The report presents the results of a continued compressor technology program directed toward development of a small, advanced, two-stage centrifugal compressor designed to attain high pressure ratios with fixed geometry. Extensive compressor performance data were obtained for two test configurations. The second test configuration, incorporating a minor rematch to the first-stage compressor components, and operating at a design speed of 82,000 rpm, gave a peak adiabatic efficiency of 78 with a pressure ratio of 13.2 and a corrected airflow of 1.94 pps. The compressor exhibited extremely wide flow ranges between surge and choke, with peak efficiencies away from the surge line.
