) are concave inwards so as not to interfere with the curve of the sail when changing edges, they also promote the laminar flow of the air streams on the sail. Between each side tube and median is subtended a sail (5).

La surface totale de l'aile est variable en fonction de la force du vent.The total area of the wing is variable depending on the strength of the wind.

Le bord de fuite (6) de l'aile est rigidifié par des lattes(7) EPOUE fixer l'aile ainsi modifiée au niveau de son centre de portance sur le gréement de la planche à voile , ce dernier doit subir des modifications: sur la moitié supérieure du mbt (8) et sur sa partie antérieure ,est fixé perpendiculairement un tube transversal (9) au moyen d'un bout le reliant au mSt grâce à des trous (10) pratiqués à étages differents sur la moitié supérieure du inftt;;cettefixation peut être également tout autre moyen de fixation déjà connu, autorisant cependant la rotation de ce tube transversal autour de son plus grand axe
Ce tube transversal (9) sert de support à l'aile précitée et se fixe aux tubes latéraux (2) de l'aile en ses extrémités, par des moyens de fixation déjà connus. Les tubes médiaux (3) sont également fixés en leurs points d'intersections avec le tube transversal ### (#9). Il est possible de faire varier l'incidence de l'aile par la rotation du tubetransversal (9) sur lui même , autour de son plus grand axe, au niveau de son point de fixation à l'avant du mSt (8),
De plus l'aile est haubanée sur le mât de la planche à voile au moyen de cables munis d'un raidisseur.Ces câbles partent d'une part: du sommet du mât (11) pour sous-tendre:
(a) L'avant de l'aile (12).The trailing edge (6) of the wing is stiffened by slats (7) THOUGHT to fix the wing thus modified at its level of lift on the rigging of the windsurf board, the latter must undergo modifications: on the upper half of the mbt (8) and on its front part, a transverse tube (9) is fixed perpendicularly by means of a tip connecting it to the mSt by means of holes (10) made on different stages on the upper half of the inftt ;; this fixing can also be any other means of fixing already known, however authorizing the rotation of this transverse tube around its greatest axis
This transverse tube (9) serves to support the aforementioned wing and is fixed to the lateral tubes (2) of the wing at its ends, by already known fixing means. The medial tubes (3) are also fixed at their points of intersection with the transverse tube ### (# 9). It is possible to vary the incidence of the wing by the rotation of the transverse tube (9) on itself, around its largest axis, at its point of attachment to the front of the mSt (8),
In addition, the wing is guyed on the mast of the windsurf board by means of cables provided with a stiffener. These cables leave on the one hand: from the top of the mast (11) to underpin:
(a) The front of the wing (12).

(b) L'extrémité posterieure des deux tubes médiaux (13). (b) The posterior end of the two medial tubes (13).

(c) Les extrémités du tube transversal (14). (c) The ends of the cross tube (14).

Et d'autre part ces câbles partent de la base (15) du rnftt pour sous-tendres
(a) L'avant de l'aile (16).And on the other hand these cables leave from the base (15) of the rnftt for under-tenders
(a) The front of the wing (16).

(b) L'extrémité posterieure des deux tubes médiaux (17). (b) The posterior end of the two medial tubes (17).

(c) Les extrémités du tube transversal (18).l
Lofer signifier se rapprocher de la direction du vent; sur une planche à voile classique le véliplanchiste doit pour lofer tirer la voile vers l'ar- -rière; ce faisant il augmente l'incidence de l'aile qui est solidaire du gréement de la planche à voile. De plus se rapprochant de la direction du vent; à la force de la vitesse de la planche à voile va s'ajouter la force du vent exercées sur l'aile dans cette situation optimum.(c) The ends of the transverse tube (18) .l
Lofer means to approach the direction of the wind; on a classic windsurfing board, the windsurfer must, to luff, pull the sail aft; in doing so it increases the incidence of the wing which is integral with the rigging of the windsurfing board. Also approaching the wind direction; to the force of the speed of the windsurf will be added the force of the wind exerted on the kite in this optimum situation.

Ces deux conditions: augmentation de langue d'incidence de l'aile et augmen- -tation de la vitesse relative des filets d'air sur l'aile est favorable à l'obtention d'une force ascentionnelle telle à faire décoller la planche à voile et son aile ou de permettre des envolées sur les vagues. These two conditions: increased tongue incidence of the wing and increase in the relative speed of the air streams on the wing is favorable for obtaining an ascending force such as to make the board take off. sail and its wing or to allow flights on the waves.
