Consider an airplane patterned after the Fairchild Republic A-10, a twin-jet attack aircraft. The airplane has the following characteristics: wing area = 47 m2, aspect ratio= 6.5, Oswald efficiency factor = 0.87, weight =103,047 N, and zero-lift drag coefficient = 0.032. The airplane is equipped with two jet engines with 40,298 N of static thrust each at sea level. A) Calculate and plot the power-required curve at sea level. B) Calculate the maximum velocity at sea level. C) Calculate and plot the power-required curve at 5-km altitude. D) Calculate the maximum velocity at 5-km altitude. (Assume the engine thrust varies directly with free-stream density. TẠ, alt = 214,00) Po
