This paper presents an experimental investigation focusing on plasma flow control efficiency in hypersonic and rarefied regime. This work was carried out at the ICARE laboratory by the Fast team with the hypersonic an rarefied facility MARHY (ex SR3). Experiments concern the modification of the flow field above a sharp flat plate using a surface plasma actuator. The working condition is defined by a Mach 20.2 flow, with a static pressure of 0.068 Pa simulting pressure conditions at 100km of altitude. The plasma actuator is an aluminium alectrode placed at the leading edge of the plate and biased with a nanosecond pulsed power supply. A range of repetition rate pulse and output voltages values have been invetigated to evluate their efficiency. Flow field modifications were observed with an iCCD intensified camera and the analysis of the images showed the modification of the shock wave shape and the angle increase for all experimental conditions. |
