Consider an airplane patterned after the fairchild republic a-10, a twin-jet attack aircraft. the airplane has the following characteristics: wing area=47m2, aspect ratio=6.5, oswald efficiency factor=0.87, weight=103,047n, 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.)
