Extract

The RAE Boundary Layer Tunnel is an open return facility driven by a 100 hp ventilating fan. It is provided with interchangeable working sections of cross-section either 1·2m × 0·3 m or 0·6 m × 0·6 m. There is no diffuser downstream of the working section which exhausts directly into the test room. The tunnel was arranged in this way to avoid restrictions on the design of the working sections and also in order to enable control of the pressure in the working section by means of a screen over the exit. This control made it possible to bleed flow from the working section, to avoid unwanted separations, for example, or to provide some special flow characteristic.
