Title:
AIRCRAFT AND METHOD FOR REALIZING VERTICAL TAKE-OFF AND LANDING AND HORIZONTAL FLIGHT USING BOTTOM-DRIVE FLAPS TILTED IN SECTIONS
Document Type and Number:
WIPO Patent Application WO/2020/177739
Kind Code:
A1
Abstract:
An aircraft realizing vertical take-off and landing and horizontal flight using bottom-drive flaps tilted in sections. A large-area plate-shaped wing is used, and movable strip-shaped flaps (4; 8; 9) and fixed strip-shaped flaps (5) are alternately arranged on the wing in the transverse direction, several driving devices (3) are arranged side by side below each section of the movable strip-shaped flaps (4; 8; 9), the movable strip-shaped flaps (4; 8; 9) and the driving devices (3) are fixed as a whole and are tilted around a sheet fuselage (6) by means of a movable strip-shaped flap rotary shaft (17), and the tilt angle can reach 95° or more, so that the movable strip-shaped flaps (4; 8; 9) can be tilted to be horizontal so as to be combined with the fixed strip-shaped flaps (5) to form a whole horizontal wing to adapt to horizontal flight, and can also be tilted downwards to open strip-shaped air inlet holes so as to realize vertical take-off and landing, and to be able to fly backwards in a hovering state. Also included is a method for realizing vertical take-off and landing and horizontal flight of an aircraft using bottom-drive flaps tilted in sections. A large-area plate-shaped wing is transversely dividing into several sections of movable strip-shaped flaps (4; 8; 9) and fixed strip-shaped flaps (5), the fixed strip-shaped flaps (5) are rigidly connected to a fuselage, and the movable strip-shaped flaps (4; 8; 9) are connected to the fuselage by means of transverse hinges, so that the movable strip-shaped flaps can be tilted longitudinally; and the lower parts of the movable strip-shaped flaps (4 ;8; 9) are fixedly connected to driving devices (3), and the driving devices in the sections are connected in parallel, so as to achieve a smooth change of the flight mode.
