Horizontal flapping wing low-altitude aircraft

Abstract

The invention relates to the technical field of aircrafts, in particular to a horizontal flapping wing low-altitude aircraft which comprises a rack, a nose is arranged at the front end of the rack, apropelling device is arranged at the tail end of the rack, and a first flight unit, a second flight unit and a third flight unit are sequentially arranged between the nose and the propelling device. The second flight unit is arranged in the center between the first flight unit and the third flight unit and arranged at the gravity center of the rack, a control circuit is arranged on the rack, the first flight unit, the second flight unit and the third flight unit are controlled through the control circuit, and the first flight unit and the third flight unit ascend and descend synchronously. Andthe second flight unit performs up-and-down staggered lifting action. By the adoption of the structural arrangement, under the matching action of the first flight unit, the second flight unit and thethird flight unit, lift force is generated to achieve takeoff of the aircraft, advancing is achieved under the action of the propelling device, and the aircraft is compact in structure, low in cost and capable of achieving the low-altitude flight effect.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a flapping-wing low-altitude aircraft. Background technique [0002] The lift device of an aircraft is a device based on aerodynamics. According to the structure, it can be divided into fixed wings and rotors. Fixed wing aircraft generally have a fuselage and symmetrically arranged fixed wings, which are powered by propellers to obtain greater flight speeds. and mobility. The principle of flight is that there is a relative speed between the fixed wing and the air, and the air interacts with the sides of the fixed wing to generate lift so that the aircraft obtains flight capability. The disadvantage of fixed-wing aircraft is that it cannot hover in the air, and needs to taxi on the runway to take off or land and support the construction of airport facilities. A rotorcraft such as a helicopter is characterized in that it does not need a runway when it takes off and can hover in ...

AI Technical Summary

Problems solved by technology

Its advantage is that it has lower requirements on the take-off runway but still needs to glide distance, and it cannot hover in the air. The application range is limited
