A ramjet drives a missile at V0=966m/s at an altitude of 33.5km (air density 0.01kg/m3 and T0=232K). If the missile inlet captures a stream tube of air A0=1,1m2 in area, the fuel-to-air ratio is 0,049, and the fuel heating value is 50MJ/kg. if the ramjet engine produces net thrust Fn= 8,9 kN ,  What is the useful power that the engine introduces to the missile?

Question

A ramjet drives a missile at V0=966m/s at an altitude of 33.5km (air density 0.01kg/m3 and T0=232K). If the missile inlet captures a stream tube of air A0=1,1m2 in area, the fuel-to-air ratio is 0,049, and the fuel heating value is 50MJ/kg.

if the ramjet engine produces net thrust Fn= 8,9 kN , 

What is the useful power that the engine introduces to the missile?
