Web2.2 An ideal ramjet engine is being designed for a Mach 3.2 aircraft at an altitude of 10000 m. The fuel has a heating value of 43263.6 kJ/kg, and the burner exit total temperature is 1889 K, A thrust of 42258 N is needed. What is the required airflow? What is the resulting nozzle exit diameter? What is the resulting TSFC and dimensionless thrust? WebJul 27, 2024 · F = (m dot * V)e – (m dot * V)0. The first term on the right hand side of this equation is usually called the gross thrust of the engine, while the second term is called the ram drag. It is a drag term because it is subtracted from the gross thrust. Since the exit mass flow rate is nearly equal to the free stream mass flow rate, and the free ...
