Consider an airfoil in a high-­?speed wind tunnel. At the minimum-­?pressure point on the wing, the velocity is 900 ft/s. If the test section flow velocity is 750 ft/s at standard sea-­? level conditions:

a) Calculate the pressure coefficient at this point on the wing.

b) Calculate the critical pressure coefficient corresponding to this flight condition.

c) Comparing your answers from parts (a) and (b), what conclusion can you make as to the nature of the flow over the wing? What is the significance of this conclusion with respect to the drag on the airfoil?

A new two-dimensional airfoil constant chord model is being tested in a wind tunnel. The model chord is 3ft. The atmosphere is standard. The velocity of the airflow is 250 ft/s. The forces are resolved as 150lb of perpendicular to the relative wind and 10lb parallel to the relative wind.
