DIS F0 SITIF ET PROCEDE DE PILOTAGE ET DE
PROPULSION POUR AERONEF A AILES ARTICULES SOUPLES
La présente invention concerne un aéronef à ailes battantes ou ornithoptère
Des ornithoptères ont déjà été constrtiitet certaines maquettes faisant appel à la technique de l'aile battante ont pu s'élever plus haut que leur point de départ uniquement grâce à la force de propulsion procurée par les
battements des ailes animées par un élastique.DIS F0 SITIF AND METHOD OF DRIVING AND
PROPULSION FOR FLEXIBLE ARTICULATED WING AIRCRAFT
The present invention relates to an aircraft with flapping wings or ornithopter
Ornithopters have already been constructed and some models using the flapping wing technique have been able to rise higher than their starting point solely thanks to the propulsive force provided by the
beating of the wings animated by an elastic band.
Ces appareils ne comportent pas de dispositif de pilotage.These devices do not include a piloting device.
Des appareils à ailes battantes rigides ou souples, motorisés ou non, de taille suffisante pour emporter un pilote ont déjà été construits, mais aucun n'a réussi à voler faute de moyen de propulsion et de pilotage simple et peu
couteux en poids.Rigid or flexible winged aircraft, motorized or not, of sufficient size to carry a pilot have already been built, but none has succeeded in flying for lack of propulsion and simple and little piloting.
expensive in weight.
Le dispositif selon l'invention comporte un fuselage dans lequel est aménagé un emplacement pour le pilote et une paire d'ailes souple, disposée de part et d'autre du fuselage. Les ailes sont rattachées au fuselage par un système cardan, qui peut être une pièce mécanique ou un bloc de caoutc-iuc et un compas.The device according to the invention comprises a fuselage in which is arranged a location for the pilot and a pair of flexible wings, arranged on either side of the fuselage. The wings are attached to the fuselage by a gimbal system, which can be a mechanical part or a block of rubber and a compass.
le cardan est disposé entre le fuselage et la base du longeron de l'aile, et le compas est placé entre le fuselage et le bord de fuite de l'aile. La combinaison du cardan et du compas permet à l'aile de débattre de haut en bas et d'avant en arrière.the gimbal is placed between the fuselage and the base of the wing spar, and the compass is placed between the fuselage and the trailing edge of the wing. The combination of gimbal and compass allows the wing to debate up and down and back and forth.
Le pilote provoque le mouvement de bas en haut avec ses jambes et d'avant en artère avec ses bras.The pilot causes the movement from bottom to top with his legs and from front to artery with his arms.
Les dessins annexés illustrent l'invention.The accompanying drawings illustrate the invention.
La figure 1 représente l'invention vue de dessus
La figure 2 représente l'invention vue de coté
La figure 3 représente une perspective cavalière de l'invention
En référence à ces dessins, le fuselage (1) comporte: - 2 ailes (2) disposées symétriquement par rapport à l'axe longitudinal de part et d'autre du fuselage. Gracie aux cardans (3) les ailes peuvent se déplacer d'avant en arrière et de haut en bas.Figure 1 shows the invention seen from above
Figure 2 shows the invention from the side
FIG. 3 represents a perspective view of the invention
With reference to these drawings, the fuselage (1) comprises: - 2 wings (2) arranged symmetrically with respect to the longitudinal axis on either side of the fuselage. Thanks to the gimbals (3) the wings can move back and forth and up and down.
Les compas (4) permetent le mouvement de bas en haut grace à une rotule (5), mais limitent le changement d'incidence des embases des ailes.The compasses (4) allow movement from the bottom up thanks to a ball joint (5), but limit the change in incidence of the wing bases.
-1 empennage (6) destiné à stabiliser et diriger l'appareil en vol plané -1 siège pilote (7) - 2 palonniers (8) couplés par une biellette (9) à un renvoi(10), lui-même
couplé par une autre biellete (11) au longeron conique (12) de chaque aile (2) de telle façon que l'extension des jambes du pilote provoque l'abaissée de l'aile et leur repliage provoque la remontée de l'aile.-1 tailplane (6) intended to stabilize and steer the aircraft in gliding flight -1 pilot seat (7) - 2 lifting beams (8) coupled by a link (9) to a return (10), itself
coupled by another link (11) to the conical spar (12) of each wing (2) so that the extension of the pilot's legs causes the wing to be lowered and their folding causes the wing to rise.
