本文对最大状态下双转子发动机的双变量调节计划进行了讨论,用非线性模拟计算程序对双变量发动机进行性能计算,其结果是双变量涡喷发动机性能大大优于单变量调节计划的涡喷发动机。虽然有不同的二种性能参数组合的计划,但每种计划仅适用发动机的一种情况使用。当釆用具有相同的低压转子转速和相同的涡轮前温度的计划时,高压压气机的喘振边界将缩小,文中的一种复杂调节计划是解决困难的一种好方法。最后对双变量调节计划使用中遇到的问题进行了分析。
In this paper, the bivariate adjustment plan of dual-rotor engine under maximum condition is discussed. The performance of the bivariate engine is calculated by nonlinear simulation calculation program. The result is that the performance of the bivariate turbojet engine is much better than that of the univariate adjustment turbojet engine. Although there are different plans for a combination of two performance parameters, each plan applies only to one case of an engine. When precautions are taken with the same low-pressure rotor speed and the same pre-turbine temperature, the surge boundary of the high-pressure compressor will be reduced and a complex regulation scheme in the text is a good solution to the difficulties. Finally, the problems encountered in the use of bivariate adjustment programs were analyzed.
