Extension of Useful Operating Range of Axial-Flow Compressors by Use of Adjustable Stator Blades

Abstract

A means for increasing flow range of axial flow compressor by resetting of both rotor and stator blades or resetting stator blades alone was investigated. Tests were conducted with design blade setting and stator blades reset for 75% of design speed for load coefficients of 0.48 and 0.65. Peak pressure ratios were increased with stator blades reset for load coefficients of 0.65. Adjustment of stator blade angles only improves peak efficiencies below design speed and, by use of different blade settlings, the flows for peak efficiency can be varied.
