The Weybridge wind tunnel is an open section closed return wind tunnel, primarily used for static and dynamic testing of small models, component testing, calibration and demonstrations. Read more Read less

The tunnel is equipped with the facility to mount models from overhead or under working section struts and can also be configured with an automated pitching and yawing crescent. Test techniques typical include force and moment measurements, time averaged and unsteady pressure measurement, traversing of rakes and probes for wake studies, flow visualisation and optical measurements.
