Abstract

The kite has a flattened ellipsoid structure with ribs forming chambers that are open at the front and fitted with non-return flaps at the back. It has a system of shrouds attached at one end to the ribs and at the other, to a pair of control lines. The leading edge of the kite is of double thickness, is hollow and has an aperture closed by Velcro (RTM: polyamide) strips to allow for the insertion of an inflatable balloon. The kite has a flattened ellipsoid structure similar to that of a parapenting wing, with ribs forming chambers of aerofoil lengthwise sections, open at the front to allow in air and fitted with non-return flaps at the back to slow down the rate at which they deflate. It has a system of shrouds (9 10, 11) attached at one end to the ribs and at the other to a pair of control lines (12). The leading edge (1) of the kite is of double thickness and is hollow. It has an aperture, closed by Velcro (RTM) strips, to allow for the insertion of an inflatable balloon.

Description

DESCRIPTION
La présente invention concerne un cerf-volant de traction ,aussi appelé aile de traction ou voile de traction aérienne, se présente comme une sorte de petit parapente (voir planche de photos n01 et 2 ) destiné à éxécuter des figures aériennes entre les mains d'un pilote situé au sol ou sur un mobile .fil est ,gracie à sa vessie gonflable particulièrement destiné à la traction sur l'eau.
DESCRIPTION
The present invention relates to a traction kite, also called traction wing or aerial traction sail, is presented as a kind of small paraglider (see photo board n01 and 2) intended to execute aerial figures in the hands of a pilot located on the ground or on a mobile .fil is, thanks to his inflatable bladder particularly intended for traction on water.

La traction éxercée étant variable selon la surface de l'aile on peut l'utiliser soit pour réaliser des exercices acrobatiques à caractère sportif, soit pour tracter un mobile au sol ou sur l'eau. Le domaine d'utilisation est principalement le loisir et concerne le cerf-volant de sport, le buggy ,la planche à voile, le surf, le wakeboard le ski nautique ,le surf des neiges, le patin à glace ,le skateboard ...etc. Des applications sont également possibles dans des domaines plus utilitaires ,embarcations de survie en mer ,antennes aériennes en mer ,ou tout autre application nécessitant un cerf- volant tractant ,et tres maneuvrable. The traction exerted being variable depending on the surface of the wing, it can be used either to perform acrobatic exercises of a sporting nature, or to tow a mobile on the ground or on the water. The field of use is mainly leisure and concerns sport kite, buggy, windsurfing, surfing, wakeboarding, water skiing, snowboarding, ice skating, skateboarding ... etc. Applications are also possible in more utilitarian fields, survival craft at sea, aerial aerials at sea, or any other application requiring a towing kite, and very maneuverable.

L' état de la technique est aujourdhui le suivant:
Les cerf-volants de traction se répartissent en 3 grandes categories :les cerf-volants delta traditionnels ,les cerf-volant de type parapente à caissons, les cerf-volants de type parapente sans caissons. La présente invention appartient à la seconde catégorie.
les cerf-volants delta traditionnels sont des cerf-volants en toile de spinaker ou de
parapente tissus polyamide ou polyester) munis d'armatures en fibre de carbone .lls sont pilotés par 2 lignes en tresse de polyéthilène à haute ténacité. Ceux utilisés pour la traction ont une envergure de 3 à 5 mètres contre Im à 2m 60 pour les cerf-volants de loisir en général.
The state of the art is as follows today:
Traction kites fall into 3 main categories: traditional delta kites, boxed paraglider type kites, paraglider type kites without caissons. The present invention belongs to the second category.
traditional delta kites are kites made of spinaker canvas or
polyamide or polyester paraglider) fitted with carbon fiber frames. They are piloted by 2 lines in high tenacity polyethilene braid. Those used for traction have a wingspan of 3 to 5 meters compared to Im at 2m 60 for recreational kites in general.

