Problems solved by technology

However, the flapping motion of the two wings of the flapping-wing micro-aircraft is not completely symmetrical, which brings great problems to size optimization and subsequent control, which seriously affects the performance of the aircraft.
In addition, it is difficult to further improve the structure of the aircraft, so it is difficult to complete various complex tasks in the future

Abstract

The invention discloses a mummingbird-wing-flapping-imitating micro air vehicle (MAV) which belongs to a biomimetic MAV field. The MAV comprises: a frame, a reduction gear set, a motor, a transmission mechanism, a parallel shaft structure, and a pair of wings. The reduction gear set, the motor, and the parallel shaft structure are directly arranged on the frame. The transmission mechanism is arranged between the reduction gear set and the parallel shaft structure, and is used for converting continuous rotation outputted by the reduction gear set into reciprocative rotation of the parallel shaft structure. The pair of wings is arranged on the parallel shaft structure, such that self flapping movements can be realized. The pair of wings and other parts form a complete wing-flapping MAV. According to the invention, the flapping movements of the two wings are completely symmetric, such that influences of vibration on the performance of the MAV are greatly reduced, and control difficulty of the MAV is reduced. Also, the MAV provided by the invention has advantages of simple and reasonable structure and convenient processing. The MAV can easily be improved, such that complicated tasks can be completed.

Description

technical field [0001] The invention relates to the technical field of a bionic micro-aircraft, in particular to a hummingbird-like flapping wing micro-aircraft. Background technique [0002] Micro-aircraft is a kind of aircraft that can measure no more than 15cm in any direction. It has a very wide range of uses in military, industrial and civilian fields-it can complete many tasks such as search and rescue, investigation, and surveillance. With the advancement of science and technology, micro-aircraft is also developing in a more stable, more flexible and more energy-saving direction. [0003] For micro-aircraft, the most common flight modes are fixed-wing flight, rotary-wing flight and flapping-wing flight. Micro-aircraft using the first two flight mechanisms have already appeared, but it cannot be denied that these two flight methods have inherent limitations in the field of micro-aircraft. For example, fixed-wing micro-aircraft face the problem of instability under wi...
