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.
