Co-rotating vertical take-off and landing membrane wing aircraft

Abstract

The invention discloses a co-rotating vertical take-off and landing membrane-wing aircraft. The aircraft comprises a fuselage, at least two rows of power spars are rotationally connected to the fuselage, and propellers are installed on the power spars. membrane wings rotationally connected with the fuselage are arranged between the adjacent power spars; folding angle adjusting mechanisms are arranged in the middles of the membrane wings; and the fuselage is provided with a linkage operation device which enables the membrane wings and the power spars to synchronously rotate relative to the fuselage. According to the co-rotating vertical take-off and landing membrane wing aircraft, the operation of switching between the lifting state and the flying state is simple, the speed range is large, and energy consumption is low.

Description

technical field [0001] The invention relates to the field of transportation equipment providing air transportation services, in particular to a co-rotating vertical take-off and landing membrane wing aircraft. Background technique [0002] There are many types of aircraft according to different classification methods, and they are mainly divided into two categories according to the take-off and landing methods: taxiing take-off and landing, and vertical take-off and landing. There are following deficiencies in some existing types of aircraft: [0003] 1) There is a basic fixed relationship among existing aircraft: fixed-wing aircraft must adopt the taxiing take-off and landing method, while propeller-wing aircraft need to adopt the vertical take-off and landing method. Rolling take-off and landing techniques are very difficult; [0004] 2) Fixed-wing aircraft have high requirements for take-off and landing sites.

AI Technical Summary

Problems solved by technology

[0003] 1) There is a basic fixed relationship among existing aircraft: fixed-wing aircraft must adopt the taxiing take-off and landing method, while propeller-wing aircraft need to adopt the vertical take-off and landing method. Rolling take-off and landing techniques are very difficult;

[0004] 2) Fixed-wing aircraft have high requirements for take-off and landing sites. Usually, a fixed airport is required for take-off and landing. The wing is subjected to huge forces (especially during take-off and landing), and the complex working conditions cause the wing structure to be complex and its own weight is difficult to reduce. ;

[0005] 3) It is difficult for a fixed-wing aircraft to land safely once it loses power or special circumstances (such as landing gear failure, forced landing before reaching the airport, etc.);

[0006] 4) Rotor-wing aircraft generally have huge rotors, and the noise and fuel consumption are very large during flight;

[0007] 5) Once a propeller-wing aircraft loses power or has a special situation, it is equally difficult to land safely;

[0008] 6) Existing manned aircraft are expensive, difficult to ensure safety and use and maintenance, and are difficult to popularize in ordinary people's homes like cars

[0009] 7) Since the area of ​​the lower surface of the wing is fixed when the existing aircraft is flying, the resistance increases sharply after the flight reaches a certain speed, the speed is difficult to further increase, and the energy consumption is large

[0010] 8) It is very difficult for the propeller-wing aircraft to switch between landing and entering the flight state
