Problem 1 For a certain wing the lift force is 3000 lb when it is moving at 200mph through standard see level atmosphere conditions. The centre of pressure is 2.4 ft aft of the leading edge. The span is 36 ft, the average chord is 6 ft. Find the pitching moment coefficient about: a) the leading edge; b) the centre of pressure; c) the trailing edge. Problem 2 If the aircraft of Problem 1 travels, at the same angle of...

HW#4 (Due 3/14/2019) Problem 1: (10pts) Consider a wing is mounted in a subsonic wind tunnel, where the airflow velocity is 50 m/s. If the velocity at a point on the wing is 60 m/s, what is the pressure coefficient at this point? Problem 2: (1Opts) In Problem 1, if the test section air temperature is 280 K, and if the flow velocity is increased point? to 200 m/s, what is the pressure coefficient at the same
