载人航天器密封舱内一氧化碳安全控制

Control of carbon monoxide density in the sealed cabin of manned spacecraft

  • 摘要: 载人航天器密封舱内由于火工品点火工作、非金属材料使用等原因将导致舱内一氧化碳的浓度升高,对航天员的生命安全带来较大威胁。文章分析了载人航天器密封舱内一氧化碳的产生来源,提出了非金属材料控制、火工品泄漏控制、净化通风等控制措施,并通过试验验证了措施的有效性,可供后续载人航天器舱内环境控制借鉴和参考。

     

    Abstract: In a sealed cabin of the manned spacecraft, the nonmetallic materials in the pyrotechnic ignition process may lead to a rise of the carbon monoxide density inside the chamber, as a hazardous situation for the crew. Based on the analysis of the origin of the carbon monoxide, many countermeasures are proposed, such as the control of the nonmetallic materials, the limiting of the leakage rate, and the adequate ventilation and purification. The above measures are tested for their effectiveness, and they may be used for the subsequent engineering design.
