Estimate the sea-level landing ground roll distance for the airplane in Prob. 6.4. Assume that the airplane is landing with a weight of2900 lb. The maximum lift coefficient with flaps at touchdown is 1.8. After touchdown, assume zero lift. Prob. 6.4. Consider an airplane patterned after the Beechcraft Bonanza V-tailed, single engine light private airplane. The characteristics of the airplane are as follows: aspect ratio = 6.2, wing area = 181 ft2, Oswald efficiency factor = 0.91, weight = 3000 , and zero-lift drag coefficient = 0.027. The airplane is powered by a single piston engine of 345 hp maximum at sea level. Assume that the power of the engine is proportional to free-stream density. The two-blade propeller has an efficiency of0.83. a. Calculate the power required at sea level. b. Calculate the maximum velocity at sea level. c. Calculate the power required at 12,000-ft altitude. d. Calculate the maximum velocity at 12,000-ft altitude.
