飞机综合热能管理系统仿真分析

Simulation Analysis of Aircraft Integrated Thermal Management System

以某型飞机的综合热能管理系统为对象开展了研究。该系统以燃油作为主要热沉,使用热防护结构和液体蒸发器作为辅助热沉,对整机的热量进行综合调控及管理。建立了综合热能管理系统数学模型,在Flowmaster软件中搭建了系统的仿真模型进行计算。研究结果表明,提出的系统能满足飞机整体的热设计需求,为飞机综合热能管理系统及各子系统的设计提供参考。

This paper takes a integrated thermal management system as object of study.In this system,the main heat sink is fuel oil and auxiliary heat sink is thermal protection structure and liquid evaporator,which comprehensively control and manage the heat of the whole aircraft.The mathematical model of the integrated thermal management system is established,and the simulation model of the system is built in Flowmaster software for calculation.The results show that the system above can meet the overall thermal design requirements of the aircraft.A reference is given to the design of the aircraft integrated thermal management system and its subsystems.
