Acquisition and Reduction of Rotor-Tip Static Pressure Transducer Data From a LowAspect Ratio Transonic Fan

摘要

This report details the acquisition and reduction of Over-The-Rotor (OTR) staticpressure data. These data were acquired during the Augmented Damping of Low Aspect Ratio Fans (ADLARF) test conducted at the Compressor Research Facility (CRF). The CRF is located at Wright Laboratory on Wright-Patterson A.F.B. in Ohio. The CRF is one of two high-speed compressor test facilities at Wright Laboratory. The report is primarily concerned with the acquisition and reduction of the OTR data, and is intended to demonstrate the ability to reduce, display, and analyze static pressure data acquired from the tip region of fans and compressors. The ability to show basic shock structure in the tip region of a transonic fan is clearly demonstrated. Problems associated with the acquisition and reduction process are also addressed. Although these data were originally intended only to demonstrate proof of concept, they have also provided valuable insight concerning the tip flow region of the ADLARF fan. (AN).
