Address: China's "long March family" adds new Ding (map)

On June 25, a new generation of carrier rocket long March, seventh in Wenchang, Hainan spaceport blasted. News agency Xinhua Hong Jianpeng photo video: Multi-angle camera to record long seventh launch source: China News Network
25th in China's first spaceport to be built close to the sea, stretching half a century of "long March family" of taboo.
"Newcomer" named "long seventh", "standing" 53.1 m, equivalent to 20 stories high; a takeoff weight of 597 tons, the equivalent of 8 Chinese C919 large aircraft takeoff weight, because the design is reasonable, fueled more than 90%.
Shortly after birth, "the long seventh" topped in the family. For example, its stature has not selected family "first three", but its near-Earth orbits carrying capacity of 13.5 tons, far exceeding other rockets; as it again using the new event launch platform, is launched in China now accounts for the least amount of rockets.
Rocket, China Aerospace Science and technology group, a long seventh Deputy Commander Zhang goes on and says "children" advantages: the rocket's "brain" more precise, equipped with satellite positioning receiver, like "clairvoyance", green-friendly and affordable "big heart" ... ...
If sorted by advent, "the long seventh" coincidentally "seven". Since April 24, 1970, the long March launch vehicle, first launched, there have been "two", "three", "four", "six", "long and 11" was born, some of which are derived from a variety of improvements. Overall total 229 launches.
The reporter learns, "the long March family," according to project time "name". But due to the development of different, birth order has changed. Various types of rockets involved with each other, and carry out their duties.
"The long seventh," for example. 2011 project code name was "long-hair second-f", "the long seventh" and "long second" relationship closely. "Two f" has 10 Chinese Shenzhou series of spacecraft and the 10 astronauts safely to space, "up to seven" are complementary to by cargo ship, improve the ability of China's manned space presence in the rail testing.
"The long March family," founder of the China Aerospace Science and Technology Corporation for "long seventh" plan recently Laden, long-term manned; variety of variants, full coverage. They said that by 2021, when "the long seventh" when the technology to stabilize about 80% 's launch, China will assume the task.
Debut hit "one arrow 20 stars" record "long sixth", and launches a new generation of large carrier rocket for the first time in 2016 "long fifth", and "long seventh" succession. With you "brother" is a liquid rocket is different, the new four-stage solid rocket "March 11th" business as unusual, can be realized within 24 hours of the quick launch.
There have not yet been officially "ranks" family but had to make "heavy". One is a new solar synchronous orbit rocket "March eighth": the Secretary-General of the China National Space Administration Tian Yulong referred to May 26 in the NASA media briefing "represented by the long fifth rocket breaking the new engines and a series of key technologies drive the long sixth and long seventh, long eighth series of development." This is the first official in the formal occasions mentioned "March eighth".
Another is speculation and not official confirmation of "long Nineth", meaning rocket takeoff thrust 3000 tons capacity, near-Earth orbit in about 100 tons of heavy launch vehicle. Yang Baohua, Deputy General Manager of China Aerospace Science and technology group interviewed said that the China heavy launch vehicle completed further argues that the blueprints for heavy launch vehicle rocket in a diameter of nearly 10 meters, arrows with a total length of nearly hundred metres of an existing rocket carrying capacity, capacity is 5 times more than doubled. They plan to four or five years to break through a series of key technologies, and if all goes well, within 15 years is expected to achieve flight.
Yang Baohua said China will target the world's cutting-edge technology trends, Air launch vehicles, reusable launch vehicles and other more advance research in frontier technology, which means "long March family" were but more prosperous.

通讯：中国“长征家族”又添新丁(图)

　　25日在中国首个临海而建的航天发射场，已绵延半个世纪的“长征家族”添丁。

　　“新丁”名为“长征七号”，“身高”53.1米，相当于20层楼高；起飞重量597吨，相当于8架国产大飞机C919的起飞重量，因为设计合理，燃料比重超过90%。

　　甫一出世，“长征七号”就在家族里拔得头筹。比如，其身量虽未入选家族“前三”，但其近地轨道运载能力达到13.5吨、远超其他火箭；再如它采用新型活动发射平台，是目前中国发射占位最短的火箭。

　　中国航天科技集团一院长征七号火箭副总指挥张涛滔滔不绝地说起“孩子”的优点：火箭的“大脑”更加精准，配备的卫星定位接收机好比“千里眼”，选用绿色环保又经济实惠的“大心脏”……

　　若按问世年月排序，“长征七号”恰好也是“行七”。自1970年4月24日长征一号运载火箭发射以来，先后有“长二”、“长三”、“长四”、“长六”、“长十一”诞生，其中一些又衍生出各种改进型。全员累计完成229次发射。

　　记者获悉，“长征家族”的确按照立项时间“起名”。但因研制难度不同，出世顺序有变。各型火箭彼此间既有牵连、又各司其职。

　　以“长征七号”为例。2011年立项之初的代号是“长征二号F换发型”，可见“长征七号”与“长征二号”的关系之紧密。“长二F”已将中国10艘神舟系列飞船和10名航天员安全送到太空，“长七”则将通过货运飞船与之形成互补，提高中国载人航天在轨驻留试验能力。

　　“长征家族”的缔造者中国航天科技集团已为“长征七号”进行规划：近期载货，远期载人；多种改型、全面覆盖。他们说，预计2021年当“长征七号”各项技术趋于稳定时能够承担起中国80%左右的发射任务量。

　　首次亮相便创“一箭20星”纪录的“长征六号”，以及即将在2016年内首次发射的新一代大型运载火箭“长征五号”，将与“长征七号”一同接班。与诸位“兄长”是液体运载火箭不同，新型四级固体运载火箭“长征十一号”另辟蹊径，能实现24小时内的快速发射。

　　还有两位尚未正式“位列”家族却不得不提的“重磅人士”。一位是新型太阳同步轨道火箭“长征八号”：中国国家航天局秘书长田玉龙5月26日在国家航天局媒体通气会上提到“以长征五号运载火箭为代表突破了新型发动机等一系列关键技术，带动长征六号、长征七号、长征八号等系列化发展”。这是中国官方首次在正式场合提及“长征八号”。

　　另一位是外界猜测而未得到官方证实的“长征九号”，即指火箭起飞推力在3000吨上下、近地轨道运载能力在100吨左右的重型运载火箭。中国航天科技集团副总经理杨保华在受访时说，中国重型运载火箭已完成深化论证，设计蓝图中的重型运载火箭箭体直径近10米、全箭总长近百米、运载能力是现有火箭运载能力的5倍多。他们计划通过四五年时间突破一系列关键技术，如果进展顺利，15年内有望实现首飞。

　　杨保华说，中国也将瞄准世界前沿技术发展趋势，开展空射运载火箭、可重复使用运载火箭等更为前沿技术领域的预研，这意味着“长征家族”人丁更加兴旺。
