摘要: 针对高性能战斗机的特点,介绍了利用燃油作为主要热沉的燃油热管理系统FTMS(Fuel Thermal Management System).以F-22的热管理系统为原型,在对其技术方案及研究方法进行了相关分析后,通过MATLAB工具建立了系统各部件的动静态仿真模块.并在此基础上,搭建了燃油热管理系统的仿真平台,利用该仿真平台对燃油热管理系统的性能及燃油代偿损失等进行预测和评估.计算结果表明,燃油热管理系统性能要好于传统的空气循环制冷系统,在热管理方面可作为我国新一代高性能飞机设计研究的一个备选方案.Abstract: For improving the character of high-performance fighter aircraft, fuel thermal management system (FTMS) was put forward. FTMS uses fuel as the main heat sink of environmental control system (ECS) and other systems which need to be cooled. Thermal management system of F-22 fighter aircraft is a typical applied case. Taking F-22 FTMS as an original version, the research method of thermal management system were analyzed. By using MATLAB simulation tools and S-function, static simulation and dynamic simulation modules of the system components were built up in order to get the simulation platform of FTMS. This platform could estimate the system performance and the fuel penalties. The simulation results show that FTMS can work better than the air cycle system (ACS) and satisfy the needs of high-performance fighter aircraft. FTMS will be one of the options for designing thermal management system of high-performance fighter aircraft.
