A small rotary flapping wing unmanned aerial vehicle

Abstract

The invention provides a small rotary unmanned ornithopter, belonging to the technical field of air vehicles. The ornithopter comprises a body, undercarriages, an energy system, control systems, a left rotary flapping wing and a right rotary flapping wing, wherein the energy system comprises a motor, a lithium battery, a reduction gear set and a speed adjusting device; the lithium battery is convenient to charge; each control system comprises a wireless remote control transmitter, a receiver or an automatic navigation control device 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 power 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 guide rod and a left guider; the right rotary flapping wing comprises a right main shaft, a right rotary arm, a right vane, a right wing shaft, a right guide rod and a right guider. The ornithopter can ascend and descend vertically and hover and has a simple structure and relatively high efficiency. 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 small rotary flapping-wing unmanned aerial vehicle belongs to the field of aircraft technology, in particular to a flapping-wing unmanned aerial vehicle. 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. Thrust, and it is difficult to lift vertically and hover in the air. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned traditional aircraft, the present invention provides a small-sized rotary flapping wing unmanned aerial vehicle, the flapping wing performs a rotary motion, and can vertically lift and hover. [0004] The present invention adopts the following technical scheme: a small-sized rotary flapping-wing unmanned aerial vehicle includes a fuselage, a landing gear, an energy system...
