  神州十一号英语作文素材:

  Details: fly higher - 393 km altitude docking with the run

  Shenzhou 11 fully inherited the shenzhou 10 state of technology, at the same time in order to meet the mission requirements and have done many technical improvement.

  "To meet the requirements of the mission, adjusted the orbit control strategy and flight procedures, make the spacecraft shenzhou 11 can adapt to the mission orbit rendezvous and docking and return altitude increased from 343 km to 393 km." Wu Pingshui deputy director of the China manned space engineering office. 17, July 30 points, when the shenzhou manned spacecraft launch no. 11. Xinhua news agency reporter shih-ping liu was taken

  Shenzhou 10 dock with the tiangong 1, orbital altitude of 343 kilometers. And shenzhou 11 tiangong number two docking orbit at an altitude of 393 kilometers, is higher than in the past 50 km, why more than 50 km? Aerospace science and technology corporation, which is five yuan GNC subsystem command Luo Guqing said, mainly for China's manned space "three-step" development strategy to prepare the third step, build a sp良性癫痫发作症状ace station, because of this and future space station in the same orbit altitude, flight is more close to the future space station.

  Detail 2: longer space journey - 33 days

  Orbit shenzhou 11 after two days after the flight of independence, complete with tiangong 2 automatic docking assembly formation, mid 30 days to complete the assembly reside task, separated from heaven ii, in one day return to the main landing zone in Inner Mongolia, the shenzhou 11 end task. In space, time is long, how to guarantee the astronauts living and working space and the ability to perform a task, how to improve the reliability of spacecraft? Tiangong ii (image exhibition space 60 years)

  Shenzhou 11 technical improvement, an important innovation, is equipped with new wide beam trunking communications terminal equipment.

  "In order to further improve security, reliability, and the new is equipped with wide beam trunking communications terminal equipment, significantly expanded the measurement range, improves the rapid changes in spacecraft attitude and communication support ability, so as to improve the reliability of the safety of the astronaut and the spacecraft." Wu Pingshui.

  Detail three: upgrade optical imaging sensors - complete difficult "space kiss"

  "To test the future space technology, sa平顶山癫痫病医院有多少tisfies the requirement of the future space station intersection measuring equipment long life use, the shenzhou 11 intersection measuring equipment for the upgrade." Wu Pingshui.

  Tiangong number two and rendezvous and docking of the shenzhou number 11, is an important step to build the home of the space, especially both from 120 meters to the final completed stage, the most difficult, the highest risk. In order to make they can at 8 times the bullet speed down to docking together, technical personnel of optical imaging sensor to achieve the upgrade. Manned spacecraft shenzhou 11 module assembly (aerospace science and technology group provides the five yuan

  Rendezvous and docking shenzhou 11 designer, director of the optical imaging sensors Gong Dezhu said, the intensity of sunlight in space three to five times that of earth, it is easy to "blind" aircraft "eyes", just like when driving car is opposite to sway the headlight, need some time to restore vision, so want a choice of appropriate light before docking.

  Products and the use of the tiangong 1 generation compared to upgrade the sun sensor light inhibition, identify the target sensitivity were improved, even if be sway eye, vision recovery time can also be from the original 10 seconds to a few hundred milliseconds. And as a result, the shenzhou 11 tiangong 哪治癫痫好ii can realize the all-weather real-time docking, can guarantee the spacecraft emergency rescue service supply or an astronaut.

  Mid detail four: evaluation for the first time astronauts reside

  "The mission objective is to further the comprehensive validation on the modified function of manned spacecraft, manned mission to provide important technical support for the follow-up. In addition, through a number of on-orbit test, will further verify the spacecraft design function, acquisition and accumulation of manned flight test data of environmental related." The spacecraft shenzhou 11 chief designer Zhang Bainan said.

