Calibration and application of a combination temperature-pneumatic probe for velocity and rotor loss distribution measurements in a compressor

Abstract

A description is given of the current design of a temperaturepneumatic probe used for radial flow field surveys in an axial compressor. The procedure used to calibrate the probe for variations in Mach number, pitch and yaw angles in a free jet is described and the procedure for representing the characteristics of the probe analytically as three polynomial surfaces, is given.