Mais les cerf-volants de type parapente sont beaucoup plus interessants pour la traction et le cerf-volant utilisant la technique des caissons autogonflabes par le courant d'air sont les plus répandus . II s'agit d'un petit parapente de 2 a 10 m2 ou I 'aile est rendue rigide et adopte un profil d'aile épaisse grâce à des caissons ouverts à leur extémité avant située sur le bord d'attaque Ceux -ci se gonflent sous l'effet du vent qui s'y engouffre. Un réseau de suspentes permet de répartir la traction sur un grande partie de la surface de l'aile et sont ramifiées en 2 points auxquels s'attachent les 2 lignes de traction. But kites of the paraglider type are much more interesting for traction and kites using the technique of self-inflating boxes by the air current are the most widespread. It is a small paraglider from 2 to 10 m2 where the wing is made rigid and adopts a thick wing profile thanks to boxes open at their front end located on the leading edge. These swell under the effect of the wind rushing in. A network of lines allows the traction to be distributed over a large part of the wing surface and is branched at 2 points to which the 2 traction lines are attached.

Un reseau plus simples de suspentes partent du bord de fuite et se ramifient en 2 lignes auxquelles viennent s'attacher les 2 lignes de freins. Ces 4 lignes de pilotage sont accrochées à 2 poignées ,chaque poignée recevant un ligne de traction et une ligne de frein. Le cerfvolant est piloté selon des principes analogues à ceux des parapentes. Pour virer à droite on tire sur la poignée de droite en avancant la poignée gauche. On accentue le virage en serrant le frein droit et en relâchant le frein gauche. L'inconvénient de ce type de cerfvolant est l'avachissement de la structure lorsque le vent mollit et ne gonfle plus les caissons assez pour les raidir. D'autre part ils ne peuvent pas redécoller s'ils tombent à l'eau.A simpler network of lines start from the trailing edge and branch into 2 lines to which the 2 brake lines are attached. These 4 steering lines are attached to 2 handles, each handle receiving a traction line and a brake line. The kite is piloted according to principles similar to those of paragliders. To turn right, pull on the right handle by advancing the left handle. The turn is accentuated by applying the right brake and releasing the left brake. The disadvantage of this type of kite is the slackening of the structure when the wind softens and no longer inflates the caissons enough to stiffen them. On the other hand, they cannot take off again if they fall into the water.

Pour pallier les inconvénients des cerf-volants à caissons on a vu apparaitre il y a quelques années des cerf-volants sans caissons ressemblant plus a une voile qu'à une aile. To overcome the drawbacks of boxed kites, we saw a few years ago appear kites without boxes more like a sail than a wing.

Ces cerf-volants ne comportent qu'une épaisseur de toile et la rigidité est assurée par des lattes .Ils ne comportent pas de suspentes et sont pilotés avec deux lignes et non 4/d'un ) bord d'attaque gonflable et de lattes longitudinales en fibre de verre ou gonflables.These kites only have a thickness of canvas and the rigidity is ensured by slats. They do not have hangers and are piloted with two lines and not 4 / a) inflatable leading edge and longitudinal slats fiberglass or inflatable.

Ces deux types de solutions ,parapentes à caissons et voiles rigides à lattes présentent des inconvénients .Le premier est plus puissant et plus manoeuvrable en virage que le second ,à surface égale,mais il n'a ni rigidité ni flottabilité et ne peut donc être efficace en mer.Le second,a une bonne flottabilité mais moins de puissance et de manoeuvrabilité que le premier. These two types of solutions, boxed paragliders and rigid slatted sails have drawbacks. The first is more powerful and more maneuverable in turns than the second, with an equal surface, but it has neither rigidity nor buoyancy and cannot therefore be efficient at sea. The second, has good buoyancy but less power and maneuverability than the first.

La présente invention remédie à ces différents défauts:
Il s'agit d' une aile à caissons munie d'une vessie gonflable dans le bord d'attaque ( FIG. 1 et FIG.3 ) .Les caissons sont munis à l'avant d'un système innovant de fermeture s'opposant à la sortie de l'air.L'aile comporte des suspentes ,et elle est pilotée en 4 lignes ou en 2 lignes. (FIG.4)
L'enveloppe se compose d'une surface extrados et d'une surface intrados recouvrant une vingtaine de nervures ayant un profil proche de celui des ailes d'avion.
The present invention remedies these various defects:
It is a boxed wing provided with an inflatable bladder in the leading edge (FIG. 1 and FIG.3). The boxes are provided at the front with an innovative opposing closure system at the air outlet. The wing has lines, and it is piloted in 4 lines or in 2 lines. (FIG.4)
The envelope consists of an upper surface and a lower surface covering around twenty ribs having a profile close to that of airplane wings.

Chaque nervure est percée d'orifices circulaires de façon à faire circuler l'air d'un caisson à l'autre.Each rib is pierced with circular orifices so as to circulate the air from one box to the other.

