Consider an airplane patterned after the Fairchild Republic A-10, a twin-jet attack aircraft. The airplane has the following characteristics: wing area = 47 m, 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 of static thrust each at sea level. The thrust-specific fuel consumption is 1.0 N of fuel per Newton of thrust per hour. The fuel capacity is 2300 gal, and the maximum gross weight is 136,960 N. Calculate the range and endurance at a standard altitude of 8 km, where p = 0.526 kg/m. The range of the twin-jet aircraft at an altitude of 8 km is | The endurance of the twin-jet aircraft at an altitude of 8 km is km. hr.
