Abstract

The effect of an optical pulsed discharge created by CO2-laser with an average power of up to 2.2 kW on the aerodynamic drag of a model in a supersonic air flow is experimentally investigated. Experiments were carried out in a supersonic wind tunnel MAU-M (diameter of the nozzle outlet dc = 50 mm) on the modes M = 1.36, Re1 = 1.4- 3.8∗107 1/m. To ensure a stable optical breakdown, a jet of argon gas was introduced into the focusing region of the laser beam. As a result, a decrease in the aerodynamic force acting on the model was obtained. This decrease was 15% when a subsonic flow of argon was introduced into the main flow and another 15% when optical pulsed discharge was organized.
