EXPERIMENTAL DETERMINATION OF THE FREQUENCY RESPONSE OF 0.020-INCH INSIDE DIAMETER TUBES AND VALIDATION OF A THEORETICAL MODEL

摘要

The Compressor Research Facility (CRF) of the Aero Propulsion Laboratory's Turbine Engine Division at Wright-Patterson AFB, Ohio will perform a rig test of an F100 High-Pressure Compressor in 1987. One of the highlights of this test will be the acquisition of poststall performance data. Close-coupled and high-response instrumentation will be used to make the necessary dynamic pressure measurements. This report describes the experimental effort to determine the frequency response of the close-coupled pressure instrumentation on the CRF/F100 compressor rig. Experiments were conducted on various lengths of the 0.020-inch-inside-diameter steel tubing used to connect the test article pressure probes to Scanivalve ZOC14 pressure transducers. From these experiments, transfer functions were obtained describing the amplitude response and phase shift characteristics for several tube lengths as a function of the input pressure oscillation frequency.
