摘　　要：为准确模拟飞机导管引气系统在各工况下的运行状态,在研究飞机引气系统结构及流体网络算法原理的基础上,基于—维流体仿真技术建立了引气系统计算模型,根据实际工况对系统进行了稳态和瞬态分析。重点考察了系统中各主要元件的运行情况及节点的压力、温度等关键参数的变化规律。仿真结果表明,系统及各主要元件均满足设计与控制要求,可为我国民用客机导管系统的优化设计提供一定的理论参考。For accurate simulation of bleed system＇s operating states under every operating conditions, a computation model is developed by means of one dimension lumped parameter technology based on the principle of Bleed air system and fluid network algorithm. Then system steady state and transient analysis is proceeded. Operating conditions of main components as well as thermal and flow behaviors, such as temperature and pressure of nodal point, are especially investigated. And the simulation results indicate that the system and main components all meet the design and control requirements. Reference value is provided for design and optimization of China＇s civil-aircraft ducting system.
