Abstract

The invention discloses a high-flow and high-frequency pulse air blowing device. The device comprises a front-end plenum chamber; one end of the front-end plenum chamber is an air inlet end, and the opposite other end is an adapter end; the device further comprises a rotating shaft which is provided with an inner cavity with one end communicating with the adapter end, and multiple sets of air guide holes communicating with the inner cavity are formed in the side wall of the rotating shaft; the device further comprises a shell which is arranged outside the rotating shaft; a group of air blowingholes are formed in the shell, and the positions of the air blowing holes match those of the air guide holes; the device further comprises a motor which is connected with the rotating shaft and drives the rotating shaft to rotate. The high-flow and high-frequency pulse air blowing device can be used for high-flow and high-frequency pulse air blowing, and can be suitable for a large-size model pulse air blowing flow control test.

Description

technical field [0001] The invention relates to a large-flow, high-frequency pulse blowing device, which belongs to the technical field of flow control. Background technique [0002] As the frontier and branch of fluid mechanics research, flow control technology has been widely concerned by researchers. Through the flow control of the aircraft, control effects such as lift increase, drag reduction, noise reduction, and deicing can be achieved, laying the foundation for the development of the next generation of aircraft. According to the way of actively injecting energy into the flow field, the flow field control technology can be divided into passive control and active control. Commonly used passive control technologies include: vortex generators, Gurney flaps, etc.; active control technologies include: air blowing, air suction, synthetic jets, etc. [0003] Pulse blowing flow control technology is a typical active flow control technology. The quasi-sequential structure o...
