Abstract
Description
La présente invention concerne un dispositif pour réduire l'effort nécessaire au: battement des ailes d'un planeur à ailes battantes
Le dispositif prévoi un appareil à ailes articulées battantes, avec voilure souple ou rigide
Le dispositif selon l'invention permet de répartir le poids du corp central sur la surface portante des ailes A l'aide de ressorts, sandova op. The present invention relates to a device for reducing the force required for: flapping the wings of a winged glider
The device provides for a device with hinged articulated wings, with flexible or rigid wing
The device according to the invention makes it possible to distribute the weight of the central body on the bearing surface of the wings With the aid of springs, sandova op.
autres I1 colporte une partie centrale laissant un creux intérieur suffisant pour que puisse prendre place le pilote, celui-ci, étant maintenu à l'interieur par des sangles lui laissant les pieds et les jambes libre . Ceci, afin de lui permettre, au départ, de courrir au sol pour donner une certaine vitesse é l'appareil Puis, le pilote relève les pieds pour actionner les pédales comandant le battement des ailes . Durant cette manoeuvre, les ailes de 1' appareil seront maintenues bloquées par un système de freinage en position légèrement sur élevée par rapport è l'orizontal .Le pilote débloquant les ailes au moment ou il pose les pieds sur les pédales
Selon une forme de réalisation préférentille, les ailes ont une envergure variable, augmentant d'environ I/6e à chaque fois qu'il y a une présaion sur les pédales
Chaque aile est assistée dans leur mouvement par un ressort réglé de façon à réduire au nininua l'effort que le pilote doit fournir pour faire battre les ailes . Ce détail représente l'essentiel de l'invention
Dans la forte de réalisation selon les figures jointes, les ailes à voilure souple ont une certaine similitude avec les ailes de chauve-souriss
Chaque aile étant indépendante l'une de l'autre .Le plan arriere de la voilure de chaque aile est orientable le long du corp central, cette orientation s'effectue à l'aide de 2 levier, gauche et droite, à la portée des yias du pilote . Elle se fait de haut en bas pour faciliter l'équilibrage de l'appareil
Le corp central est constitué d'une cage tubulaire dans laquelle sont prévues les sangles destinées b maintenir le pilote
Selon une variante, les ressorts d'équilibrage sont prévus dans le cockpit
Les dessins annexés illustrent l'invention
La figure I représente de face le dispositif selon l'invention
La figure 2 représente en coupe, le dispositif du corp central
La figure 3 représent vue du dessous, la structure d'une des ailes
La figure 4 représente en perspective* une variante de la disposition des ressorts d'équilibrage
Le dispositif représenté sur la figure I comporte un corp central (I) ayant des disentiona suffisantes pour que le pilote puisse prendre place à l'intérieur . De chaque côté sont disposées les 2 ailes articulées (2) dont l'envergure est déterminée suivant les performances souhaitées , de 10 à I5 i. other I1 peddles a central part leaving an interior hollow sufficient for the pilot to take his place, the latter being held inside by straps leaving his feet and legs free. This, in order to allow him, at the start, to run to the ground to give a certain speed to the aircraft. Then, the pilot raises his feet to actuate the pedals controlling the flapping of the wings. During this maneuver, the wings of the aircraft will be kept blocked by a braking system in a slightly elevated position relative to the horizontal. The pilot unlocking the wings when he puts his feet on the pedals
According to a preferred embodiment, the wings have a variable span, increasing by about 1 / 6th each time there is a presaion on the pedals
Each wing is assisted in their movement by a spring adjusted so as to reduce to the nininua the effort that the pilot must provide to make the wings flap. This detail represents the essence of the invention
In the strong embodiment according to the attached figures, the soft-winged wings have a certain similarity with the bat wings.
Each wing being independent of each other. The rear plane of the wing of each wing is orientable along the central body, this orientation is carried out using 2 levers, left and right, within reach of driver's yias. It is done from top to bottom to facilitate the balancing of the device
The central body consists of a tubular cage in which are provided the straps intended to hold the pilot
According to a variant, the balancing springs are provided in the cockpit
The accompanying drawings illustrate the invention
Figure I shows the device of the invention from the front
Figure 2 shows in section, the device of the central body
Figure 3 shows a view from below, the structure of one of the wings
Figure 4 shows in perspective * a variant of the arrangement of the balancing springs
The device shown in Figure I has a central body (I) having sufficient disentiona for the pilot to take place inside. On each side are arranged the 2 articulated wings (2) whose span is determined according to the desired performance, from 10 to 15 i.
2 ressorts d'équilibrage (3) dont la tension est prévue réglable suivant le poids du pilote . 4 natures (ils) avec haubanage, sur lesquelles sont fixes les poulies de renvoi des cables (4) comandant les ailes
La figure 2 représente le corp de l'appareil en coupe, laissant voir le bras coulissant (5) sur lequel est fixée la pédale (6) et le levier (8) coiian dant le plan arriere de la voilure (7) et, la poulie de renvoi (I2) du cable de transsission (4)
La figure 3 représente l'aile (2) vue du dessous, et le palier coulissant (I0) permettant la variation de l'envergure de l'aile
La figure 4 représente la coupe en perspective d'une variante du dispositif des ressorts d'équilibrage (II) agissant sur le curseur (I4) fixé au bras coulissant des pédales (5) 2 balancing springs (3) whose tension is provided adjustable according to the weight of the pilot. 4 natures (they) with guying, on which are fixed the pulleys of return of the cables (4) controlling the wings
Figure 2 shows the body of the device in section, showing the sliding arm (5) on which is fixed the pedal (6) and the lever (8) coiian dant the rear plane of the wing (7) and, the return pulley (I2) of the transmission cable (4)
Figure 3 shows the wing (2) seen from below, and the sliding bearing (I0) allowing the variation of the span of the wing
Figure 4 shows the perspective section of a variant of the device of the balancing springs (II) acting on the slider (I4) fixed to the sliding arm of the pedals (5)
