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 application discloses a one-way valve and a plasma synthetic jet actuator. Among them, the one-way valve includes a valve body and an elastic diaphragm; the valve body is provided with a first air passage, a second air passage and a valve chamber; the valve body is provided with an anti-shock structure in the valve chamber, and the second air passage passes through the anti-shock structure Connected with the valve chamber, the anti-shock structure prevents the gas from directly impacting the elastic diaphragm from the second airway when the pressure in the second airway is greater than the pressure in the first airway; the valve body is also provided with a support structure in the valve cavity, and the support structure is used for Ensure that the elastic diaphragm opens the communication between the first airway and the valve cavity when the air pressure in the first airway is greater than the air pressure in the second airway, and closes the first airway when the air pressure in the first airway is less than or equal to the air pressure in the second airway. The communication between the channel and the valve cavity. The plasma synthetic jet actuator is attached with a one-way valve as described above for gas supply. By adopting the above-mentioned technical solution, the suction volume of the plasma synthetic jet actuator in the suction recovery stage can be increased, and at the same time, air leakage will not occur when the jet is sprayed.

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 exciter. Background technique [0002] Plasma active flow control technology is an emerging flow control technology that utilizes plasma synthetic jet exciters to generate instantaneous jets with a velocity higher than 100 meters per second to achieve active flow control. At high speed, especially in supersonic flow, the plasma active flow control technology has better active flow control effect, which has attracted extensive attention of related scholars at home and abroad. [0003] However, the plasma synthesis jet driving plasma flow control often causes insufficient suction in the suction recovery stage due to the prolongation of working time and the increase of discharge temperature, which reduces the jet velocity and weakens the flow control ability. [0004] Chinese patent application CN104320900A discloses a gas-suppl...
