航空发动机数字仿真是现代系统仿真和信息科学等领域最新成果在航空发动机上的综合应用。用Fortran77程序建立了某型飞机双轴涡喷发动机的数学模型,对发动机非设计点计算以低压转子物理转速n1=11 212 r/min为控制规律,利用Fortran程序求得发动机在最大状态时的性能参数,并对双轴涡喷发动机的速度特性、高度特性以及节流特性做了简要的分析。计算结果和某型飞机双轴涡喷发动机实际性能数据作比较,在大多数情况下吻合良好。
Aeroengine digital simulation is the modern system simulation and information science and other fields in the latest achievements in the integrated application of aeroengine. Fortran77 program was used to establish a mathematical model of a twin-turbojet engine. Based on the control law of the non-designed point of the engine with the low-pressure rotor physical speed n1 = 11 212 r / min, the Fortran program was used to calculate the maximum Performance parameters, and the biaxial turbojet engine speed characteristics, height characteristics and throttle characteristics made a brief analysis. The calculated results are compared with the actual performance data of a certain type of twin-turbo turbojet engine and agree well in most cases.
