Pressure-distribution Measurements on the Rotating Blades of a Single-stage Axial-flow Compressor

A preliminary investigation has been made of the pressure distribution about the mean-radius section of the rotating blades of a single-stage axial-flow compressor at a blade Mach number of 0.35. A 24-cell pressure-transfer device used in obtaining the pressure data is described and the accuracy of these data is established by several independent methods.
