Abstract: A logical examination on the diminishment of streamlined wave drag by hot gas infusion in hypersonic stream has been investigated. In the present investigation, dimensional axisymmetric Euler conditions are utilized as overseeing condition. Investigation has been completed for an axisymmetric limit module with and without infusion cooling for Mach number of 5.7. The scientific outcomes has been effectively approved utilizing standard exploratory information for hotgas infusion. The outcome appears around 15 % 30 % diminishment in drag coefficient for various gas infusion temperature. It turns out to be evident that an execution of the decrease of streamlined wave drag by restricting plane is incredibly influenced by jet condition.
