Simulation analysis on oxygen partial pressure control of multi-cabin manned spacecraft

  • 摘要: 为确保乘员安全性,载人航天器需通过氧分压控制系统将密封舱内的氧分压控制在指标范围内.提出了一种两舱段载人航天器密封舱氧分压控制系统数学模型,包括密封舱体、乘员、供氧组件、舱间通风(IMV)等多个子模块.通过与相关试验数据进行对比,证明了数学模型的准确性.针对由两个容积为60 m3密封舱组成的组合体,利用该模型分析了乘员驻留位置、舱间通风量、氧分压监测模式对两舱氧分压的影响.结果表明:当舱间通风量为0.5 m3/min 且6人驻留在氧分压非主控舱时,两舱氧分压上限差别达到2.2 kPa.两舱氧分压差别会随着舱间通风量的增加而减小.单舱监测模式和两舱监测模式对两舱氧分压影响并不显著,当舱间通风量超过1.5 m3/min时,两种控制模式的氧分压控制效果趋于一致.
