“一孩子和妈妈拔萝卜一起生孩子”陕西科技护航一孩子和妈妈拔萝卜一起生孩子天舟八号 为航天员“打包”太空“生活用品”

  中新一孩子和妈妈拔萝卜一起生孩子网西安11月16日电 (杨英一孩子和妈妈拔萝卜一起生孩子琦)11月15日23时13分,载着天舟八号货运飞船的长征七号遥九运载火箭从中国文昌航天发射场点火起飞,发射任务取得圆满成功。在此次任务中,中国航天科技集团四院(以下简称:航天科技四院)为天舟八号货运飞船提供了多种产品。飞船还搭载了由该院研制的吸附药盘及“太空卫生间”组件等产品,全方位为空间站和航天员提供细心呵护。

  由于太空条件极其苛刻,长期在轨工作对空间站动、静结构与机构的密封件使用寿命和性能都提出了更高要求。航天科技四院42所为飞船及空间站提供的所有动、静结构与机构密封件可以防止舱外的辐照,耐受空间环境各种严苛的考验,确保航天员的生命安全和舱内仪器仪表的正常运行,为航天员提供了可靠的长寿命密封防护。此外,由该院42所研制的吸附药盘及“太空卫生间”组件等也是航天员重要的“生活用品”。

  航天科技四院44所研制的两型温度传感器作为天舟八号货运飞船低温锁柜控温系统的核心元器件,为锁柜温度检测和控制提供了参数依据。该两种型号温度传感器具备体积小、重量轻、精度高、长期稳定性好以及空间环境适应性强等优点,为飞船的正常运行提供了可靠保障。

  随着天舟八号货运飞船一同被“打包”进太空“快件”中的,还有航天科技四院401所为问天实验舱提供的6组电机组件,包含步进电机、减速器、增速器等部件,应用于实验舱外机械臂的载荷适配器主动端机构中,通过电机组件的自动化控制,实现主动端和被动端的快速对接,为实验舱外开展大量暴露实验所需各类资源提供供给通道。

  据悉,此次天舟八号货运飞船携带了航天员在轨驻留消耗品、推进剂、应用实(试)验装置以及节日“大礼包”等约6吨的物资。此外,还搭载了备受关注的“月壤砖”样品,该样品将在轨完成舱外暴露实验。(完)
