航天器热控回路的质量全局优化

Global mass optimization of spacecraft thermal control loop

为了减小载人航天器热控和环境控制生命保障系统的质量 ,在建立的单回路和内外耦合回路流动换热和质量构成的物理数学模型基础上 ,对系统进行了全局轻量化的计算和分析。结果表明 :系统质量全局优化结果不同于其局部优化结果 ;综合考虑各种影响因素 。

Global optimization of the governing equations for the flow and the heat and mass transfer in single loop and dual loop systems was used to reduce the mass of a spacecraft thermal control system and the environmental control and life support system. The results show that the globally optimum solutions differ from the local solutions. Integrated consideration of all influential factors is needed to minimize the mass. The mass can be greatly reduced using global mass optimization.
