摘　　要：研究运输机供氧系统,建立相应的系统仿真模型,对整个管网系统中氧气的流动及分配进行仿真分析.系统由高压氧源、机组供氧点和座舱乘员供氧点3部分组成,各部分分别建模,然后集成系统;为了方便设计者针对不同的管路布置进行系统仿真分析,利用Flowmaster的外部元件模块开发出了氧气系统特有的元件,包括氧气调节器、减压器和快戴式氧气面罩;在某任务航程下利用此仿真模型对氧气系统进行了仿真计算,得到各气瓶耗氧量和各供氧点氧气流量的变化情况,验证了系统是否满足设计需求.Transport aircraft oxygen system was discussed,and a computer analysis model of oxygen system was established in order to analyze the flow and distribution of oxygen in the whole pipeline network.This system was comprised of three parts.They were high pressure oxygen source,aircrew oxygen supply points and cabin oxygen supply points.Separate models were established before the single system.Several special components of oxygen system were created using the external component models in Flowmaster,including the oxygen regulator,pressure reducer and quick-don oxygen mask.It made the designer more convenient to create new system models for different pipeline networksdesign.A computer analysis of the oxygen system was also performed with a given flight assignment using this analysis model,and the simulation results show the oxygen consumption and the flow rate of each oxygen supply points.It was used to verify that the system meets the design reguirements.
