The overall setup of the wind tunnel.  This wind tunnel has a 1 square ft. test section a maximum flow velocity of 50 m/s.

A close-up of the test section with the NACA 0015 symmetric airfoil with 10 cm chord with surface pressure taps on one surface.  The airfoil spans the tunnel test section and a multi-tube water manometer board is used to monitor the surface pressure taps and provide a visual display of the dynamic changes associated with varying attack angles.
