载人运输飞船流体回路方案研究

流体回路是载人运输飞船热控分系统的重要组成部分,结合飞船所采取的其他热控措施,流体回路必须满足各种可能出现的热工况要求,同时尽量少占用飞船的资源。在进行分析和比较的基础上,确定流体回路的方案和系统配置,结合对接目标的热设计,重点解决与目标停靠期间的热控问题。文中介绍了载人运输飞船流体回路的主要设计要求及考虑重点,在能量平衡分析的基础上设计了两种流体回路方案,并进行了热分析计算和性能比较,对流体工质的选择也提出了建议。

Scheme of Fluid Loop System on Manned Spacecraft for Transport

The fluid loop is the most important part of the thermal control system on manned spacecraft.The fluid loop must meet the thermal requirement of all kinds of the conditions that may be occur during the whole period,working with other passive thermal control measure on spacecraft.At the same time,it should occupy the resource of the spacecraft as less as possible.The scheme and configuration of the fluid loop were determined basing on analysis and comparison.Considering the thermal design of target spacecraft to be docked with,the emphasis of the design was put on solving the thermal problems during the period of two spacecrafts combined together.The main requirements and emphases of designing fluid loop were presented.Based on the analysis of energy balance,two kinds of scheme were designed.And the performance of two schemes was compared.Finally,some suggestions on choosing working fluid of fluid loop system.