Le bord d'attaque de chaque nervure est évidé par un trou circulaire destiné à laisser passer une vessie transversale placée dans le bord d'attaque et allant d'une pointe de l'aile à l'autre.The leading edge of each rib is hollowed out by a circular hole intended to allow a transverse bladder placed in the leading edge and going from one point of the wing to the other.

Le bord d'attaque comporte ,à sa partie inférieure centrale une ouverture destinée à enfiler une vessie (FIG 3).L'ouverture se ferme par un rabat à bande de velcro. La vessie est fabriquée en tissus de polyuréthane soudé. Cette matiere ,plus souple que le PVC ,évite à la vessie de se déformer en l'air. La vessie est amovible et peut être changée ou réparée en cas de crevaison. Le rôle de cette vessie est d'assurer la rigidité transversale de l'aile, et sert de flotteur en cas de chute dans l'eau. The leading edge has an opening in the central lower part for threading a bladder (FIG 3). The opening closes with a flap with Velcro tape. The bladder is made of welded polyurethane fabrics. This material, more flexible than PVC, prevents the bladder from deforming in the air. The bladder is removable and can be changed or repaired in the event of a puncture. The role of this bladder is to ensure the transverse rigidity of the wing, and serves as a float in the event of a fall into the water.

Les entrées d'air sont situées à la jonction entre la bordure avant de l'intrados et la partie inférieure de la vessie. La moitié des caissons comporte une entrée d'air ,les autres étant fermés à l'avant Le dispositif anti-retour empêchant l'air de ressortir est constitué par des panneaux de tissus prolongeant vers l'intérieur le fourreau de tissus entourant la vessie.Lorsque l'aile avance la pression extérieure est supérirure à la pression intérieure de ces panneaux se soulèvent en laissant entrer l'air.Lorsque l'aile s'arrête ou fait marche arrière ,la pression de l'air sur le bord d'attaque diminue et la surpression interieure ainssi créée plaque les volets de tissus anti-retour sur l'intrados ,obturant de ce fait les entrées d'air.Ce dispositif permet de conserver à l'aile sa rigidité en toutes circonstances ce qui n'est pas le cas des ailes sans clapet anti-retour ,lesquelles se vident et se déforment lors des déventes.Ce dispositif anti-retour permet aussi à l'aile de rester gonflée lorsqu'elle atterrit sur l'arrière Dans l'eau ceci devient capital puisque l'aile flotte sur ses caissons qui peuvent rester gonflés assez longtemps pour redécoller. The air inlets are located at the junction between the front edge of the lower surface and the lower part of the bladder. Half of the boxes have an air inlet, the others being closed at the front. The non-return device preventing air from coming out consists of fabric panels extending inwardly the sheath of tissue surrounding the bladder. When the wing advances the external pressure is higher than the internal pressure of these panels are raised by letting in the air. When the wing stops or reverses, the air pressure on the leading edge decreases and the internal overpressure thus created plates the non-return fabric flaps on the lower surface, thereby closing off the air inlets. This device makes it possible to keep the wing its rigidity in all circumstances which is not the case of the wings without non-return valve, which empty and deform during the venting. This non-return device also allows the wing to remain inflated when it lands on the rear In water this becomes essential since the wing floats on r its boxes which can remain inflated long enough to take off again.

Les suspentes sont contituées par des brides en V attachée en 2 ou plusieurs points de chaque latte ,les pointes de tous les V étants reliées par une bride transversale renvoyant la traction aux deux lignes d'extrémités. (FIG.2 )Les brides de freins sont accrochées en plusieurs points du bord de fuite et convergent vers des brides en V auxquelles sont reliées les 2 lignes de frein. The lines are formed by V-shaped flanges attached at 2 or more points on each slat, the points of all the V's connected by a transverse flange returning traction to the two end lines. (FIG.2) The brake flanges are hooked at several points on the trailing edge and converge towards V-flanges to which the 2 brake lines are connected.

Cette aile de traction est déclinée en plusieurs surfaces destinées à plusieurs forces de vent : 4 m2 ,6m2 et 8 m2. This traction wing is available in several surfaces intended for several wind forces: 4 m2, 6 m2 and 8 m2.

Les applications sont celles décrites plus haut au paragraphe 1.  The applications are those described above in paragraph 1.
