HOMEWORK #6

Due Monday April 1

!!Caution: Still under development!!

1. The Cessna Citation has the following characteristics approximately:
   weight = 19815 lb
   wing span = 53.3 ft
   wing reference area = 318 sq. ft.
   Oswald efficiency = .85
   If the aircraft is flying at 15,000 ft in the standard atmosphere, at an equivalent airspeed of 250 ft/s an requires a thrust of 2220 lb to maintain straight and level flight, determine:
   1. lift coefficient
   2. total drag coefficient
   3. induced drag coefficient
   4. profile drag coefficient
2. The aircraft of the previous part comes in to land at sea level at an equivalent airspeed of 120 ft/s. Assuming the profile drag coefficidoes not change
