INVESTIGATION OF THE APPLICATION OF ELECTRICAL DISCHARGES FOR WAVE DRAG REDUCTION

Краткое описание

The problem of the main mechanism of electrical discharge influence on the wave drag of bodies at initial values of drag coefficient cx and static pressures that are of interest for aviation applications is investigated based on the experiments in classical wind tunnels with well-known and stable parameters of flows. It is shown that such a main mechanism is heat one for the types of discharges proposed for practical application. It is also shown that electrical discharges being generated in front of models can lead to unsteady supersonic flow. In turn, this stipulates essentially nonsteady flow over a body that can seem as a shock wave disappearance at insufficient time resolution of an optical method of registration.
