1. Consider an airplane patented 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 lb, 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 the free-stream density
and does not depend on velocity. The two-blade propeller has an
efficiency of 0.83.
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. Use the
following velocities for calculating PR at the sea level: 70, 100,
150, 200, 250, 300, 350 ft/s. You may want to automate the
calculation procedure in Matlab or other program.
