Comparative Tests of Thick and Thin Turning Vanes in the Royal Aircraft Establishment 4x 3-ft Wind Tunnel

摘要

The tests were made by replacing the existing centre six thick vanes at the first corner of the 4 x 3-ft wind tunnel by vanes of sheet metal.nThe thin vanes reduced the corner loss, estimated from a wake traverse behind one vane, without any deterioration in outflow, and are therefore recommended for use in future wind tunnels.
