Controlling the Parameters of a Shock Wave by Means of the Mass and Energy Supply

The process of controlling the parameters of a bow shock created by a body flying at supersonic velocity by supplying mass and thermal energy behind the shock is investigated. The mass and thermal energy were supplied by means of fan air jets flowing out from the body and hydrogen combustion in the neighborhood of the model, respectively. The flow parameters were measured in the neighborhood of the model and recalculated for greater distances. For these control methods some features of the variation of the shock intensity and momentum are presented. A generalization of the effect of the thrust of the nozzles forming the jets and their orientation on the shock wave parameters is obtained. The control methods considered are compared with each other.
