A turbojet engine consists of a diffuser, compressor, combustor, turbine and a converging nozzle. The engine is operating on an aircraft flying at 260 m/s at an altitude where the air is at 61 kPa and -11 °C. The inlet diameter of this engine is 1.6 m; the thrust produced by the engine under ideal cruising conditions is 93,625 N; and the temperature at the turbine inlet is 750 °C. Assume constant specific heat values at room temperature, choked flow...

2. An aircraft with a single turbojet engine (with an inlet area of 1 m2) is flying at cruising condition with a flight Mach number of 0.7. The ambient temperature and pressure are 250 K and 100 kPa, respectively. The engine compressor pressure ratio is 12, and the turbine inlet temperature is 1200 K. Assume all mechanical components are operating at isentropic condition and the specific heat can be considered a constant (throughout the entire engine) of 1 kJ/(kg K)....

A J57 turbojet engine is tested at sea-level, static, standard-day conditions (Po = 14.696 psia, To =518.7°R, and Vo = 0). At one test point, the thrust is 10,200 lbf while the airflow is 164 Ibm/s and the fuel flow is 8520 lbm/h. Using these data, estimate the exit velocity Ve for the case of exit pressure equal to ambient pressure (Po - Pe).
