Effect of power supply modes of multi-discharge actuator systems on their electric discharge and gas-dynamic characteristics.

In recent years, much attention has been paid to the development of plasma aerodynamics. Among the main tasks to be solved in this area are an increase in thrust force, induced velocity and efficiency of operation of multi-discharge actuator systems used to control air flows. This work presents the results of experimental studies of the dependencies of the characteristics (thrust force, speed of the created air flow, power consumption) of such systems on the parameters of the power mode (voltage, frequency, pulse front duration) with unipolar high-voltage pulses with a bias voltage and comparison of these characteristics when working with other power modes. • High-voltage power supply system provides DC bias voltage to MAS electrodes in combination with repeated unipolar pulses. • High-voltage power supply system with rectangular voltage pulses for multi-discharge actuator system is created. • Electric discharge and gas dynamic characteristics of MAS under various power supply modes were investigated. • At optimal actuator system power supply modes comparable values of thrust force and airflow rates are achieved.
