(a) (b) (c) An aircraft is flying at an altitude of 10 km at a Mach number equal of 0.8. Its engine thrust is equal to 50 kN, air mass flow rate is equal to 45 kg/s and fuel mass flow rate is 2.65 kg/s. The fuel lower caloric value (LCV) is equal to 42.8 MJ/kg. Find the exhaust velocity from the engine if the speed of sound at 10 km is equal to 300 m/s. Find the propulsion, thermal and overall efficiencies. [13 Marks] [12 Marks] What is the physical sense of propulsive and thermal efficiencies? What is the thermal efficiency of modern turbines? ro Markel (a) (b) (c) An aircraft is flying at an altitude of 10 km at a Mach number equal of 0.8.
