在“神舟七号”执行中国航天员首次太空行走任务过程中,最大的亮点之一就是翟志刚穿的我国自己研制的“飞天”舱外航天服。其质量为120千克,单套价值高达3000万元人民币,可靠系数为0.997,可支持至少4小时的舱外活动,能重复使用5次以上,服装气体泄漏率不大于2升/分钟;应急供氧时间不小于30分钟;平均散热量为300瓦。为满足航天员在太空活动的需要,“飞天”和美俄舱外航天服一样,具有供氧、温控、二氧化碳吸收等环境控制、生命保障与安全防护功能,具备信息采集传输、通信能力,同时能满足人机工效要求。该
One of the biggest bright spots in the implementation of the first spacewalk mission for Chinese astronauts on the “Shenzhou VII” was Zhai Zhigang’s own spaceflight suit developed by China. The quality of 120 kg, single set value up to 30 million yuan, the reliability factor of 0.997, can support at least 4 hours of extravehicular activities, can be reused more than 5 times, clothing gas leakage rate of not more than 2 liters / minute; Oxygen time is not less than 30 minutes; the average heat dissipation is 300 watts. To meet the needs of astronauts in space activities, “Flying Sky” has the same functions of environmental control, life support and safety protection as oxygen and temperature control and carbon dioxide absorption in the United States and Russia as well as information collection and transmission and communication capabilities , While meeting ergonomic requirements.
