Hypersonic Shock

The experimental method and devices allowing to realize interference principle of active control of pulsations intensity in a hypersonic shock layer on flat plate in flow of nitrogen at Mach-number M∞ = 21 are described. The results of measurements of disturbances characteristics and results of realization of interference process in the wind tunnel experiment are compared with the data of direct numerical simulation on the basis of full unsteady Navie-Stocks equations.
