Bionic flapping wing aircraft with adjustable flapping amplitude angle

Abstract

The invention relates to a bionic flapping wing aircraft with an adjustable flapping amplitude angle. The bionic flapping wing aircraft with the adjustable flapping amplitude angle comprises an aircraft body, a flapping mechanism, two wing mechanisms, a tail wing mechanism, a microprocessor and a wireless communication module; the flapping mechanism is mounted at the head part of the aircraft body; the two wing mechanisms are mounted on the two sides of the flapping mechanism in a bilaterally symmetric manner; and the tail wing mechanism is mounted at the tail part of the aircraft body. Duringtaking off, a first motor, a second motor and a third motor of the flapping mechanism are started to work to provide greater power to be beneficial for taking off; after takeoff is finished, the third motor is enabled to stop rotating, and the first motor and the second motor continue to rotate; and meanwhile, ground working personnel can change rotating angles of the first motor and the second motor by operating a remote controller so as to finish once flapping amplitude angle adjustment so as to reduce the flapping amplitude angle; and therefore, the power demand is reduced to be beneficialfor saving energy and reducing flying cost.

Description

technical field [0001] The invention relates to the technical field of aircraft, in particular to a bionic flapping-wing aircraft with adjustable flapping amplitude angle. Background technique [0002] A flapping-wing aircraft refers to an aircraft that generates lift and forward force through the active movement of the wings like a bird. The flapping-wing aircraft flies by flapping its wings during flight. Whether it is in the field of military reconnaissance or civilian disaster relief, it has very broad application prospects. [0003] When the wing of the bionic flapping-wing aircraft swings to the upper and lower limit positions, the angle between it and the horizontal plane is called the upper flapping amplitude angle, the lower flapping amplitude angle, the upper flapping amplitude angle and the lower flapping amplitude respectively. The sum of the angles is called the flutter amplitude angle. [0004] At present, many mechanical designs have been proposed for bionic...

AI Technical Summary

Problems solved by technology

If the flapping amplitude angle is fixed, the flapping amplitude angle is fixed after take-off and during take-off, the power required is large, the cost is high, and it is not conducive to adapting to various natural environmental changes such as strong winds and air currents.
