585 seconds! Decrypt rocket launch | Temple _ the whole process news
CCTV News (reporters Wang Xiaoying Wang Jiazhu) 22:04 P.M., at the Jiuquan Satellite Launch Center in China launch second space laboratory, assume control of launch is a long second-f rocket.
It is understood that the long second f rocket are divided into two levels, the rocket took off, it weighed close to 500 tons, of which 90% are liquid fuel weight. One-stage, two-stage rocket as well as four booster rockets strapped like six giant fuel tank filled with fuel for the rocket to provide strong power. In order to make the rocket parachute, six fuel tanks will be thrown away after the fuel runs out.
F, long second temple on the second rocket into orbit, the whole process takes approximately 585 seconds. In less than ten minutes, "temple on the second" long March rocket put on a flying large second-f rocket has completed its mission, followed by separation, the last Temple on the second into space.
Aerospace Science and technology group, a long second f Jing muchun, Chief Designer of the rocket to decrypt the whole process of the rocket launch to the media.
12 seconds after takeoff, the rocket will no longer fly straight up, but turn a corner, along the Earth's inclination to fly to save on rocket fuel, this action is called a procedure turn. After turning, the base along the direction parallel to the Earth's orbit.
Flights to 155 seconds, four booster rocket fuel runs out, away from the rocket.
For 160 seconds, a rocket fuel, one or two stage separation, rockets II engine starting.
210 seconds, two-stage rocket with the temple fly out of the atmosphere, top fairing to protect spacecraft ended its mission, also was thrown out by rockets. 582 seconds, the rocket after the second stage engine fuel exhaustion stopped working. Three seconds later, arrow Board separation, will heaven send rockets into orbit, the rocket's mission ended.
As China's manned space project "exploits the rocket", from 1999 to 2013, 11 long-second-f rocket "relay" launch, successful launch of "Shenzhou first" to "Shenzhou tenth" spaceship and "temple on the first" target aircraft, the 10 astronauts into space, rate 100% and Chinese nation of the Millennium Round "flying dreams".

585秒！解密火箭发射天宫全流程|天宫_新闻资讯
央视网消息(记者 王小英 王甲铸)今晚22时04分，中国在酒泉卫星发射中心发射天宫二号空间实验室，承担发射任务的是长征二号F火箭。
据了解，长征二号F火箭分为两级，火箭起飞时，它的重量接近500吨，其中90%都是液体燃料的重量。一级火箭、二级火箭以及火箭上捆绑的四个助推器如同六个巨型燃料箱，装满燃料为火箭提供强大的动力。为了让火箭轻装前行，六个燃料箱在燃料用完以后都会被扔掉。
长征二号F火箭将天宫二号送入预定轨道，整个过程大约需要585秒左右。不到十分钟的时间里，“天宫二号”将与长征二号F火箭上演一场飞天大片，火箭各部段先后完成自己的使命，依次分离，最后将天宫二号送入太空。
航天科技集团一院长征二号F火箭总设计师荆木春向媒体解密了火箭发射天宫的全流程。
起飞后12秒，火箭将不再垂直向上飞行，而是拐一个弯，要沿着地球的倾斜度来飞行，来节省火箭的燃料，这一动作叫做程序转弯。转弯以后，将基本沿着平行地球轨道的方向飞行。
飞行到155秒，火箭四个助推器燃料耗尽，与火箭主体脱离。
160秒，一级火箭燃料耗尽，一二级火箭分离，火箭二级发动机启动。
210秒，二级火箭带着天宫飞出大气层，保护航天器的顶部整流罩也结束了自己的使命，同样也要被火箭抛掉。582秒，火箭二级发动机在燃料用尽后停止工作。三秒以后，船箭分离，火箭将天宫送到预定轨道，火箭的使命至此结束。
作为中国载人航天工程的“功勋火箭”，自1999年至2013年，11枚长征二号F火箭“接力”升空，成功发射“神舟一号”至“神舟十号”飞船和“天宫一号”目标飞行器，将10位航天员送入太空，成功率百分之百，圆了中华民族千年的“飞天梦”。
