Abstract
The method of taking unsteady pressure measurements, on a research transonic compressor rig, was lost during the transition from the traditionally designed Vavra stage to the Sanger stage. The Sanger stage was designed using computational fluid dynamics (CFD) techniques. It required a new case wall in which the unsteady pressure sensors, due to outdated software and data acquisition system, were not initially installed. In the present study, unsteady pressure measurements were reestablished, with the installation of sensors and development of a new data acquisition and data reduction system. Data were taken at 60%, 70%, and 80% design speed. Data at 60% and 70% were compared to computational predictions and reasonable agreement was obtained.
