| 摘 要： | 转差是双轴发动机台架验收的参数之一，它表明该发动机的高压转子换算转速ｎ２和涡轮前燃气换算温度Ｔ３的关系，并间接地反映了高低压转子的匹配关系。一个机种型别应有标准的转差线，用以确定具体的每台发动机的转差值。本文分析了多种可能的转差线的计算途径，并提出在实践中如何确定转差线的方法。

| Abstract: | The revolution difference of the low and high pressure rotors is a parameter for acceptance tests of a twin-spool turbojet engine.It indicates the relation between the reduced revolution of the high pressure rotor and the reduced turbine inlet temperature and also shows the matching between the low and high pressure rotors.In order to determine the revolution difference for a twin-spool turbojet engine it is necessary to define a standard revolution difference line for this type of engine.This paper analysis considers various possible approaches for the revolution difference line computation and suggests how to define the standard revolution difference line in practice. |
