What is Plasma Actuation for the Control of a Supersonic Projectile about?

The generation of a plasma discharge on a projectile surface seems to be a way of producing a pressure imbalance to divert a projectile from its initial trajectory. Thus, some experiments dealing with the steering of a supersonic projectile by using a plasma actuator are presented. The plasma discharge is produced by an embedded low-voltage generator capable of delivering an electric discharge between the electrodes flush with the projectile surface. A first series of experiments carried out under wind-tunnel conditions at a Mach number of 3 allows the detailed study of the perturbation evolution along the projectile surface, the disturbance being generated by the plasma discharge. A second series of experiments in the wind tunnel at the same Mach number demonstrates that a plasma discharge generates the angular deviation of a fin-stabilized projectile: 243 J of stored energy delivered in 2.5 ms at the conecylinder junction of the projectile induces an angle of attack of 2 deg after the plasma-discharge generation. Other experiments conducted in a shock-tube facility under low-altitude conditions prove that it is possible to activate a plasma discharge on a projectile flying at a M
