Data acquisition and analysis techniques for measurement of unsteady wall pressures in a transonic compressor
Abstract
Real-time acquisition and analysis techniques have been developed for the measurement of unsteady wall pressures in a transonic compressor. The report contains listing and explanatory notes for the computer codes and is intended as a guide to users of the system. Preliminary results are presented in the form of casing wall pressure contours. They demonstrate the effectiveness and versatility of the system in its ability to synchronize sampling of rapidly fluctuating signals with the rotation of the rotor.
