Problems solved by technology
[0002] The traditional flapping wing aircraft relies on the crankshaft linkage mechanism to drive the flapping wings, and the flapping wings flutter up and down to generate lift. The efficiency is low, and the direction of the lift is not adjusted in any direction, and the fatigue strength of the flapping wing material is high.

The invention relates to a rotary flapping wing thrust generation device provided with a spring, belonging to the technical field of aircrafts. The rotary flapping wing thrust generation device consists of a main shaft, a rotary arm, a flapping wing, a wing shaft, the spring and a hook, wherein a crank is formed by the main shaft, the rotary arm and the wing shaft; one end of the spring is fixedly connected with the flapping wing, and the other end of the spring is connected with a machine body by the hook. The flapping wing is driven to rotate along the circumference by an engine, and the air is flapped to generate thrust, so that the rotary flapping wing thrust generation device is high in efficiency and lower in requirement on the fatigue strength of material; the rotary flapping wing thrust generation device is simple in structure and more convenient in thrust direction adjustment, and can be used as a thrust device of the aircraft.
Description
technical field [0001] A rotary flapping wing thrust generating device with a spring belongs to the technical field of aircraft, and in particular relates to a thrust generating device for an aircraft. Background technique [0002] The traditional flapping wing aircraft relies on the crankshaft linkage to drive the flapping wings, and the flapping wings flutter up and down to generate lift. The efficiency is low, and the direction of the lift is not adjusted in any direction, and the fatigue strength of the flapping wing material is high. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned defects of traditional flapping-wing aircraft, and to invent a highly efficient rotatable flapping-wing thrust generating device similar to rolling wings. [0004] A rotating flapping-wing thrust generating device with springs, which is composed of a main shaft, a rotating arm, a flapping wing, a wing shaft, a spring and a hook; one ...
