为了评估雷诺数对某大涵道比涡扇发动机的影响，利用 Wassell 等修正方法，对发动机主要部件的特性进行了雷诺数修正，并利用发展的性能仿真程序进行计算和对比。结果表明，在高空低马赫数下，雷诺数对大涵道比涡扇发动机性能影响较大，造成发动机的推力减小约1.98%、耗油率增大约3.04%，同时影响发动机的喘振边界及共同工作线，降低其可用稳定裕度。%For assessing the Reynolds number’s effect on a high bypass ratio turbofan,the correc-tion methods such as Wassell were used for the main component characteristics,and cooperated with a new performance program to simulate the effects of Reynolds number on engine’s performance.Re-sults show that Reynolds number has grievous effects on the turbofan in high flight and low Mach number region,the thrust is declined by near 1.98%,the specific fuel consumption is escalated by near 3.04%,the stall lines and operating lines are affected and the stall margin is declined as well.
