Abstract:

The ARL-Salisbury S1 wind tunnel is a closed circuit, continuous, variable pressure wind tunnel, with a Mach number range of 0.35 to 1.0 and 1.4 to 2.8. The nominal dimensions of the tunnels working section are 380 mm x 380 mm. Although the tunnel has been in operation for many years, no attempt has been made to experimentally investigate and establish the operational pressure limits. Thus, it is not uncommon for new experimenters to request running conditions which tunnel cannot achieve. This is further complicated by new temperature and current limits being adopted in 1985 after a main monitor failure. Therefore, a series of wind tunnel test runs were carried out in order to provide a reliable guide, outlining the running conditions which the S1 wind tunnel can safely achieve. This report outlines the absolute maximum pressure and the recommended maximum operating pressures for the S1 wind tunnel. The pressure limits calculated in this report were obtained from actual wind tunnel data records.
