Problem 4: (20 pts) A small business jet has the following characteristics: Take-off weight: W = 24,700 N Wing reference area S = 22.3 m Drag polar: Cp = 0.017 + 0.117C2 (drag polar is constant) Maximum lift coefficient is 2.0 (with flaps) Ground-roll friction coefficient = 0.03 (dry concrete) for take-off Ratio of wing height above runway/wing span is h/b = 0.08 ACDgear = 0.02 and ACDflaps = 0.015 (extra drag for take-off) Total average thrust Tavg= 15,000 N (at sea level, from brake release to liftoff) Determine the total takeoff distance to clear a 50-ft obstacle.
