神州十一號英語作文素材:
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 space 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, satisfies 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 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.

細節(jié)一:飛得更高——393公里軌道高度的對接與運行
神舟十一號充分繼承了神舟十號的技術狀態(tài),同時為了適應本次任務要求而進行了多項技術改進。
“為滿足本次任務要求,調整了軌道控制策略和飛行程序,使神舟十一號飛船能夠適應本次任務交會對接軌道和返回軌道高度由343公里提高到393公里的要求。”中國載人航天工程辦公室副主任武平說。17日7時30分,神舟十一號載人飛船發(fā)射升空。新華社記者劉詩平 攝
神舟十號與天宮一號對接時,軌道高度是343公里。神舟十一號和天宮二號對接時的軌道高度是393公里,比過去高了50公里,為何要高出50公里?航天科技集團五院GNC分系統(tǒng)指揮羅谷清說,主要是為了我國載人航天“三步走”發(fā)展戰(zhàn)略的第三步——建造空間站做準備,因為這與未來空間站的軌道高度基本相同,飛行也更加接近未來空間站要求。
細節(jié)二:時間更長——33天的太空旅程
神舟十一號入軌后經(jīng)過兩天獨立飛行,完成與天宮二號自動對接形成組合體,完成組合體30天中期駐留任務后,與天宮二號分離,在一天內返回內蒙古主著陸場,神舟十一號任務結束。在太空時間長,如何保障航天員太空工作生活和執(zhí)行任務的能力,怎樣提高飛船的可靠性?天宮二號(航天60年展覽圖片)
神舟十一號的技術改進,很重要的一個創(chuàng)新亮點,是新配備了寬波束中繼通信終端設備。
“為進一步提高安全性可靠性,新配備了寬波束中繼通信終端設備,顯著擴大了測控覆蓋范圍,提升了飛船姿態(tài)快速變化時的天地通信保障能力,從而提高了航天員的安全性和飛船的可靠性。”武平說。
細節(jié)三:升級光學成像敏感器——完成高難度“太空之吻”
“為驗證未來航天技術,滿足未來空間站交會測量設備長壽命使用要求,對神舟十一號的交會測量設備進行了升級換代。”武平說。
天宮二號和神舟十一號的交會對接,是搭建太空之家的重要一步,尤其是兩者從相距120米到最終完成對接的階段,難度最大、風險最高。為了讓它們能在以8倍于子彈的速度下毫厘不差地對接在一起,技術人員對光學成像敏感器實現(xiàn)了升級!∩裰凼惶栞d人飛船軌道艙吊裝(航天科技集團五院提供)
神舟十一號交會對接光學成像敏感器主任設計師龔德鑄說,太空中陽光照射強度是地球上的三到五倍,很容易“亮瞎”飛行器的“雙眼”,就像開車時被對面來車晃了大燈,需要一段時間才能恢復視力,因此以往交會對接要選擇光線合適的時機進行。
與天宮一號上運用的一代產(chǎn)品相比,升級版敏感器的太陽雜光抑制能力、識別目標敏感度均大幅提升,即使被晃了眼,視力恢復時間也能從原來的十秒縮短到幾百毫秒。由此,神舟十一號和天宮二號可以實現(xiàn)準全天候實時對接,可保障航天器突發(fā)維修補給或航天員應急救生。
細節(jié)四:首次考核航天員中期駐留能力
“此次任務目的是進一步對改進型載人飛船功能進行全面驗證,為后續(xù)載人任務提供重要的技術支撐。此外,通過多項在軌試驗,將進一步驗證飛船設計功能,獲取和積累載人環(huán)境相關的飛行試驗數(shù)據(jù)。”神舟十一號飛船總設計師張柏楠說。
在此次空間實驗室任務中,對接軌道和返回軌道高度比以前增加了50公里,神舟十一號任務將首次考核驗證空間站階段的交會對接和載人飛船返回技術,還將首次考核航天員中期駐留能力,通過驗證航天員駐留能力,為航天員空間站階段長期在軌考核奠定基礎。
