Abstract:

The data acquisition system used by the Subsonic Wind Tunnel at Aeronautical Research Laboratory, Melbourne, was designed in 1972. Tunnel productivity was further improved during 1982 with the installation of a dedicated computer PDP1144 which eliminated the time sharing access with the sites central computer. The dedicated computer also provides real-time processing of data and supports graphical displays for interactive operation with wind tunnel tests. In recent years this dedication minicomputer has become unreliable and the high cost of maintenance has led to its replacement with a micro VAX which is intended to be connected to similiar data gathering equipment to that used in the Subsonic Wind Tunnel. A data bus was developed to provide bi-directional communication between the dedicated master mini computer and the numerous microprocessor slave modules which form the new system.
