防冰系统导管是飞机空气导管系统的重要组成部分,承担着为飞机机翼输送高温高压气体的重要任务。防冰系统导管内的传热和流动特性是飞机空气导管设计的关键问题。本文在研究防冰系统工作原理的基础上,基于一维流体仿真技术建立了某型飞机防冰系统导管的整体仿真模型,并对其进行了稳态分析和瞬态分析,得到了飞机防冰系统传热流动的仿真计算结果,同时考察了系统中各主要元件及节点的传热和流动特性,并对结果做了详细分析,结果表明在现有工况下防冰系统运行正常。该研究工作对于我国大型客机防冰系统的设计优化具有参考价值。
An anti-icing system duct is an important part of the air duct system of an aircraft and undertakes the important task of transporting high-temperature and high-pressure gas to the aircraft wing. The heat transfer and flow characteristics within the anti-icing system duct are key issues in the design of the air duct for the aircraft. On the basis of researching the working principle of anti-ice system, the whole simulation model of the anti-icing system duct of a certain aircraft is established based on the one-dimensional fluid simulation technology. The steady state analysis and transient analysis of the anti- At the same time, the heat transfer and flow characteristics of the main components and nodes in the system were investigated. The results were analyzed in detail. The results show that the anti-icing system is operating normally under the existing operating conditions. The research work has great reference value for the design optimization of large-scale passenger aircraft anti-icing system in our country.
