flapping wing for orthopter

Abstract

The invention discloses a fluttering wing for an ornithopter, and belongs to the technical field of ornithopters. A fluttering wing framework is a bionic fluttering wing framework, the bionic fluttering wing framework comprises a wingspan-direction bending deformation structure and a wing-chord-direction distortion structure, and all skin supporting beams forming the bionic fluttering wing framework are made from elastic and deformable strip-shaped materials and comprise the main beam, the auxiliary beam and a plurality of wing rib beams; the skin part supported by the main beam forms a frontedge of the fluttering wing, the auxiliary beam is located behind the main beam, the wing rib beams are uniformly arranged in the wingspan direction, the main beam and the auxiliary beam are fixed together, and the skin part supported by the back ends of the wing rib beams forms a back edge of the fluttering wing; bent wingspan-direction piezoelectric fiber pieces respectively adhere to the main beam part and auxiliary beam part of the fluttering wing; distorted wing-chord-direction piezoelectric fiber pieces respectively adhere to all wing rib beam parts or partial wing rib beam parts of thefluttering wing. The fluttering wing has the advantages of being low in mass, flexible, efficient in flight and the like.

Description

technical field [0001] The invention relates to a flapping aircraft, in particular to a flapping wing for the flapping aircraft. Background technique [0002] The bionic flight of the flapping wing aircraft has a wide range of application prospects in national defense and military affairs, and has become the focus of research by various countries. In nature, birds control flight by controlling the flapping and deformation of wings. Birds actively adjust the deformation of wings according to different flight purposes to generate corresponding aerodynamic force, so that the flight is in the best flight state. Studies have shown that the aerodynamic force required by the bird-like aircraft is different under different flight conditions, so it is necessary for the flapping wings to produce controllable deformation according to the corresponding flight conditions to improve the efficiency and maneuverability of the flight. However, most of the existing fluttering wings do not ha...

AI Technical Summary

Problems solved by technology

However, most of the existing flapping wings do not have controllable active deformation capabilities, and the existing flapping wings cannot perform fine active and controllable deformations, and it is currently impossible to design flapping wings that can actively and complexly deform according to traditional mechanical design methods. Moving wings, or even if designed, the volume and mass are too large to be practical, thus affecting the flight performance of flapping wings
