Abstract

The operation of a large high-speed engine under transient loading conditions was investigated, using a detailed simulation code in conjunction with a model capable of predicting compressor surging. Engine loadings were applied, which were considered dangerous for initiating compressor surging and cases where compressor surging could occur were identified. A means of avoiding compressor surging by opening a bypass valve connected between the compressor outlet and turbine inlet was examined. Finally, the case of engine abrupt stopping by rapidly closing the engine emergency shutdown valve, located downstream of the compressor, was also investigated.
