Abstract

The glider has flapping wings formed by joining inflatable tubes (1). The inflatable tubes are parallel to each other and reinforced by semi-rigid slats (2), where the slats are made of carbon or glass fiber. The diameter of the tube is 40 cm. The flapping of the wing is obtained by elastic deformation of a structure of the wing. The deformation is opposed by traction exerted on an oscillating lever arm system (3).

Description

La présente invention concerne un mode de réalisation particulier d'un système de planeur ultra-léger a ailes battantes. Le brevet 0207400 décrit un tel appareil doté d'un système de récupération et transformation de l'énergie solaire thermique. Cet appareil a été réalisé et testé (sans le système de récupération d'énergie) , avec une fortune assez faible mais non nulle. Le dispositif selon l'invention reprend l'élément essentiel décrit dans le brevet cité, c'est-à-dire un tube gonflable de 10m de long, de diamètre de 50 à 30 cm, gonflé à une pression de 100 à 150 millibars. Un tel objet étant donné ses dimensions est éminemment susceptible de se déformer à la moindre sollicitation. L'objectif de la réalisation suivant la présente invention, est de rigidifier ce tube gonflable de manière à ce qu'il ne puisse pas osciller d'avant en arrière, tout en gardant sa capacité d'oscillation de haut en bas. En accolant parallèlement entre eux plusieurs de ces tubes gonflables, par couture de leurs enveloppes, on obtient un tel résultat. Si de plus ces tubes sont renforcés dans le sens longitudinal par des lattes en fibres de verre, ou en fibres de carbone, qui à la fois rigidifient et donnent un effet ressort,on obtient alors une poutre souple et élastique. Sur cette poutre, est greffée une aile une aile gonflable par avancement de type parapente. Cette aile est maintenue en forme à l'arrêt grâce à des saumons gonflables (àl00-150 millibars) greffés sur la poutre. On obtient alors une aile gonflable élastique, d'une très grande solidité, souplesse et légèreté. L'aile à vide est globalement en forme de plan. Au décollage, à la mise en portance, les bouts d'ailes montent, et l'aile prend la forme d'un arc de cercle. Un système de bras de levier oscillant est installé sous la poutre de manière à pouvoir contrer cette déformation élastique par traction du pilote. Dans la réalisation actuelle, qui a effectuée ses premiers vols, le pilote est installé sur un tube gonflable de longueur 2m50,et de diamètre 40cm, greffé au milieu de la poutre principale. Le pilote est à califourchon sur ce tube, à l'instar du cavalier sur sa monture. The present invention relates to a particular embodiment of an ultra-light glider wing glider system. Patent 0207400 describes such an apparatus equipped with a system for recovering and transforming solar thermal energy. This device was made and tested (without the energy recovery system), with a fairly small but not zero fortune. The device according to the invention incorporates the essential element described in the cited patent, that is to say an inflatable tube of 10m long, diameter of 50 to 30 cm, inflated to a pressure of 100 to 150 millibars. Such an object, given its dimensions, is eminently liable to deform at the slightest stress. The objective of the embodiment according to the present invention is to stiffen the inflatable tube so that it can not oscillate back and forth, while keeping its oscillation ability from top to bottom. By joining together several of these inflatable tubes in parallel, by sewing their envelopes, we obtain such a result. If further these tubes are reinforced in the longitudinal direction by fiberglass slats, or carbon fibers, which both stiffen and give a spring effect, then we obtain a flexible and resilient beam. On this beam, is grafted a wing inflatable wing paragliding type advancement. This wing is kept in the stationary shape thanks to inflatable salmon (at 100-150 millibars) grafted onto the beam. An elastic inflatable wing is then obtained, of great strength, flexibility and lightness. The vacuum wing is generally in plan form. At take-off, at the moment of lift, the wing tips rise, and the wing takes the form of a circular arc. An oscillating lever arm system is installed under the beam so as to be able to counter this elastic deformation by traction of the pilot. In the current production, which made its first flights, the pilot is installed on an inflatable tube of length 2m50, and diameter 40cm grafted in the middle of the main beam. The pilot is straddling this tube, like the rider on his mount.

La figure 1 représente une coupe de cette aile élastique. La figure 2 représente l'aile élastique, et son fléchissement vers le haut, vue de face. La figure 3 représente l'aile élastique, et son fléchissement vers le bas par traction, vue de face. Figure 1 shows a section of this elastic wing. Figure 2 shows the elastic wing, and its upward bending, seen from the front. Figure 3 shows the elastic wing, and its downward flexing by traction, seen from the front.

En référence à ces dessins, le dispositif comporte un système de tubes gonflables accolés parallèlement entre eux (1), armés de renforts élastiques (2), et d'un système de rappel par bras de levier oscillant. (3 ) With reference to these drawings, the device comprises a system of inflatable tubes contiguous parallel to each other (1), armed with elastic reinforcements (2), and a return system by oscillating lever arm.
