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 temperature-pneumatic 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. Verification of the calibration in steady flow and application of the probe to obtain radial surveys in a small axial compressor are also described. The procedures developed and reported here allow the probe to be used with automatic reduction of data by mini-computer without the need for iteration. (Author)
