4. a) An ideal ramjet is flying at Mach 2 where the ambient temperature is 293 K. The fuel has a

heating value of 45,000 KJ/Kg and the temperature inside the combustion chamber is

2500 K. Find the jet exit velocity and fuel ratio. If the air mass flow through the engine is

200 Kg/s, what is the thrust produced and the thrust specific fuel consumption? For

air, ? = 1.4 and Cp= 1.0035 KJ/Kg K, which are assumed to remain constant.

b) Explain thrust augmentation technique.
