Wings and transmission mechanism of ornithopter

Abstract

The invention discloses wings and a transmission mechanism of an ornithopter. Each of the wings of the ornithopter is divided into an inner wing panel, a middle wing panel and an outer wing panel; the transmission mechanism drives a crankshaft through a motor; the crankshaft drives a linkage; one end of a stator passes through a gap at the middle of the linkage, and the other end of the stator is fixed onto a body; the front end of the linkage is connected with certain ends of inner sides of inner wing panel rear skeletons respectively; the inner wing panel rear skeletons pass through the body outwards and take the body as a pivot; the certain ends of outer sides of the inner wing panel rear skeletons are connected with lower end vertexes of inner sides of rectangular skeletons, which can be changed into rhombuses, of the middle wing panels; certain ends of inner wing panel front skeletons are fixed on the body, and the other ends of the inner wing panel front skeletons are connected with upper end vertexes of the inner sides of the rectangular skeletons, which can be changed into the rhombuses, of the middle wing panels, and under the combined action of the inner wing panel front skeletons and the inner wing panel rear skeletons, forms can be changed continuously; outer wing panel shape-preserving wings are connected with the outer sides of the middle wing panel through hinges, and angle limitation devices on the hinges of the outer wing panel are used for limiting the oversize lifting angle of the outer wing panel; through adoption of the way, the movement of the ornithopter can present the states of birds in a flying process.

Description

technical field [0001] The invention belongs to the field of general aviation and relates to a wing and a transmission mechanism of an orthopter. Background technique [0002] Nowadays, the world pays more attention to the development of orthopter. Many countries have developed various orthopeds, some of which imitate the flying methods of insects, and some imitate the flying methods of birds. However, due to various reasons, only Being able to imitate some of the functions and movements of the original creature does not fully reflect the advantages of flapping-wing flight. The main reason is that the essence of flapping-wing flight is not well understood, and it only imitates part of the original creature's movements one-sidedly. , Like the robotic bird developed by some institutions, it can only show that when the wings are raised, the outer wing section is bent downward. Although flapping flight has been achieved, it still cannot reflect the aerodynamic advantages of flap...