  Orbital docking with the mission to the space lab, and return to the altitude increased by 50 km than before, the shenzhou 11 tasks for the first time the inspection validation phase of rendezvous and docking station and the technology of manned spacecraft to return to, will also be mid-term examination for the first time an astronaut reside ability, by verifying the astronauts reside ability, laying a foundation for long-term on-orbit evaluation phase as an astronaut space station.

  细节一:飞得更高——393公里轨道高度的对接与运行

  神舟十一号充分继承了神舟十号的技术状态,同时为了适应本次任务要求而进行了多项技术改进。

  “为满足本次任务要求,调整了轨道控制策略和飞行程序,使神舟十一号飞船能够适应本次任务交会对接轨道和返回轨道高度由343公里提高到393公里的要求。”中国载石家庄什么医院能治癫痫病人航天工程办公室副主任武平说。17日7时30分,神舟十一号载人飞船发射升空。新华社记者刘诗平 摄

  神舟十号与天宫一号对接时,轨道高度是343公里。神舟十一号和天宫二号对接时的轨道高度是393公里,比过去高了50公里,为何要高出50公里?航天科技集团五院GNC分系统指挥罗谷清说,主要是为了我国载人航天“三步走”发展战略的第三步——建造空间站做准备,因为这与未来空间站的轨道高度基本相同,飞行也更加接近未来空间站要求。

  细节二:时间更长——33天的太空旅程

  神舟十一号入轨后经过两天独立飞行,完成与天宫二号自动对接形成组合体,完成组合体30天中期驻留任务后,与天宫二号分离,在一天内返回内蒙古主着陆场,神舟十一号任务结束。在太空时间长,如何保障航天员太空工作生活和执行任务的能力,怎样提高飞船的可靠性?天宫二号(航天60年展览图片)

  神舟十一号的技术改进,很重要的一个创新亮点,是新配备了宽波束中继通信终端设备。

  “为进一步提高安全性可靠性,新配备了宽波束中继通信终端设备,显著扩大了测控覆盖范围,提升了飞船姿态快速变化时的天地通信保障能力,从而提高了航天员的安全性和飞船的可靠性。”武平说。

  细节三:升级光学成像敏感器——完成高难度“太空之吻”

  “为验证未来航天技术,满足未来空间站交会测量设备长寿命使用要求,对神舟十一号的交会测量设备进行了升级换代。”武平说。

  天宫二号和神舟十一号的交会对接,是搭建太空之家的重要一步,尤其是两者从相距120米到最终完成对接的阶段,难度最大、风险最高。为了让它们能在以8倍于子弹的速度下毫厘不差地对接在一起,技术人员对光学成像敏感器实现了升级。 神舟十一号载人飞船轨道舱吊装(航天科技集团五院提供)

  神舟十一号交会对接光学成像敏感器主任设计师龚德铸说,太空中阳光照射强度是地球上的三到五倍,很容易“亮瞎”飞行器的“双眼”,就像开车时被对面来车晃了大灯,需要一段时间才能恢复视力,因此以往交会对接要选择光线合适的时机进行。

  与天宫一号上运用的一代产品相比,升级版敏感器的太阳杂光抑制能力、识别目标敏感度均大幅提升,即使被晃了眼,视力恢复时间也能从原来的十秒缩短到几百毫秒。由此,神舟十一号和天宫二号可以实现准全天候实时对接,可保障航天器突发维修补给或航天员应急救生。

  细节四:首次考核航天员中期驻留能力

  “此次任务目的是进一步对改进型载人飞船功能进行全面验证,为后续载人任务提供重要的技术支撑。此外,通过多项在轨试验,将进一步验证飞船设计功能,获取和积累载人环境相关的飞行试验数据。”神舟十一号飞船总设计师张柏楠说。

  在此次空间实验室任务中,对接轨道和返回轨道高度比以前增加了50公里,神舟十一号任务将首次考核验证空间站阶段的交会对接和载人飞船返回技术,还将首次考核航天员中期驻留能力,通过验证航天员驻留能力,为航天员空间站阶段长期在轨考核奠定基础。
