A Cessna Citation Has A Gross Weight Of 68 Kn And A Wing Area Of 28 M In A Hold Pattern Prior To Landing The Speed An 2 (24.62 KiB) Viewed 42 times
A Cessna Citation has a gross weight of 68 kN and a wing area of 28 m². In a hold pattern prior to landing, the speed and altitude are 250 knots (128.6 m/s) at 10,000 ft (3,000 m). If the wings are constructed using a NACA 23012 airfoil shape what is the angle of attack required to maintain this altitude neglecting finite wing effects? If the fuselage adds an additional 0.008 to the drag coefficient of the wings to make the overall vehicle drag coefficient, what is the thrust required of the engines to maintain the hold condition? What is the net power of the engines required at the hold condition assuming? (The NACA 23012 performance curves are shown on the next page.)
