Free semi-rotating flapping rotor device

Abstract

The invention discloses a free half-rotating type flapping rotor device which comprises a supporting assembly, a rotating assembly, a driving assembly, a rotating wheel assembly and a rotor wing assembly, the supporting assembly, the rotating assembly, the driving assembly, the rotating wheel assembly and the rotor wing assembly are in linkage fit, and the rotating assembly is driven by the driving assembly to rotate. A fact that the revolution main shaft of the flapping rotor device drives the rotating arm and the revolution main shaft to perform revolution can be realized. Due to the fact that the first rotating wheel is fixed to the supporting assembly, the second rotating wheel and the autorotation main shaft are coaxially arranged and fixedly connected, and the first rotating wheel and the second rotating wheel are connected through the chain, it can be achieved that in the revolution process of the flapping rotor wing device, the second rotating wheel can drive the autorotation main shaft to autorotate, and the inner diameter ratio of the first rotating wheel to the second rotating wheel is 1: 2, so that the autorotation main shaft can autorotate by 180 degrees when revolvingaround the revolution main shaft by 360 degrees, namely, the free half-rotation type operation of the flapping rotor device is realized.

Description

technical field [0001] The invention relates to the technical field of aircraft, and more specifically relates to a free half-rotation flapping rotor device. Background technique [0002] The flapping-wing aircraft is a flying device designed to imitate the flapping motion of insects or birds. The flapping-wing aircraft mainly relies on the flapping of the blades to generate lift, which can provide a large lift for the aircraft. The flapping-wing aircraft has vertical take-off and landing, hovering, Compared with fixed-wing and rotary-wing aircraft, flapping-wing aircraft has many advantages such as simple structure, light weight, low cost, and high efficiency. If flapping wing flight technology and rotor flight technology can be combined, it will not only have the advantages of vertical lift and hovering in the air that rotorcraft and helicopters have, but also realize that the aircraft consumes less energy during flight, is easy to control, and Low cost and other advantag...

AI Technical Summary

Problems solved by technology

[0003] In recent years, although there have been some technologies that combine flapping wings and rotors, that is, by using the flexible deformation of the flapping wings, the upward lift and forward thrust are generated when the flapping wings flap, and the antisymmetrical thrust forms a force couple at the same time, driving The flapping wing performs self-driven rotation, and the circumferential motion speed generated by the rotation can increase the lift, so as to achieve the purpose of increasing the overall lift. However, it has been found through experiments that the current flapping rotor device cannot provide enough lift for the aircraft. The ratio to the weight of the structure is very low, and the ability to take off normally has not been achieved

It can be seen that the existing flapping rotor devices often have disadvantages such as complex structure, bulky body, poor stability, difficult manufacturing design and high cost. These technical defects greatly limit the rapid development of flapping rotor devices
