A scramjet propulsion system is a hypersonic air-breathing engine in which heat addition, due to combustion of fuel and air, occurs in the flow that is supersonic relative to the engine. By contrast, the airflow in a pure scramjet remains supersonic throughout the combustion process and does not require a choking mechanism. In general any scramjet engine begins with Mach number of 5. In order maintain some reduction in speed we use turbojet engines which propel from 3.2 to 4.2 Mach and from there the ramjet picks upon and starts to propel to start the scramjet. The design for a scramjet engine is carried out in this paper considering the only entry designs and numerical analysis is carried out using ANSYS FLUENT software. For the Analysis Two dimensional geometry created in the GAMBIT data taking from the public domain literature survey followed by suitable mesh was carry out. By giving the suitable boundary conditions Numerical analysis carried out using FLUENT. Analyzed results will be comparing with the experimental work for the selection of Aeromechanical features.
