N2 - An investigation of the effects of a pulsed plasma jet on a Mach 3 crossflow was conducted, with the goal of determining its suitability as a supersonic flow control device. The pulsed plasma jet used an electric discharge, facilitated by a two-circuit, three-electrode design, to heat and pressurize gas in a small cavity. This gas was exhausted transversely through a small orifice into a Mach 3 flow. Particle image velocimetry was used to determine the flow field created by the jet/boundary layer interaction, and it was found that the jet had a modest effect on the flow. The maximum transverse velocity induced by the jet was 61 m/s, approximately 10% of the freestream velocity. Additionally, the jet strength was found to fluctuate over the course of the pulse.