- la position du renvoi (10) est choisie de telle façon que par la gravité l'aile avance quand elle s'élève et recule quand ele s'abaisse
Une poignée permet au pilote d'agir sur l'avance ou le reculade l'aile, agissant par variation du centrage sur le tangage. Le pilotage en roulis et en
lacet induit est provoqué par l'avancée de l'aile extérieur au virage et le recule de l'autre, intérieure au virage. Le pilotage en roulis et en lacet peut également être obtenu par différence de pression sur les deux palonniers.- the position of the return (10) is chosen in such a way that by gravity the wing advances when it rises and recedes when it lowers
A handle allows the pilot to act on the advance or retreat of the wing, acting by varying the centering on the pitch. Steering in roll and
induced yaw is caused by the advancement of the wing outside the turn and backward on the other, inside the turn. Roll and yaw control can also be obtained by pressure difference on the two rudder pedals.
Les deux palonniers peuvent fonctionner couplés ensemble ou séparément
Afin de limiter l'effort dans les jambes du pilote, un ressort en caoutchouc (14) relie la base du fuselage (1) au longeron de l'aile (2); un cliquet (15) permet d'imobiliser l'aile en position médiane pour
l'atterrissage et le décollage.The two lifting beams can work together or separately
In order to limit the effort in the legs of the pilot, a rubber spring (14) connects the base of the fuselage (1) to the spar of the wing (2); a pawl (15) allows to immobilize the wing in the middle position to
landing and takeoff.
Chaque aile est constituée par:
- un longeron à flexibilité progressive de telle façon que l'extrémité la plus éloignée du corps de l'appareil soit la plus souple - un couple rigide (19) solidaire de l'embase du longeron (12)
- des couples (16) à flexibilité progressive de telle façon que l'extrémité correspondant au bord de fuite d l'aile soit la plus souple.Each wing is made up of:
- a beam with progressive flexibility so that the end furthest from the body of the appliance is the most flexible - a rigid torque (19) secured to the base of the beam (12)
- Torques (16) with progressive flexibility so that the end corresponding to the trailing edge of the wing is the most flexible.
- un entoilage en tissu (17) - un "Karmann" (18) en tissu élastique rendant étanche à l'écoulement de l'air la liaison entre le fuselage et les ailes.- a fabric interlining (17) - a "Karmann" (18) in elastic fabric making the connection between the fuselage and the wings airtight.
La moitié extérieure de l'aile la plus souple correspondant aux rémiges chez
l'oiseau, a un fonctionnement propulsif pendant le battement de haut en
bas, à la manière de la palme d'un nageur.The outer half of the most flexible wing corresponding to flight feathers in
the bird, has a propulsive functioning during the beat up and
low, like a swimmer's palm.
La moitie intérieure, la plus près du corps de la machine fonctionne comme
une aile d'avion animée d'un mouvement de bas en haut. Compte tenu du fait que sa vitesse horizontale est beaucoup plus grande que sa vitesse verticale, l'incidence reste toujours largement positive et permet la sustentation aussi bien pendant l'abaissée que pendant la remontée de l'aile.The inner half, closest to the body of the machine works as
an airplane wing animated from bottom to top. Given the fact that its horizontal speed is much greater than its vertical speed, the incidence always remains largely positive and allows the lift both during the lowering and during the ascent of the wing.
Le changement d'incidence se fait automatiquement par composition entre la résistance de l'air et la déformation des parties souples de l'aile.The change of incidence is done automatically by composition between the air resistance and the deformation of the flexible parts of the wing.
- Le pilote peut adopter une position assise jambes allongées en avant ou
une position allongée sur le ventre jambes allongée vers l'arrière.- The pilot can adopt a sitting position with legs stretched forward or
a lying position on the belly legs stretched backwards.
L'invention peut être également motorisée. La puissance disponible étant alors non limitée, le vol vertical est possible.The invention can also be motorized. Since the available power is not limited, vertical flight is possible.
L'invention est destinée à voler, à pratiquer les sports de l'air et dans sa version motorisée à transporter des personnes ou des charges.The invention is intended to fly, to practice air sports and in its motorized version to transport people or loads.
- Selon les principes décrits ci-dessus, le nombre de paires d'ailes sur le
fuselage n'est pas limité. - According to the principles described above, the number of pairs of wings on the
fuselage is not limited.
