Dynamic Response of a Compressor Research Facility

Abstract

The response of the Wright Laboratory Compressor Research Facility to a small amplitude, acoustic, sinusoidal disturbance was investigated. The fluid transmission line equations for laminar, one-dimensional flow in a circular duct were solved and verified through a laboratory experiment using a scale model of the facility. The resonant frequencies of the facility were determined for a variety of flow conditions. Techniques for analytically modeling end impedance and flow straightening elements were also studied. The fundamental frequency of the facility was determined to be between 5.5 and 6.5 Hz depending on the flow conditions and geometry configurations specified.
