Flapping-wing aircraft with eccentric wheels for pushing and pulling sliding boxes to do reciprocating linear motion to enable wing membranes to float

Abstract

The invention relates to a helicopter, and in particular relates to a flapping-wing aircraft with eccentric wheels for pushing and pulling sliding boxes to do reciprocating linear motion to enable wing membranes to float. A plurality of eccentric wheels are connected in series on a main transmission shaft, the initial positions of the adjacent eccentric wheels on the main transmission shaft are opposite up and down, an upper sliding box and a lower sliding box are arranged on the periphery of each eccentric wheel, transmission rods in up and down motion are connected above the upper sliding box and the lower sliding box through transmission rod connecting pieces, a pair of flapping-wing booms is symmetrically connected to the transmission rods in up and down motion, transmission rod sliding connection points are arranged at the joints of the flapping-wing booms and the transmission rods in up and down motion, flapping-wing pivots are arranged at the joints of the flapping-wing booms and tilting wing main arms, and flapping-wing soft wing membranes are arranged on the flapping-wing booms. The flapping-wing aircraft provided by the invention is larger in capacity, capable of flying farther, very simple in structure, easy to manufacture, safe and reliable.

Description

technical field [0001] The invention relates to an aircraft, in particular to an aircraft with an eccentric wheel push-pull sliding frame for reciprocating linear motion and an elegant flapping wing. Background technique [0002] In today's world, human beings have not produced large-scale orthopters that can fly freely and easily like insects or birds. Although there are miniature orthoplanes that successfully fly, they pale in comparison to insects and birds. At the same time, due to the flight mode, because the flapping wing cannot be too large, they cannot make a large flapping wing. Looking at the flight of creatures, there is nothing better than a dragonfly. It flaps its four wings at a fast and slow speed, flying and stopping, and going up and down. The freedom and ease are enviable. Dissecting the four wings of a dragonfly, it goes up and down in flight, naturally and steadily. Twisting the root of the wing arm from time to time is used to control the flight direc...

Problems solved by technology

Looking back at how clumsy human aircraft are, they consume a lot of energy, emit a lot of carbon dioxide, fly with smoke, and have an energy efficiency ratio of less than 50%.
