An aircraft is flying at Mach number M = 1.5, where the ambient temperature is 250 K. The stagnation temperature of gases at the entry to the nozzle is 800 K. The nozzle is choked and always under expanded. Assume the molecular weight of the exhaust gases to be 29, the ratio of specific heats to be 1.4 and the universal gas constant is 8314 J/kmol-K. For which one of the nozzle exit Mach numbers given below is the thrust highest
Data for an airplane are given as follows: weight W = 30kN, thrust available at sea-level T0 = 4000 N, wing planform area S = 30 m2, maximum lift coefficient CL max = 1.4, and drag coefficient CD = 0.015 + 0.024 C2L. Assume air density at sea-level P8 = 1.22 kg/ m3. Stall speed of the airplane in m/s is
