Abstract: Generally a Scramjet Engine starts at a hypersonic freestream Mach no. 5.00. In order to propel to those speeds, we use turbojet engines which propel to around 3.00-4.00 Mach and from there the ramjet picks upon and starts to propel to start the scramjet engine. If we reduce the scramjet engine starting Mach number to say 3.50 or 4.00, we can eliminate one propulsion engine, i.e., ramjet engine and thus reducing weight and complexity. The design for such a scramjet engine is carried out in this project considering only the inlet designs and the flow analysis is carried out in CFD. A two dimensional analysis is carried out in this project. GAMBIT is used to create a model. FLUENT is used to cover the flow analysis.
