Rotary ornithopter with springs

Abstract

The invention provides a rotary ornithopter with springs, belonging to the technical field of air vehicles. The ornithopter comprises a body, undercarriages, energy systems, control systems, a left rotary flapping wing and a right rotary flapping wing, wherein the energy systems comprise two same motors, lithium batteries, two same reduction gear sets and speed adjusting devices; the lithium batteries are convenient to charge; each control system comprises a wireless remote control transmitter, a receiver and a steering engine; the left and right rotary flapping wings have the same structure, are respectively arranged on the left and right sides of the body symmetrically and are driven by the two motors respectively to provide pushing forces; the left rotary flapping wing comprises a left main shaft, a left rotary arm, a left vane, a left wing shaft, a left spring and a left hook; the right rotary flapping wing comprises a right main shaft, a right rotary arm, a right vane, a right wing shaft, a right spring and a right hook. The ornithopter can ascend and descend vertically and hover, has a simple structure and relatively high efficiency and is flexible. With shooting equipment, the ornithopter can be used in various tasks such as air photography, geographic survey, traffic duty, military surveillance, rescue and relief work and the like.

Description

technical field [0001] A rotary flapping-wing aircraft with springs relates to the technical field of aircraft, in particular to a flapping-wing aircraft. Background technique [0002] The lift device used in the traditional flapping wing aircraft is the traditional flapping wing mechanism, which is driven by the crankshaft and connecting rod. The flapping wing flaps up and down to generate lift. The efficiency is low. lift, and it is difficult to lift vertically and hover in the air; the traditional flapping-wing aircraft uses a single engine, which is simple in structure and light in weight, but has poor maneuverability. Contents of the invention [0003] In order to overcome the disadvantages of the above-mentioned traditional flapping-wing aircraft, the present invention provides a rotating flapping-wing aircraft with springs, the blades rotate, can lift vertically and hover, and have good maneuverability. [0004] The present invention adopts the following technical ...
