摘　　要：介绍了飞机环境控制系统中发动机引气、热交换器、管道、文氏管以及阀门等部件的数学模型。在此基础上,采用分模块建模的思想,利用MATLAB/SIMULINK仿真平台开发了飞机环境控制系统计算机仿真模型库。所开发的模型库具有仿真速度快、通用性以及实时性好的特点。利用该模型库可任意构建飞机环控系统仿真模型,完整地仿真我国现行的飞机环境控制系统,并对其进行稳态及动态性能仿真计算。以某型飞机环境控制系统为例,利用该模型库构建了环控系统完整的全流量仿真模型,并给出稳态计算结果和动态响应分析。The mathematical model for aircraft engine, heat exchanger, duct, ventufi, valve and other components in aircraft environment control system （AECS） is described in this paper. Based on it, the computer simulation model library for AECS is established with module structure using software MATLAB/SIMULINK. The developed model library has many advantages as fast simulation speed, good common use and well real -time. AECS in China can be simulated by using model library at steady - state. The example of ACES full simulation model is spliced using the simulation model library and steady simulation result and dynamic process analysis is given in this paper.
