摘要
应用航空发动机总体性能计算程序,分析了部件性能变化对大涵道比、双转子涡轮风扇发动机总体性能的影响。在几个典型转速下,对比分析了某型大涵道比发动机部件效率降低及流路总压损失增大后发动机台架性能的变化,确定了影响发动机推力、耗油率、排气温度以及压缩部件稳定性的关键因素。
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.
