Rapid Simulation Platform for Integrated Thermal Management System of High-speed Aircraft

高速飞行器面临严峻的外部气动热和内部设备热环境,以热防护系统和热管理系统组成的综合热管理方案决定该类飞行器总体方案的闭合性,因此需要在飞行器初步方案设计阶段对综合热管理系统设计方案进行快速仿真计算和可行性评估。以电子设备舱为例,采用模块化设计和一维简化方法,构建一个将飞行器热源、传热和热控等热环境因素进行模块化封装的快速仿真平台;通过仿真算例对该平台进行验证。结果表明:该平台可以快速实现飞行器电子设备舱综合热管理方案的模型搭建、计算与评估。

Facing severe aerodynamic and inner equipments’heat environment,the integrated thermal management platform composed of thermal protection system and thermal management system decides the closed performance of aircraft overall scheme,so the preliminary design scheme of integrated thermal management system which determines the feasibility of aircraft design needs to be rapidly simulated to judge its feasibility in the aircraft design stage.Taking electronic equipment cabin as an example,the fast simulation platform using modular design and one-dimensional simplification method is built by modularly packaging of heat source,heat transfer,thermal control and other simulation components,and is verified with simulation instance.The results show that the platform can quickly realize the model establishment,simulation and evaluation of aircraft electronic equipment cabin integrated thermal management scheme.
