Four earlier shenzhou spacecraft have already made orbital flights , but unlike those unmanned test vehicles , shenzhou 5 is expected to carry a crew of up to three young chinese military pilots 先前已经有四具神舟号完成轨道飞行，但五号与这些无人测试载具不同，它将会负载多达三名的年轻中国军机飞行员。
Yang has spent 21 hours in outer space , traveling more than 600 , 000 kilometres in the earth ' s orbit before shenzhou 5 brought him back at 6 : 07 am beijing time october 16 . yang said he feels excellent after the 21 - hour journey , the first by a chinese 北京时间10月16日早晨6点零7分，在太空遨游二十一小时绕地球轨道飞行60多万千米的中国航天员杨利伟，乘坐“神舟”五号航天飞船顺利归来。
Webber said a surprising 7 percent of the wealthy polled said they would be willing to take a two - week flight to an orbiting space station , paying the million that the russians charged the two pioneering space tourists who have already made the trip , south african mark shuttleworth and american dennis tito 韦伯说，他非常惊讶，竟然有7 %的有钱人愿意象南非富翁马克?沙特尔沃斯和美国富翁丹尼斯?蒂托一样，花2千万美元沿着轨道飞行一周。
According to purpose of the towed flight , a new trajectory consisting of taking off , climbing phase , level flight phase is presented with . trajectory pitch angle of the towing plane is optimized . according to the flight law of the towing plane , the fin deflection angle and amplification coefficient of particle - system trajectory of carrier rocket are designed , in order to realizing flight steadily of the carrier rocker 根据牵引飞行的目的，对载机应用了“起飞?爬升?平飞”的变轨道飞行方案，同时对载机轨道的倾角、倾角变化规律进行优选设计；再根据载机的飞行规律，对运载器质点系轨道的舵偏规律及其放大系数进行了设计计算，实现运载器稳定牵引飞行。
