摘　　要：本文通过对气源系统调压关断活门、风扇活门以及预冷器等参数特性的匹配,仿真计算了飞机在不同状态及引气构型下系统的性能特性,得到预冷器的换热特性参数、引气高压导管内和各部件内的流速以及压力损失,并对仿真计算结果进行评估,得出以下结论:高压导管内的流速满足设计要求,同时系统的性能满足引气温度及压力的控制要求,系统部件满足设计要求。Based on the selected performance of PRSOV,FAV and pre-cooler, simulation analysis has been done under the conditions of various aircraft states and bleed configurations to acquire the thermal performance of precooler, the internal flow speed and pressure drop distribution at different components. The results show that： the internal flow speed of the high pressure ducting can meet the design requirements and the system performance can meet the requirements of temperature and pressure regulation, also the components of pneumatic system can meet the design requirements.
