Programmable array type plasma jet exciter system

Abstract

The invention discloses a programmable array type plasma jet exciter system, and relates to a plasma jet system. The programmable array type plasma jet actuator system includes a direct current powersupply, a programmable high voltage pulse power supply, a drive board, a transformer, a Marx generator, and plasma jet exciters. The direct current power supply outputs direct current for the drive board, the direct current is modulated to high frequency pulse signals, and the pulse signals are converted to high frequency pulse high voltage through a transformer. The pulse high voltage is rectified to high voltage direct current through a high voltage diode and is input into the Marx generator. Capacitors of the Marx generator are connected to the cathodes and anodes of the plasma jet excitersthrough resistors. The positive electrode of the output end of the programmable high voltage pulse power supply is connected to a trigger electrode of one of the plasma jet exciters provided with thetrigger electrode, and the negative electrode of the output end of the programmable high voltage pulse power supply is connected to the cathode of the plasma jet exciter provided with the trigger electrode. The outstanding advantage of the programmable array type plasma jet actuator system is that the excitation frequency of the plasma jet array can be conveniently adjusted in real time through programmable signals. Multiple plasma jet exciters can be excited and multiple plasma jets can be generated at the same time, and so the weight, volume and energy consumption of the system can be effectively reduced when the programmable array type plasma jet actuator system is applied to the aircrafts.

Description

technical field [0001] The invention relates to a jet exciter system, in particular to an array-type plasma jet exciter system for generating multiple jets by high-voltage pulse spark discharge in an atmosphere environment under programmable control. Background technique [0002] Flow control is divided into active flow control and passive flow control. Active flow control is to directly apply the appropriate disturbance mode in the flow field of the aircraft and couple it with the intrinsic mode of the flow to realize the control of the flow. The advantage of active flow control is that it can appear at the required time and place, and obtain local or global effective flow changes through local energy input, thereby significantly improving the flight performance of the aircraft. However, passive flow control technologies, such as vortex generators and wing knives on the wings, are predetermined. When the actual flow field deviates from the design state, the best control ef...
