Example Embodiment

[0017] Hereinafter, the present invention will be further described in detail with reference to specific embodiments in conjunction with the drawings.

[0018] In Figure 1: 1 is the body, 2 is the main wing, 3 is the engine, 4 is the propeller, 5 is the vertical tail, and 6 is the horizontal tail. The torque produced by the engine 3 installed on the body 1 or the main wing 2 is transmitted to the input shaft 10 of the clutch 9 installed in the body 1 through the transmission gear 8 (or transmission belt, chain, etc.). The clutch 9 engages the central transmission (or deceleration). The transmission (or reducer) 11 transmits the torque after the torque conversion to the end bevel gear 13 of the transmission shaft 12 (or transmission belt, transmission chain, hydraulic transmission mechanism, etc.) to the center of gravity of the aircraft or before and after the main wing 2. The shaft ends of the drive shaft 14 of at least two pairs of the propeller 4 are input to the bevel gear 15....

Abstract

This invention discloses one vertical lift plane, which relates to one aviator and to one inclined rotation fan or inclined channel fan pusher vertical plane, which comprises plane body, main wing, motor, pusher, vertical tail wing, level tail wing, lift rack and other device. The invention is characterized by the following: power from at least one motor is concentrated through central gear or decelerator through drive power system to distribute on machien gravity or main wing front and back. The left and right inclined axis end can pass level and vertical rotation to seaprte pusher front projection.

Description

technical field [0001] The invention relates to an aircraft, in particular to a vertical take-off and landing aircraft with tilting rotors or tilting ducted fan propellers. Background technique [0002] At present, there are U.S. V-22 and V-44 tilt-rotor aircraft about the invention of tilt-rotor or tilt-ducted fan propeller, and there is Chinese patent No. CN97202712.2—a vertical take-off and landing biplane. The V-22 uses a pair of tiltrotors mounted on the ends of the main wings, which are not stable enough for vertical take-off and landing. Page 16 of the 6th issue of "Aviation Knowledge" magazine in 2002 reported the V-44 tilt-rotor aircraft concept. It takes off and lands vertically, but the frontal projections of the front and rear rotors overlap, causing air vibration between the front and rear rotors, making its level flight performance worse than that of conventional aircraft; moreover, it uses a large number of engines, and any engine fails ...
