Problems solved by technology

However, in real life, it is often difficult to capture the trajectories of insects with high-frequency flapping movements, and it is even more difficult to analyze the changes in the flow field generated by the wake during flight.

Abstract

Discloses is a flight flow field measurement device of a bionic insect. The device includes a groove body and a support body; the groove body is internally provided with the bionic insect, bionic wings are arranged on the bionic insect, and a high-speed camera is arranged above the groove body. The device mainly aims at solving the technical problem that during research on flying insects, flow fields generated by wings during flight of the insects cannot be well obtained.

Description

technical field [0001] The invention belongs to the field of insect research, and in particular relates to a bionic insect flight flow field measuring device. Background technique [0002] Insects generate propulsion by flapping their wings when they fly, and the reaction force of the air fluid. The researchers found that its propulsion efficiency is much higher than that of current man-made aircraft. However, in real life, it is often difficult to capture the flight trajectory of insects with high-frequency flapping movements, and it is even more difficult to analyze the changes in the flow field generated by the wake during flight. [0003] The Chinese patent with the notification number CN2581325Y discloses a flapping wing device, which uses the resistance generated when the spring is twisted and the elastic force generated when it is restored to make the motor shaft rotate one circle, and the eccentric movement rate of the sleeve varies from slow to fast, resulting in b...
