Consider a turbofan aircraft with the following characteristics: Sw = 560 m^2, wing span = 60 m, leading edge sweep = 27°, e = 0.87, W = 396,000 kg, Cpo = 0.016.
The airplane is equipped with 4 high bypass jet engines with 265,000 N of static thrust each at sea level. Assume the engine thrust varies directly with free-stream density.
a) Calculate the maximum velocity at sea level.
b) Calculate the maximum velocity at 11 km altitude (Ï = 0.297).
