Over the past three decades, great advances have occurred in the theoretical appraisals which can be made of gas turbine engine components. Nevertheless the amount of mechanical testing done on such pieces has not declined but has become more extensive and detailed. Major rotating components, whose failure is potentially catastrophic to an aircraft, are the concern of much of this testing, which is aimed at proving and developing the mechanical strength or endurance of the piece. This paper briefly reviews the principal tests, the techniques and some of the equipment which is employed at Rolls-Rocye, Derby, for testing compressor and turbine components. The work relates to about ten different engine types, including the RB 211 family of engines, and to both civil and military applications. A considerable amount of research work also forms part of the activity. (Wassmann)
