An aircraft with a reference wing area of 174 ft and wingspan of 37.31 ft is cruising at 10,000 ft. on a standard day. The aircraft is cruising at 172 ft/s and is known to have a C = 0.4651 and CD = 0.02813. a. What is the total lift and drag of the vehicle in this condition? (2 points) b. If the coefficient of zero-lift drag is 0.01800 for this vehicle, what is the coefficient of induced drag in this condition? (1 point) C. What is the value of Oswald's efficiency factor for this vehicle? (1 point) A subscale model is begin tested in a wind tunnel at Georgia Tech. The wind tunnel is currently operating at 75 ft/s and draws air in from the ambient atmosphere (approximately 1000 ft. altitude). The model features a wing area of 5 ft. a. A total of 6 lbf. of lift is generated by the test article. What is the value of C? (1 point) b. A total of 0.78 lbf of drag is generated by the test article. What is the value of CD? (1 point) C. File Preview Assuming a lift curve slope of 2 1/rad, what is the angle of attack of the test article? (1 point)
