On May 17, 2019 23 when 48 minutes, chang Weixing launchs a center on the west, as blare, long march 16 rockets of 3 third Yao unplug the ground and case, howl is worn bear down on canopy, fight north navigation satellite to send successfully book orbit. This the success of the task indicates place belongs to a limited company of group of spaceflight science and technology academy of technology of Chinese carrier rocket (courtyard of rocket of the following abbreviation) the rocket finished the long march series that stresses total development the 200th times to blast off. Chinese spaceflight person again with perfect expression, to urge spaceflight powerful nation construction gave in an excellent exam paper.

49 years finish 200 times blast off
Since nearly half century, the carrier rocket technology of Chinese spaceflight obtained great progress. Regard the dominant of industry of Chinese spaceflight science and technology as force, rocket courtyard manufactured the carrier rocket of long march series of 12 kinds of different type independently early or late, from on of century middle period do poineering work difficultly, approach a month to the flight holding a person at the beginning of this century, oneiromancy, arrive again some closer year high density blasts off, industrialization develops, long march rocket came true from do not have have, arrive from series connection bind, from " one arrow one star " to " one arrow much star " , wait to emissive manned airship and moon detector from emissive satellite a series of great span.
49 years, rocket courtyard was finished 200 times in all blast off, among them the first shoot last a period of time 100 times nearly 41 years, the 2nd shoot last a period of time 100 times more than 8 years, aid pushed Chinese spaceflight to achieve milestone of 3 marks sex:
In April 1970, long march success of a carrier rocket will be Oriental red a satellite launchs close ground orbit, those who pulled open Chinese aerospace times is prelusive.
In November 1999, 2 F rocket launchs long march successfully divine boat experiments one number airship; October 2003, our country Yang Liwei of the first spacefarer sends aerospace, make the state that China becomes technology of manned spaceflight of the 3rd own development.
October 2007, long march 3 armour carrier rocket is successful China first moon explores a satellite " goddess in the moon " send book orbit, indicate the career crosses a Chinese spaceflight to explore new field into deep space.
Introduce according to Li Minghua of secretary of rocket courtyard Party committee, the rocket that rocket courtyard stresses total development aided force to finish carry month of person, visit, north to fight wait for a series of major projects. Among them, 2 F rocket finishs long march 13 times early or late manned spaceflight task blasts off, send aerospace successfully 14 person-time spacefarer; 7 carrier rocket finish long march Tian Zhou blast off, to the space that defend is worth for a long time in course, somebody the station builds next dozen of solid bases; Rocket of 3 armour series finishs long march 4 times visit month aircraft blasts off, aid force north to fight navigation system construction, finish all 48 north fight 36 arrows navigation satellite blasts off.
In addition, successful still will high resolution is opposite rocket of long march series meteorological satellite of series of ground observation satellite, wind and cloud and broadcast telecommunication satellite send book orbit.
Long march rocket is familial implementation whole replacement
Of the party 18 big since, regard Chinese spaceflight as the cradle of the birthplace of the career and long march carrier rocket, in the time that came to was less than 14 months on November 3, 2016 on September 25, 2015, rocket courtyard finished long march of new generation carrier rocket early or late 11 date, long march 7 date, long march 5 head fly. "3 model the successful development of carrier rocket and application of great devoted project, not only large-scale promoted our country the own, capability that enters an airspace quickly, and realized the integral replacement with long march familial rocket successfully, the end that means our country to face powerful nation of construction world spaceflight strode again one stride. " Li Minghua expresses.
With long march 7 rockets are exemple, development group was broken through early or late send 12 when be a delegate grand keys with be being measured new power, new position, new environment, new structure, new system, newly technology and 96 crucial technologies. Long march is Chinese spaceflight uses complete digitlization method first times 7, use completely three-dimensional in coordination, emulation experiment of number of design, general assembly and digitlization fire finished rocket, blueprint of a piece of paper quality is done not have in developing technological process completely. According to long march Wang Xiaojun of commander in chief of 7 carrier rocket introduces, this " digital rocket " still applied " virtual reality technology " , undertake to the rocket fictitious assemble and fictitious experiment, true imitate is assembled actually and experiment environment, ensure the rocket experiments, assemble " become " .
On November 3, 2016, long march of carrier rocket of new generation of the biggest thrust is in our country 5 numbers emissive field of spaceflight of Hainan article prosperous blasts off successfully -- this action is indicating implementation of our country carrier rocket upgrades replacement, locomotive ability enters international to have a kind first.
Regard the exclusive solid in carrier rocket of series of our country long march as carrier rocket, 11 carrier rocket have expedition emissive preparation time short, emissive cost is low advantage, a be spaceflight of our country commerce " fresh troops " . According to long march golden Xin introduces assistant general director of 11 carrier rocket, this model rocket from 2015 head since flying, revealed the high quality of the rocket and high reliability through blasting off successfully 6 times continuously, still will undertake the sea is performed this year show test and verify to experiment.
World top-ranking echelon formation is stridden before 2030
The footstep that explores outer space as the mankind is ceaseless and outspread, deep space holding a person explores the significant progress way that makes prospective spaceflight. Current, the country such as beautiful, Russia already restarted heavy-duty carrier rocket develops a plan, china needs the carrier rocket of greater ability likewise.
Diameter of body of core class arrow is 9.5 meters of class, close locomotive capacity reachs ground orbit 50 tons 140 tons, locomotive capacity reachs orbit of move approaching a month 15 tons 50 tons, locomotive capacity reachs orbit of move going straight towards fire 12 tons 44 tons... at present, long march is familial in the fresh blood that gets attention fully -- 9 heavy-duty carrier rocket are beginning long march crucial technology deepens argumentation to work. "Long march will become our country 9 numbers locomotive ability is the greatest one model rocket, of this project carry out science and technology of will farther stimulative spaceflight and industrial development, make the carrier rocket of our country strides world top-ranking echelon formation before 2030. " Zhang Zhi of total stylist of 9 carrier rocket expresses long march.
Combinative future spaceflight expands demand, rocket courtyard will rely on the reliable technology of new generation carrier rocket, union already had the successful experience of carrier rocket of long march series, prepare long march 8 carrier rocket, mix in order to make up for our country active service carrier rocket in sun synchronism orbit the empty shelves on emissivity of earthly synchronism orbit, reduce cost hard, enhance product market competition ability, fast track traffic projects the demand of the market in contented future. "We still were begun can duplicate research of technology of use carrier rocket, include an umbrella to fall reclaim and perpendicular case fall technology, finished partial experiment test and verify, a few crucial technologies obtain a breakthrough, develop lift form of characters or letters clearly to repeat use locomotive implement ' 3 paces go ' development train of thought. " Li Minghua discloses.
