Real time measurements in a transonic compressor
Abstract
Current work at the Naval Postgraduate School for the experimental determination of the behavior of flow in a transonic compressor stage is reviewed. The goals of the research program are presented, and results of time-averaged flow measurements made in the initial test program - considered to be relevant to the program of real-time probe measurements - are given. Development of techniques to be applied in the acquisition of real-time test data is discussed. In the compressor tests now underway, 'continuous' sampling is used with an acquisition rate of 100,000 sample/sec. The 'synchronized' sampling described is expected to provide a promising method of analyzing a complicated periodic flow through acquisition of less data, but with closely controlled parameter variations.
