An orthopter that relies on changing the center of gravity for steering and its working method

Abstract

The invention discloses a flapping-wing aircraft capable of steering by changing center of gravity and a working method thereof. The flapping-wing aircraft comprises a basic assembly, spreading wing assemblies, a transmission assembly and a direction control assembly. The basic assembly comprises a mounting bracket and a landing gear; the spreading wing assemblies are symmetrically hinged to bothsides above the mounting bracket, and includes a primary spreading wing, a secondary spreading wing and a flap; the transmission assembly includes a gearbox disposed in the mounting bracket, a drive motor mounted at one end of the mounting bracket and connected with the gearbox in a transmission mode and a connecting rod mechanism mechanically connected with the gearbox and hinged to the spreadingwing assembly; and the direction control assembly is mounted at the end, away from the spreading wing assemblies, of the mounting bracket, and includes an eccentric turntable and a deceleration motorconnected with the eccentric turntable. The steering of the flapping machine is realized by changing the center of gravity, the weight of the flapping-wing aircraft is reduced, and it is ensured thata steering mechanism is not prone to being damaged.

Description

technical field [0001] The invention relates to the field of bionic organisms, in particular to an orthopter for steering by changing the center of gravity and a working method thereof. Background technique [0002] The orthopter refers to a heavier-than-air aircraft whose wings flutter up and down like the wings of birds and insects, also known as the thopter; when the wings flutter up and down, not only the fuselage generates lift, but also generates forward propulsion force. At the present stage, most of the flapping-wing aircraft on the market use the steering gear to pull the swing wing on the empennage mechanism to realize the steering of the fuselage, but this structure using the empennage to steer has the following disadvantages: First, the empennage structure is relatively complicated and the quality is relatively low. It is large, which increases the weight of the orthopter; second, the tail structure is exposed at the tail of the orthopter, and it is very easy to...
