Title (EN) HYBRID AIRCRAFT
(FR) AERONEF HYBRIDE
Abstract:
(EN) A hybrid aircraft is taught having VTOL, R-VTOL and S-STOL capabilities. The aircraft has a lifting body hull (1) and four wing sections (20) arranged in tandem which are pivotally moveable about their neutral axis. Each wing section has mounted thereon a pivotal propeller-rotor (21) assembly for providing thrust substantially in a range between horizontal and vertical. The wings and propellers are integrated to the hull by an outrigger designed to be very stiff and to distribute forces from the wings and propellers to the hull. The hull is shaped to provide aerodynamic lift in an airstream and to facilitate construction by minimizing the number of panels of differing curvature required. The hull is formed of a pressure tensioned frame covered with semi-rigid panels, a lower cladding frame and bow and stem cladding nose cones. The semi-rigid panels covering the frame are formed of gas-tight and abrasion resistant laminate material and are connected to the frame by means of an interface rib and latch system. The frame is formed of a plurality of curved elongate segments arranged in series orthogonal to the long axis of the hull and connected by means of torsion members. A turbo-electric drive system can be used to drive the aircraft. An advanced hybrid aircraft is also described having about 8 to 12 high speed fans in place of the propeller-rotors.
(FR) La présente invention concerne un aéronef hybride ayant des capacités ADAV, ADAV-R (roulage) et ADAC-S (super-court ou extra-court). Cet aéronef a une coque (1) principale sustentatrice et quatre tronçons d'ailes (20) disposés en tandem et pouvant pivoter autour de leur axe neutre. Sur chaque tronçon d'aile est monté un rotor-hélice (21) pivotant, qui sert à fournir une poussée sensiblement dans un domaine compris entre l'horizontale et la verticale. Les ailes et les hélices sont reliées à la coque par un bras étudié pour posséder une grande rigidité et pour transmettre à la coque les forces provenant des ailes et des hélices. La forme de la coque est telle qu'elle fournisse une portance aérodynamique dans un écoulement d'air et qu'elle facilite la construction grâce à la réduction au minimum du nombre de panneaux nécessaires ayant des courbures différentes. La coque est constituée par une ossature mise sous tension par pression et couverte de panneaux semi-rigides, une ossature inférieure pour revêtement et des cônes de nez avant et arrière pour revêtement. Les panneaux semi-rigides couvrant l'ossature sont faits d'une matière feuilletée, étanche aux gaz et résistant à l'abrasion, et ils sont reliés à l'ossature au moyen d'un système de nervures d'interface et de verrous. L'ossature est constituée par un certain nombre de segments allongés courbes, disposés en séries perpendiculaires à l'axe longitudinal de la coque, et reliés par des organes de torsion. On peut utiliser un système d'entraînement turboélectrique pour propulser cet aéronef. L'invention concerne aussi un aéronef hybride avancé, équipé d'environ 8 à 12 soufflantes à grande vitesse au lieu des hélices-rotors.
