Wing of ornithopter and ornithopter

Abstract

The invention relates to a wing of an ornithopter and the ornithopter. The wing of the ornithopter comprises a wing body, wherein the airfoil section of the wing body is of a bow shape defined by an upper surface and a lower surface; a leading edge line and a trailing edge line of the wing body are curves respectively; and the distance between the leading edge line and the trailing edge line is gradually reduced and the thickness of the wing body is gradually reduced along the unfolding direction of the wing body. Through the technical scheme, the airfoil camber and thickness of the wing of the ornithopter and the distribution in the spanwise direction are changed, so that the wing is closer to the wing of a bird in appearance, the aerodynamic efficiency of the wing under the flutter condition is improved, and the effective load of the ornithopter is increased; when the ornithopter glides, more remarkable lift can be provided, and the wing is suitable for the ornithopter with a flutter-gliding mixed flight mode, so that the energy consumption can be obviously reduced, and the flight radius and the flight time can be increased.

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.
