摘要:
The invention relates to a light plane comprising an engine arranged on the nose and provided with a tractor airscrew, and a cabin that is arranged behind the engine and is wide enough for two adjacent passenger seats. A central tube (1) with a 200 mm diameter extends forwards towards the engine and to the rear at least behind the front edge of the lateral rudder and elevator control. Everything else is constructed around said tube. A square profiled element (12) is transversally guided edgeways beneath the central tube (1) and is rigidly connected to the same in a positively engaged manner. An upwardly projecting tube bend (11) which arches over the length of the square profiled element is fixed to the rear side of the square profiled element (12) with the ends thereof. The level of a virtual plane cabin floor is defined above the square profile (12). The free space above said floor is orthorhombic: at least 190 cm long, at least 45 cm wide, and at least 40 cm high.

The invention relates to a hang glider comprising a wing (1), having a lower surface (2) and an upper surface (3), and walls (5) which are provided with openings (6) and which form wing sections. Rigid or semi-rigid bars and tubes (4) are mounted in the wing (1). The wing (1) is inflated, in operating position, by turbines (8) which are installed in the air inlets (7). A pilot (9) is positioned in a harness (10) which is connected to the tubes (4) by straps (11). The pilot can steer the hang glider by moving his/her body weight or by using the controls.

A hang glider (1) comprises a bearing tubular structure made of a longitudinal crossbar (4), a lower control trapeze (2) an upper vertical turret (6) and two wing spars (8), and a variable dihedral angle wing (10), which has its ends secured to the ends of the two spars and is secured to said lower control trapeze (2) through a plurality of cords (22a-28a,22b-28b) of which the lengths can be varied to lift or lower the wing, thereby varying the hang glider lift and speed during flight.

The invention concerns a rapidly releasable safety karabiner (1) comprising a fixed body (2) and a mobile element (3) hooked up to said fixed body by means of a transverse pin (4). The external forces applied to the karabiner are almost completely discharged onto support elements (12a,12b) set on the fixed body, constituted by two surfaces of contact that create a reaction substantially similar in magnitude and directed almost parallel to the applied load. Only the small remaining component of load bears on the transverse pin, sufficient to release the mobile part from the surfaces of support once the transverse pin is removed.

An ultra-light aircraft (10) of light-weight minimal contruction includes a rigid wing (12) from which a hang cage (15) is suspended by a main hinge assembly (13). Rotation of the wing (12) without pilot intervention induced by positive or negative wind gusts striking the wing (12) causes the angle of pitch between the wing and hang cage (13) to vary via the hinge so that the wing presents a relatively constant angle of attack to relative wind enabling the aircraft to be essentially stall free during flight. Twist and/or dihedral of the wing (12) is maintained by first and second sets of tensioned cables (103) or landing wires (105) connecting leading and trailing wing edges to a kingpost (100) projecting upward from the wing, and by first and second sets of flying wires (122) connecting the wing to the hang cage. Each first and second set of flying wires is a stress distributing arrangement including a pair of tubes (110) respectively connected at upper ends thereof to leading and trailing wing edges at lower ends to a plate (120) suspended between the wing and hang cage. A pair of tensioned cables in each set connect the plate to the hang cage (15). The point of attachement of the cables to the plate establishes a pivot point (125) located collinear with the hinge axis (32). The tubes (110) are free to rotate about the pivot point (125) during co-rotation of the wing (12) while maintaining proper dihedral and wing twist as well as tension transmitting bending stress acting on the wing (12) to the hang cage (15).

Dispositif pour assister le pilotage d'une aile volante notamment en modifiant la répartition de sa voilure. Ce dispositif comprend en particulier une platine (12) qui est montée en rotation sur la quille (8) selon un axe vertical, et qui coopère avec deux joues verticales (15, 16) pouvant tourner autour de cette quille (8). La cellule est suspendue à ces joues par l'intermédiaire d'un mât. Application dans le domaine des ailes volantes.
摘要:
57 Planeur ultra-léger appartenant à la catégorie dite des "ailes souples", caractérisé par au moins une zone de découplage (20) en sens transversal dans la voile (17). Dans une forme de réalisation la zone de découplage comporte une fente (21), s'étendant en sens longitudinal depuis le mât (16) de la structure, jusqu'au bord de fuite (19). La voile comporte des moyens (22) adaptés à maintenir sous tension la voile d'extrados et empêcher tout élargissement intempestif de la fente (21). L'invention concerne également une voile pour un tel planeur ultra-léger.

Aéronef caractérisé en ce qu'il est essentiellement constituté par un poste de pilotage (1) monté sur un châssis repliable (2) muni d'un train d'atterissage (3) sous forme de roulettes, par une voilure rotative (4) repliable munie de dispositifs (5) de conversion de la résistance de l'air suivant l'effet Coanda, par un mât télescopique (7) de support de la voilure rotative (4) et de modification de la forme de cette dernière, et par un dispositf (8) de commande de position de la voilure (4).
摘要:
A method and apparatus for shielding critical faster-moving upper wheel surfaces from headwinds reduces vehicle propulsive counterforces needed to countervail mechanically magnified upper wheel drag forces combined with drag forces on the apparatus itself. The apparatus includes various upper wheel fairings of FIGS. 1-6. Each fairing shields a critical primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging thereon.
