Plasma Actuators for Control of Crossflow Transition

PlasmadataPlots demonstrating the effect of using plasma actuators to control hypersonic transition on a cone at angle of attack.

For cones at angles of attack and many practical flight vehicles, the crossflow instability dominates transition on a significant portion of the surface. Plasma actuators have been suggested as a flow control device to suppress crossflow transition, and this technology has been investigated by our group.
