Problems solved by technology

However, when this kind of one-way valve injects the jet, the elastic diaphragm will be deformed indefinitely due to direct impact on the elastic diaphragm, which may cause air leakage.
This air leakage reduces the jet flow rate, thereby reducing the effectiveness of the active control of gas flow

Abstract

The invention discloses a one-way valve and a plasma synthetic jet actuator, wherein the one-way valve comprises a valve body and an elastic membrane; the valve body is provided with a first air channel, a second air channel and a valve cavity; an anti-impact structure is arranged in the valve cavity of the valve bod; the first air channel communicates with the valve cavity through the anti-impactstructure; the anti-impact structure is used for preventing air from directly impacting the elastic membrane from the second air channel when the air pressure of the second air channel is larger thanthat of the first air channel; a supporting structure is further arranged in the valve cavity of the valve body; and the supporting structure is used for ensuring that the elastic membrane opens thecommunication between the first air channel and the valve cavity when the air pressure of the first air channel is larger than that of the second air channel and closes the communication between the first air channel and the valve cavity when the air pressure of the first air channel is smaller than or equal to that of the second air channel. The plasma synthetic jet actuator is provided with theone-way valve for supplementing the air. By the adoption of the technical scheme, the air suction intensity of the plasma synthetic jet actuator in the air suction recovery stage can be increased, andmeanwhile air leakage during jet injection is avoided.

Description

technical field [0001] The invention relates to the field of aircraft active flow control, in particular to a one-way valve and a plasma synthetic jet actuator. Background technique [0002] Plasma active flow control technology is an emerging flow control technology, which uses plasma synthetic jet actuators to generate instantaneous jets with a velocity higher than 100 meters per second to achieve active flow control. At high speed, especially at supersonic flow, the plasma active flow control technology has a good active flow control effect, which has attracted extensive attention from relevant scholars at home and abroad. [0003] However, the prolongation of working time and the increase of discharge temperature in the plasma synthetic jet driven by plasma flow control often lead to insufficient suction in the recovery stage of the suction, which reduces the jet velocity and weakens the flow control ability. [0004] Chinese patent application CN104320900A discloses a ...
