Problems solved by technology

The Ohio State University has developed a device for parallel discharge of plasma synthetic jets. The main principle is that a DC power supply supplies power to capacitors. By triggering and controlling the on-off of 8-way MOSFET switches, the synchronous operation of plasma synthetic jets is realized. The load discharge voltage is about 4kV, and the discharg

Abstract

The invention discloses a device and a method for synchronous discharge of multiple plasma synthetic jet actuators. The method comprises the following steps: providing a power source for a pulse generator module by a first power supply, and using a pulse generator to provide a driving signal for the switch of a switching synchronization drive circuit; providing a power source for the switching synchronization drive circuit by a second power supply, and using the switching synchronization drive circuit to provide a synchronous trigger signal for switches of multiple high-voltage pulse circuits; providing a power source for the high-voltage pulse circuits comprising multiple high-voltage pulse circuit modules by a third power supply, and enabling the high-voltage pulse circuits to be matched with the plasma synthetic jet actuators to generate multipath plasma synthetic jet flows. The device and the method have the beneficial effects that the multiple plasma synthetic jet actuators synchronously run, the discharge current exceeds 100A, and a powerful synthetic jet can be generated; the device is compact in structure and is capable of running for a long time.

Description

technical field [0001] The invention relates to the technical field of plasma synthetic jet excitation, in particular to a device and method for synchronous discharge of multiple plasma synthetic jet actuators. Background technique [0002] Plasma flow control is based on the principle of aerodynamics. Plasma is generated under the action of an electric field, and flow control is realized by using the controllable disturbance of the plasma on the flow field. Plasma synthetic jet actuator has the advantages of light weight and wide operating frequency, and is the core component in plasma flow control. [0003] At present, most of the studies on plasma synthetic jets are based on a single plasma synthetic jet actuator. Patent No. 102167163 proposes a synthetic jet circulation control method to increase the lift of the wing. Although this method improves the lift of the wing, it has higher requirements on the placement of the synthetic jet actuator. Patent 104202898 designed ...
