A propeller-driven aircraft has an in-flight weight of 4,105 lb (equivalent to a mass of 1,862 kg) and is cruising at a true airspeed of 120 kts. The lift-to-drag ratio of the aircraft is 8.2. If the propeller efficiency, ηp, is 0.8, then how much brake power is required for flight? Work through this problem in both USC and SI units.
Explain the following: i. The pressure altitude of an aircraft is usually different from the temperature altitude. ii. Flow separation over an airfoil occurs at high angle of attack. iii. Lift coefficient of a wing is less than lift coefficient of the airfoil that makes up that wing. iv. High lift devices are needed during takeoff and landing.
