Vertical and horizontal dual-purpose aircraft based on tilting power

Abstract

The invention belongs to the technical field of aviation aircrafts, and particularly relates to a vertical and horizontal dual-purpose aircraft based on tilting power. The vertical take-off and landing aircraft comprises a fuselage, two main wings, two front canards, a vertical empennage, N tilting ducted fans, an embedded lift ducted fan and an undercarriage. The vertical take-off and landing aircraft adopts a canard layout and a lift / thrust / control integrated power system, can realize the state conversion from vertical flight to horizontal flight, can take off and land in a smaller space, and is flexible to deploy. The power is separated from the wings, the canard layout is adopted, the aspect ratio can be effectively increased, the lift-drag ratio can be improved, and compared with a common vertical take-off and landing aircraft, the aircraft has the advantages of being high in voyage and low in energy consumption and has huge development prospects in the fields of aerial reconnaissance, surveying and mapping, monitoring and the like.

Description

technical field [0001] The invention belongs to the technical field of aviation aircraft, in particular to a vertical and horizontal dual-purpose aircraft based on tilting power. Background technique [0002] The fixed-wing aircraft has a long range and a large payload, but due to the need for rolling during take-off and landing, it has high requirements on the take-off and landing site, which limits its application range. [0003] Conventional helicopters generate lift through the rotors and realize vertical take-off and landing, thus getting rid of the limitations of the take-off and landing site and greatly expanding the usable scenarios of the aircraft. a wide range of missions. [0004] Vertical take-off and landing aircraft have the advantages of helicopters and fixed-wing aircraft at the same time. For a long time, many configuration schemes have been proposed at home and abroad, such as the V-22 "Osprey" in the United States. Although it realizes the combination of...

AI Technical Summary

Problems solved by technology

For a long time, many configuration schemes have been proposed at home and abroad, such as the American V-22 "Osprey". Although it realizes the combination of vertical take-off and landing and horizontal flight, it also has some problems, such as power failure during the transitional flight phase. Poor stability, severe aerodynamic interference between the rotor and the wing leads to low rotor efficiency, excessive pressure on the wing by the power system limits the application of large aspect ratio wings, large diameter and exposure of the rotor affect safety, and the control of transitional flight phases is complex and difficult to control high problem
