Influence of density inhomogeneity of supersonic flow on heat flux and temperature on a plate has been studied experimentally. The inhomogeneity of the supersonic free stream was obtained by injection of a thin helium jet into the main air stream. Such approach allows to model impact of an infinitely long heated stream of gas, with lower density than gas of the main flow, on body aerodynamics. Reorganization of the gas flow around the body leads to the considerable change of power loading and a heat flux. Results of a research of a heat transfer coefficient are discussed.
