Pressure Measurements on the Rotating Blades of an Axial-Flow Compressor

Abstract
A rotor-mounted radio telemetry instrument system for measuring surface pressures on the rotating blades of an axial-flow compressor was developed and tested. The paper describes the design of the instrument system and several tests to establish its accuracy. Measurements of average and fluctuating surface pressures were reported. Measured pressure levels were found to agree with theory and available experimental data.
