FATIGUE TESTS AND CRACK DETECTION ON SOME TYPES OF AXIAL FLOW COMPRESSOR ROTOR BLADES

Abstract

Fatigue data were obtained from several types of compressor rotor blades that are in use in axial-flow compressors at the von Karman Gas Dynaics Facility. The data provided a general comparison of ''as manufactured'' endurance limits and were used as a veification control in evaluating a supplemenary method of detecting failed blades during sytematic maintenance inspections. By the presentation of stress versus cycles to failure curves, a comparison is ade between AISI number-8630 cast steel blades as originally furnished with the compressors, AISI number-8630 cast steel shot-peened blades, and AISI number-403 forged, heat-treated and machined blades. A method is presented which may be used to supplement the magnetic particle method for detecting cracked rotor blades.
