| Abstract: | The effect of component performance variation on the performance of high bypass ratio double-spool turbofan engines on testbed was analyzed by the overall performance calculation procedure. In several typical speed conditions, the variation of performance a high bypass ratio engine on testbed after the component efficiency drop and the flowpath total-pressure lossrise was analyzed. The key factors of the influence of thrust, specific fuel consumption, EGT and the stability of compressed components were defined. |
