The results of the experimental study of the influence of heat transfer on the increase of the bottom pressure (reduction of bottom resistance) at supersonic and hypersonic speeds are presented. Different ways of heat transfer due to combustion of gasless pyrotechnic compositions and fuel elements are considered. It is shown, that fuel elements with the tungsten coating mounted on the model with a fodder reflector, increase the bottom pressure by up to 60%. A method of cooling the head parts of aircraft and of heating their bottom part using the effect of the heat tube is proposed.
