Flapping rotor wing device with shaft wings operating in coplanar manner in ascending vertical operation

Abstract

The invention discloses a flapping rotor wing device with coplane operation of a descending shaft wing in ascending vertical operation, which comprises a support assembly, a rotating assembly, a driving assembly, a rotor wing assembly and a transmission assembly, and is characterized in that the supporting assembly, the rotating assembly, the driving assembly, the rotor wing assembly and the transmission assembly are matched in a linkage manner, so in the descending process of the rotor wing assembly in the flapping rotor wing device, the rotor wing surface of the rotor wing assembly driven bythe second driving motor is always parallel to the axis of the rotating arm, and in the ascending process of the rotor wing assembly, the rotor wing surface of the rotor wing assembly driven by the second driving motor is always perpendicular to the horizontal plane; force counteracted with lifting force is prevented from being generated in the ascending process of the rotor wing assembly, so that the flapping rotor wing device provides continuous and stable lifting force for the aircraft through revolution and autorotation of the autorotation main shaft, and then stable take-off and hoveringof the aircraft are achieved.

Description

technical field [0001] The present invention relates to the field of aircraft technology, and more specifically relates to a flapping rotor device that runs vertically in the upward direction and runs coplanarly with the shafts in the downward direction. 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 ...

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
