| 摘 要： | 现代飞机环控系统一般由压气机、涡轮和多个换热器组成,结构复杂,热惯性大,对干扰和调节作用的响应较为复杂,不便于理论分析.因此采用差分方程、线性回归等方法建立了换热器、涡轮、压气机等附件及系统整体的动态数学模型,并应用于一种国际上较为先进的飞机环控系统--动力涡轮驱动的闭式空气循环系统的仿真计算.初步分析了该系统的扰动特性、调节特性和控制规律.

| Abstract: | Modern aircraft environmental control system (AECS) is composed of compressor turbine and several heat transfers. The system is complicated and has large heat inertia. Differential equation and linear regression and other math method were applied to building the dynamic model of each part and system of AECS. The model is introduced in simulation of an advanced high temperature, turbine powered bootstrap AECS. The dynamic response and control rule of the system were analyzed by this model. |
