Unformatted text preview: Characteristics: Wing span = 75.0 ft. Wing area = 950 ft 2 . Weight, without fuel* = 43,500 lb. Parasite drag coefficient = 0.015 Oswald efficiency factor = 0.7 Specific fuel consumption = 0.69 lb/lb-hr . * ie., weight at the end of loiter 2 . A propeller driven airplane weighing 5000 lb. is flying for maximum endurance at sea level with a velocity of 200 mi. hr-1 . The wing area and aspect ratio are 200 ft 2 and 8.5, respectively. The Oswald efficiency factor is 0.93. Calculate the total drag on the airplane. (sea level density is 0.002377 slug.ft-3 , and 1 mi. = 5280 ft.)...
