Ggg Consider an airplane modeled after the Fairchild Republic A-10, a twin-jet attack aircraft. Theairplane has the following characteristics: wing area = 47 m2; aspect ratio = 6.5; Oswaldefficiency factor = 0.87; weight = 103,047 N; and zero-lift drag coefficient = 0.032. The airplaneis equipped with two jet engines, each with 40,298 N of static thrust at sea level. Assume thevelocity of the airplane is 310 m/s.Calculate the power required at sea level. (Round the final answer to the nearest wholenumber. Answer this part of the question before moving on to the next part.)
