Abstract : The requirement for a major new Australian low speed wind tunnel is examined in this report and the form such a facility should take is proposed. The existing low speed wind tunnel has been in service for 40 years during which time it has made many valuable contributions to the needs of the military services and the australian aircraft industry, as well as to many diverse civil needs. All of the locally developed aircraft, targets and drones, guided missiles and free-fall weapons have been extensively tested in this tunnel and numerous investigation have been carried out on non-aeronautical subjects including funnel plumes, flow separations on ships' hulls, flows over airstrips and around buildings, road vehicles and wind generators. During the early sixties the tunnel performance was increased when a new power plant and fan of twice the original capacity were provided. In the seventies a digital data acquisition, recording and control system was installed to increase tunnel productivity and efficiency. However, despite these improvements, the continuing demand for tests of expanding range and diversity has produced a growing need for a larger wind tunnel with improved flow quality. A salient factor has been the increased emphasis in recent years on support for Australian military air operations.
