Problems solved by technology

Because it is combined with a fixed wing, the external disturbance is similar to that of a tiltrotor, and the disturbance coefficient is much larger than that of a simple multi-rotor, and the controllability is greatly reduced

Embodiment Construction

[0035] specific implementation

[0036] as attached Figure 1-2 As shown, the technical implementation mode adopts the following technical scheme: the fixed wing 2 is arranged in the middle of the fuselage 1, the aileron 8 is arranged on the power short wing 4, the power short wing 4 is arranged at both ends of the fixed wing 2, and the fuselage is arranged with Vertical empennage 6, horizontal empennage 3, landing gear 7, fuselage 1 top tandem is arranged with main lift rotor group 5.

[0037] As preferably, the main lift rotor group 5 cruises in vertical take-off and landing, hovering, and helicopter modes, and the forward flight of the autogyro is preferred, and the aerodynamic design is carried out.

[0038] Preferably, the main lift rotor group 5 adopts a tandem layout and rotates in opposite directions. mutually overcome the reverse torque.

[0039] As preferably, power short wing 4 is preferably carried out aerodynamic design with high-speed forward flight.

Abstract

The invention relates to a composite vertical take-off and landing (VTOL) efficient and high-speed aircraft. The invention provides a composite tilting wing tandem autorotation double-rotor aircraft.Two pairs of main lift rotor sets 5 are longitudinally arranged on the upper portion of an aircraft body 1, a fixed wing 2 is arranged in the middle of the aircraft body 1, two auxiliary power short wings 4 are arranged at the two ends of the fixed wing 2, ailerons 8 are arranged on the fixed wing 2, and parallel empennages 3, vertical empennages 6 and undercarriages 7 are arranged on the aircraftbody 1. The aerodynamic layout design of the composite tilting wing tandem autorotation double-rotor aircraft avoids the technical defects of the existing composite and tilting aircrafts, the tandemarrangement of the main lift suspended wings is adopted, and the rotor design defines the rotor group and the tilting power short wings according to the aerodynamic requirements of vertical take-off and landing, hovering and autorotation rotor mode cruising. The loading efficiency of the aircraft is higher than that of an existing composite helicopter, an existing tilt rotor aircraft and an existing composite multi-rotor aircraft.

Description

technical field [0001] The invention relates to a composite vertical take-off and landing (VTOL) high-efficiency and high-speed aircraft. Background technique [0002] Existing fixed-wing aircraft can fly forward at high speed, but they rely on runways for takeoff. With stall speed, no vertical take-off and landing (VTOL), hovering. Helicopters have vertical take-off and landing capabilities, can hover in the air, and are not dependent on the airport, but they cannot fly forward at high speed and efficiently. The research and development of aircraft with vertical take-off and landing capabilities, hovering in the air, and high-speed and efficient forward flight has always been the direction of the aviation industry. [0003] Representative models are: composite Sikorsky X2, S-97, SB-1, Eurocopter X3. There are V-22 and V-280 of Bell Company, X-18 of Hiller Company and so on. The stalled ones are: NASA's M85, Modus' disc-wing aircraft, and Boeing's CR / W. The multi-rotor ...
