摘要:
A hybrid propulsion aircraft is described having a distributed electric propulsion system. The distributed electric propulsion system includes a turbo shaft engine that drives one or more generators through a gearbox. The generator provides AC power to a plurality of ducted fans (each being driven by an electric motor). The ducted fans may be integrated with the hybrid propulsion aircraft's wings. The wings can be pivotally attached to the fuselage, thereby allowing for vertical take-off and landing. The design of the hybrid propulsion aircraft mitigates undesirable transient behavior traditionally encountered during a transition from vertical flight to horizontal flight. Moreover, the hybrid propulsion aircraft offers a fast, constant-altitude transition, without requiring a climb or dive to transition. It also offers increased efficiency in both hover and forward flight versus other VTOL aircraft and a higher forward max speed than traditional rotorcraft.
摘要:
An aircraft lifting surface (43, 73) attached to the rear or frontal end (11, 10) of the aircraft fuselage with a variable sweep angle α in an inboard part (45, 75) and with a constant sweep angle α 1 in an outboard part (47, 77) is provided. The aircraft lifting surface can be for example a horizontal tail plane (43) or a vertical tail plane attached to the rear end fuselage (11) or a canard (73) attached to the frontal end fuselage (10).
摘要:
A superagile tactical fighter aircraft has articulatable air inlets (13), articulatable exhaust nozzles (14), highly deflectable canard surfaces (19), and control thruster jets (22) located around the nose (11) of the fuselage, on the top and bottom surfaces of the propulsion system near the exhaust nozzles, and on both sides of at least one vertical tail (20). The superagile aircraft attains supernormal flight by articulating the air inlets and exhaust nozzles, deflecting the canard surfaces, and vectoring the thruster jets. Supernormal flight may be defined as flight at which the superagile aircraft operates at an angle of attack much greater than the angle of attack which produces maximum lift. In supernormal flight, the superagile aircraft is capable of almost vertical ascents, sharp turns, and very steep descents without losing control.
