Cross-medium aircraft with X-shaped aerodynamic layout based on cycloid propellers

Abstract

The invention provides an X-type aerodynamic layout cross-medium aircraft based on cycloid propellers. The aircraft comprises an aircraft body, a rotatable folding wing, a cycloid propeller and a rotatable folding device, the aircraft body is connected with a fixed wing, the rotatable folding device is embedded in the fixed wing, the other end of the rotatable folding device is connected with the rotatable folding wing, the cycloid propeller is coaxially connected with the rotatable folding wing, and the cycloid propeller is coaxially connected with the rotatable folding wing. Steering engines used by the cycloid propellers are embedded in the rotary folding wings, the cycloid propellers are used for providing power for the aircraft and changing the direction in the sailing process, the number of the fixed wings is at least four, and the number of the rotary folding wings, the number of the cycloid propellers and the number of the rotary folding devices are matched with the number of the fixed wings. And the fixed wings are uniformly distributed in four quadrants of a coordinate system drawn by taking the aircraft main body as an original point to form an X shape. By using the cycloid propellers, the problem of design redundancy of a cross-medium aircraft can be well solved, the self weight is reduced, and the effective load capacity is increased.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a cross-medium aircraft based on an X-shaped aerodynamic layout of a cycloid propeller. Background technique [0002] As a kind of aircraft that can realize the operation in the water-air amphibious environment, the trans-medium aircraft combines the advantages of the navigation in the two media of the submarine and the aircraft. It has a high speed when navigating in the air; when navigating underwater, it avoids the detection of enemy ships and has better concealment. It can switch and maneuver quickly in different media, so as to realize concealment, reconnaissance, defense penetration and communication relay. Great military potential. Although the "Cormorant" submarine-launched UAV designed by Lockheed Martin of the United States can achieve cross-media, it can only launch rockets out of water and splash down on the water for recovery, and cannot navigate in different media...

Problems solved by technology

Although the "cormorant" submarine-launched drone designed by Lockheed Martin of the United States can achieve cross-media, it can only launch rockets out of water and splash down on the water for recovery, and cannot navigate in different media.

At the same time, most other trans-media vehicles are designed based on the jet propulsion method, the propulsion device is heavy, and the waterproof treatment is complicated, which is relatively redundant
