Wings of flapping-wing aircraft and flapping-wing aircraft

Abstract

The present disclosure relates to a wing of a flapping-wing aircraft and the flapping-wing aircraft, wherein the wing of the flapping-wing aircraft includes a wing main body, and the airfoil section of the wing main body is configured as a curved bow formed by an upper surface and a lower surface; The leading edge line and the trailing edge line of the wing main body are curves respectively; along the span direction of the wing main body, the distance between the leading edge line and the trailing edge line gradually decreases, and the thickness of the wing main body gradually decreases. Through the above technical scheme, the camber and thickness of the airfoil of the flapping aircraft wing and its distribution along the span direction are changed, so that the shape of the wing is closer to that of a bird, and the flapping condition of the wing is improved. The lower aerodynamic efficiency increases the payload of the aircraft; when the aircraft is gliding, it can provide more significant lift, which is suitable for flapping-gliding hybrid flight mode flapping aircraft, which can significantly reduce energy consumption and increase flight performance. radius and flight time.

Description

technical field [0001] The present disclosure relates to the technical field of aircraft, and in particular, relates to a wing of a flapping-wing aircraft and the flapping-wing aircraft. Background technique [0002] The flapping-wing aircraft is a type of aircraft with bionic characteristics designed and manufactured by simulating the flapping flight of insects and birds. It has significant advantages such as light weight, strong maneuverability, low energy consumption, and strong concealment. fields have broad application prospects. [0003] The wing of a flapping-wing aircraft is a key component for generating lift and thrust, and its design is related to many aspects such as structural weight and aerodynamic efficiency, thus directly affecting the flight performance of the entire aircraft. Existing orthopter adopts skeleton film type wing mostly, and its basic structural form is that rigid skeleton is covered with flexible film. Although this thin-plate wing structure ...

AI Technical Summary

Problems solved by technology

Although this kind of thin-plate wing structure can have a certain degree of flexible deformation under the action of aerodynamic loads, its thrust and propulsion efficiency is low, and the payload is small, which is not conducive to the improvement of the flight performance of the aircraft.
