تمرين 1

Consider an airplane patterned after the twin-engine Beechcraft Queen Air executive transport. The airplane weight is 38,220 N, wing area is 27.3 m 2 , aspect ratio is 7.5, Oswald efficiency factor is 0.9, and zero-lift drag coefficient is C D ,0 = 0.03. Calculate the thrust required to fly at a velocity of 350 km/h at ( a ) standard sea level and ( b ) an altitude of 4.5 km.
