A multidischarge actuator system for power electrohydrodynamic action on the boundary layer of aerohydrodynamic surfaces

We present the results of a study of a new multidischarge actuator system designed for active gas flow control on the basis of a three-electrode circuit with a shielding electrode, in which the role of an accelerating electrode is played by the solid equipotential sheath surface of the wing.

Summary:We present the results of a study of a new multidischarge actuator system designed for active gas flow control on the basis of a three-electrode circuit with a shielding electrode, in which the role of an accelerating electrode is played by the solid equipotential sheath surface of the wing. The main parameters of the multidischarge actuator system and classical scheme of electrodes are compared—namely, the induced air flow velocity, average integral volume force, average consumed power, and energy efficiency coefficient calculated per unit length of the external electrode.
