Development of Methods for Diagnostics of Discharges in Supersonic Flows

This report results from a contract tasking M.V. Lomonosov Moscow State University (MSU) as follows: The contractor will develop methods of measurements of plasma parameters of the electric discharges in supersonic air flows of propane-air mixtures. The experimental investigation of spatial and temporary evolution of parameters of plasma discharges of various types of the discharges (longitudinal direct current, transversal pulsed-periodic, plasma dynamic discharges) and combustion plasma in supersonic flows will be carried out at Mach number M=2 in a pressure range 10-400 Torr. The following plasma parameters will be measured: charged particle densities gas and vibrational temperatures. floating and plasma potential. transversal and longitudinal electric field in plasma. He will also develop the laboratory prototype of a compact automated diagnostic probe complex for measurement of local parameters plasma in supersonic flows in a real time mode. This Project consists of two tasks. Task 1 is devoted to development of the complex of diagnostic methods (probe and spectroscopic) that will enable to indicate ignition and combustion of air-fuel mixture in supersonic flow and to measure parameters of discharge and combustion plasma. Task 2 will be devoted to creation of the laboratory prototype of a compact automated diagnostic complex for measurement of local parameters of plasma supersonic flows in a real time mode.
