A Ram Jet Engine flies with 2.5 Mach number, where the ambient pressure and temperature are 60 kPa and 250 K, respectively. The Engine consists of three components: I- Inlet Spike Intake: It is of a double type 10O for each. The air decelerated, externally, by two oblique shocks followed by normal one (1 to 4). Then deceleration occurs internally though an isentropic diffuser until the Mach number reaches 0.3 at the intake exit (point 5). II- The Combustor:: Where the fuel in injected and burned
