A rocket engine has the following data: Effective jet velocity = 1400 m/s Flight to jet speed ratio = 0.82 Oxidizer flow rate = 3.5 kg/s Fuel flow rate = 1.2 kg/s Heat of reaction per kg of the exhaust gas = 2600 KJ/kg. Calculate the thrust, specific impulse, propulsive efficiency, thermal efficiency and overall efficiency.
