Description

A miniature flapping wing device capable of controlling both wings separately

technical field

The utility model relates to the field of miniature flapping-wing aircraft, in particular to a miniature flapping-wing device capable of separately controlling two wings.

Background technique

Compared with fixed-wing aircraft, miniature flapping-wing aircraft has the characteristics of light weight, small size, strong maneuverability, high flight efficiency, and strong anti-reconnaissance capabilities, making it have a wide range of application prospects in both military and civilian fields. The flapping-wing aircraft is suitable for flying in a small space to complete tasks such as observation, reconnaissance, communication, and auxiliary rescue. Although micro-orthopting-wing aircraft imitate the wing movements of insects and birds, their size is significantly larger than that of insects or birds. Due to the limitation of technological development, micro-orthoping-wing aircraft cannot complete more complex flight movements like birds and insects.

Most of the existing micro-flapping-wing aircraft use a drive motor to drive one or more pairs of wings to achieve simultaneous flapping of the wings. This driving method is easy to control, and it is easier to obtain higher precision. It can also be used smoothly in the general flying environment. flight.

However, in a relatively complex flight environment, it is difficult for a micro-orthopting-wing aircraft to fly smoothly. If the two wings can be controlled separately, better flight can be achieved in a complex flight environment.
