Initiated Surface Microwave Discharge as an Efficient Active Boundary-Layer Control Method

Abstract

The first-step result of experimental works on verification of advanced method of boundary-layer control based on localized plasma generation is presented. Boundary-layer control is executed by means of vortex structure creation near streamlined body surface. Experiment has been performed in specially designed wind tunnel. The microwave radiation remotely feeds a resonant distributed system, initiating and sustaining the point discharges, generating the vortex structure in the stream. Measurement data together with results of modeling confirms the feasibility of initial idea.
