Question

Air flows through a turbojet engine at the rate of 50.0 kg/s and the fuel flow rate is 1.0 kg/s. The exhaust gases leave the jet nozzle with a relative velocity of 600 m/s. Compute the velocity of the airplane, if the thrust power is 1.5 MW in the following two cases: 1. Pressure equilibrium exists ver the exit plane 2. If the pressure thrust is 8 kN

Step 1

Pressure equilibrium exists over the exit plane: In this case, the thrust generated by the engine is equal to the drag force acting on the airplane, so we can use the equation: Thrust = (mass flow rate of air + mass flow rate of fuel) x exhaust velocity Thrust = Show more…
