Question 9 - Ramjet Operation (15 Points): You are asked to calculate the operational parameters of an ideal ramjet engine. flame holder combustion zone P-P Me nozzle Min V M inlet diffuser Normal shock wave Ramjet e-Nozzle exit throat-M-1 2-Diffuser exit 3-Burner exit Flight Mach number is 2.0. Burner exit temperature is 1700 K. Flight altitude is 10 km. Make the following assumptions: Assume that the Mach number in the combustor is zero (stations 2 and 3) Flow in the diffuser and nozzle are isentropic (not through the shock wave though!) Assume ideal gas and calorically perfect gas. Ignore pressure losses in the combustor (P2=P3) . Perfect nozzle (exit pressure is matched to the atmospheric pressure) a) Calculate the nozzle entrance (burner exit) pressure. b) Calculate the nozzle exit velocity. c) Calculate the heat addition (per unit mass flow rate) to the ramjet engine d) Calculate the overall efficiency of the ramjet engine e) Calculate the propulsive efficiency. f) If the nozzle throat diameter is 0.2 m, calculate the thrust of the ramjet system.
