The aerodynamic performance of a scale-model, counterrotating unducted fan has been determined and the results are discussed herein. Experimental investigations were conducted using the scale-model propulsor simulator and uniquely shaped fan blades designed by the General Electric Company under contract to NASA. The blades, designed for a high disk loading at Mach 0.72, 35,000 ft altitude max climb condition, are aft-mounted on the simulator in a “pusher” configuration. Data are compared with analytical predictions at the design point and show good agreement.
