An impulse-type supersonic compressor rotor with stators was tested in Freon-12 over a range of equivalent tip speeds and weight flows. A stage pressure ratio of 1.83 and an efficiency of 84.7 percent were obtained at 69.1 percent of the design speed of 1604 feet per second in air. Efficiency decreased rapidly with increasing tip speed to a value of 66.8 percent at a pressure ratio of 2.6 at 96.6 percent design speed.
