摘　　要：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。Aero-engine digital simulation is the integrated application in the field of aircraft engine with modern information system simulation and the latest scientific achievements.Based on the FORTRAN77 procedure,a mathematical model of the double-shafts turbojet engine was established.First of all,the design point's performances of a two-axle turbojet engine were calculated.The calculations of off-design points were based on the control law of low pressure rotor speed at 11212r/min.By the use of FORTRAN procedure,the performance parameters of the engine at maximum working condition are obtained.Meanwhile,a certain double-shafts turbojet engine's speed characteristics,height characteristics as well as throttle characteristics were analyzed.The calculation yields in a large content matched very well with the actual performance data of the double-shafts turbojet engine.
