Surface Microwave and Surface Transversal Pulsed-Periodic Discharges in Supersonic Flow
Abstract
This report results from a contract tasking Moscow State University (MSU) as follows: The contractor will develop methods of creation of plasmas of different types of gas discharges near the surface of Aerodynamic models and in the boundary layers. Also, the contractor will develop modes of internal and external fuel ignition of propane-air and hydrogen-air mixtures. He will develop methods of analysis of plasma properties in plasma regions near the surface. The following experimental work will be done in supersonic air flow (M<2) at pressures between 1 and 200 Torr: a) measurement of variation of the displacement thickness of boundary layer at creation of surface microwave and surface transversal pulse-periodical discharges on a flat plate; b) measurement of plasma parameters of a flame formed in a supersonic flow at internal and external fuel ignition with the help of the microwave discharges. A theoretical analysis of the obtained results will also be delivered. Recommendations for using of microwave surface and volumetric discharges for supersonic aerodynamics will be worked out. This Project consists of two tasks, 1) Task 1 is devoted to investigation of large-area plasma of surface discharge with the purpose of elucidating the interrelationship of electrodynamical, gasdynamical and kinetical properties of plasma of surface discharge. Such information is of paramount importance for practical application of gas surface discharge in supersonic aerodynamics; 2) Task 2 will be devoted to investigation of application of the surface and volumetric freely localized microwave discharges both for internal and external ignition in supersonic flows of combustion such as air-propane, and air-hydrogen mixtures.
