TASK II STAGE DATA AND PERFORMANCE REPORT FOR UNDISTORTED INLET FLOW TESTING VOLUMEⅠEVALUATION OF RANGE AND DISTORTION TOLERANCE FOR HIGH MACH NUMBER TRANSONIC FAN STAGES

摘要

A compressor stage consisting of a 1500 ft/sec tip speed rotor, a variabíé-camber inlet guide vane, and an adjustable stator, was tested with undistorted inlet flow at several inlet guide van ánd stator settings. The objectives of the tests were to obtain blade element data arid to evaluate the effectiveness of the variable geometry blading at several key points in an operating envelope typical, of;a Mach 3 turbofan engine. The overall performance and the blade, element data obtained at the three combinations of IGV-stator settings at 50, 70, 80, 90, 100, and 110 percent design speed are presented in two volumes.nThis volume, the first of the two, presents details of the test equipment, test procedure, data reduction methods, overall performance data and plots of blade element data. Volume II contains tabulations of all the overall performance and blade element data.
