Abstract : The research program reviewed in this report deals with the development of a high pressure, high temperature, wind tunnel facility. The basic air supply system is referred to as the 'Mechanical Accelerator' and consists of either a single, or series, of supersonic compressor rotors; these rotors accelerate the flow at essentially constant conditions and in this manner produce a high velocity stream of gas which is capable of being used in an aerodynamic test facility. Several associated problem areas such as the boundary layer behavior in curved passages, cascade tests, surface cooling, nozzle design, and ejector performance were also investigated. The overall program led to the design development of a single stage accelerator for which the detail manufacturing and assembly drawings are available. The single stage machine resulting from this study can be used as a pilot model and will not provide the very high enthalpy, high pressure flow capability of the ultimate multistage machine.
