Acquisition and Reduction of Blade-Mounted Pressure Transducer Data from a Low Aspect Ratio Fan.

Abstract

This report details the acquisition and reduction of blade-mounted, high-response, pressure transducer data. These data were acquired during the Augmented Damping of Low Aspect Ratio Fans (ADLARF) test conducted at the Compressor Research Facility (CRF) located at Wright-Patterson A.F.B. , Ohio. This report, which is exclusively concerned with the acquisition and digitizing of the blade-mounted data, is intended to compliment other related reports by documenting the data acquisition and reduction procedures. The primary goal of this work is to detail the methodology by which unsteady blade forces and momentum can he determined using blade-mounted pressure transducer data. The secondary goal is to use these data to show how inlet distortion and resulting unsteady forces affect the blade resonance of high-speed fans. By achieving the primary goal in this report, it is hoped that the secondary goal can be better achieved using data from future tests.
