Miniature insect-like double-rotation flapping wing air vehicle

Abstract

The invention relates to a miniature insect-like double-rotation flapping wing air vehicle. The miniature insect-like double-rotation flapping wing air vehicle comprises a rack, a flapping-wing rotary transmission system, a left-side front-rear flapping system, a right-side front-rear flapping system and a tail-wing system, wherein a motor b drives a left-side front flapping wing, a left-side rear flapping wing, a right-side front flapping wing and a right-side rear flapping wing to flap at high frequency by a gear b, a gear c, a worm, a front turbine, a rear turbine, a front two-end corner shaft and a rear two-end corner shaft. A motor a drives the left-side front flapping wing, the left-side rear flapping wing, the right-side front flapping wing and the right-side rear flapping wing to move in a rotating manner by a gear a, a gear f, a gear d, a gear e, a transmission shaft, a gear h, a gear g and a gear i. Compared with the prior art, the miniature insect-like double-rotation flapping wing air vehicle has the advantages that each flapping wing can move in a rotating manner; the transmission of the turbines and the worm has self-locking performance; complete symmetry of flapping of the left-side flapping wing and the right-side flapping wing is realized by the turbines and the worm; and a flapping mechanism formed by the two-end corner shafts and cylindrical supporting rods is simple in structure and flexible in flapping.

Description

technical field [0001] The invention relates to the field of bionics, in particular to a miniature insect-imitating double-rotating flapping-wing aircraft. Background technique [0002] The flapping-wing flight mode widely exists in the flight of flying creatures in nature. The flapping-wing flight includes the advantages of fixed-wing flight and rotary-wing flight. It can take off, accelerate and hover quickly, and has high maneuverability and flexibility. The flight modes of flying creatures can be roughly divided into three categories: low-frequency flapping flight, such as many large birds (hawks, vultures, wild geese, seagulls, swans, etc.), with longer and larger wingspan and low flapping frequency, It ranges from zero to tens of hertz, using low-frequency flapping and gliding in the form of flapping; intermediate-frequency flapping flight, mainly for medium-sized birds (such as swallows, sparrows, pigeons, etc.) Large, the flapping frequency is relatively high, and g...

Problems solved by technology

Patent CN200942872Y provides a dragonfly-like double-flapping-wing aircraft, but the dragonfly-like double-flapping-wing aircraft provided by the above-mentioned patent has obvious shortcomings. ) flapping wing flapping upwards, while the right (left) flapping wing flutters downwards, and its front and rear flapping wing systems are completely reverse flapping, resulting in poor flight stability of the aircraft, or even ineffective flight

In addition, the flapping wings of the flapping wing aircraft provided by these existing inventions are all one-dimensional flapping, that is, the entire flapping wing cannot rotate, so the flight movement is not flexible enough
