Long seventh restored rocket launch just around the corner, three dimensional animation combined transport process
Marquee long seventh rocket planned for June 25 to 29th time launch, it will be presented the rocket for the first time. Bears "for up to seven" and carrying the load combination of active launch platform, after the 22nd, at 8 o'clock after about 3 hours of steady driving, safe transfer to the launching Tower, marks the official launch of the rocket stage.
Long seventh restored rocket launch just around the corner, three dimensional animation combined transport process
Marquee long seventh rocket planned for June 25 to 29th time launch, it will be presented the rocket for the first time. Bears "for up to seven" and carrying the load combination of active launch platform, after the 22nd, at 8 o'clock after about 3 hours of steady driving, safe transfer to the launching Tower, marks the official launch of the rocket stage.
"Up to seven" adoption of the new three-down "test pattern, shorten the preparation time before the shooting, improving the reliability of launch.
"Up to seven" arrow to connect to only one docking has become, the lower probability of failure.
"Up to seven" campaign launch platform in the transition process to turn 4 60-degree turn, achieve the Chinese launch vehicle activities launch platform turns walking "zero".
Active launch platform, 26 meters wide and 23 meters long and weighing 1800 tonnes, is the most difficult to break through the "monorail differential turn walking technology".
Turning running gear for a rockets team learn from the port, and had a lot of simulation and testing.
China became the 2nd master "Mono differential turn walking technology" country, following the United States, the European Space Council, Japan 4th master "launch platform turns travel technology" of the country.
"Up to seven" only a front test and control equipment, installed inside the activity the launch platform. After streamlining the rocket vertical transitions, the launch complex for gas, liquid and docking as well as the test again.

长征七号发射在即 三维动画还原火箭合体转运全程
长征七号发射在即 三维动画还原火箭合体转运全过程
　　字幕长征七号运载火箭计划于6月25日至29日择机发射，这将是该型火箭首次正式亮相。承载着“长七”与搭载载荷组合体的活动发射平台，22日8点经过约3小时平稳行驶后，安全转运至发射塔架，标志着火箭正式进入发射阶段。

　　字幕长征七号运载火箭计划于6月25日至29日择机发射，这将是该型火箭首次正式亮相。承载着“长七”与搭载载荷组合体的活动发射平台，22日8点经过约3小时平稳行驶后，安全转运至发射塔架，标志着火箭正式进入发射阶段。
　　“长七”采用“新三垂”测发模式，缩短了射前准备时间，提高了发射可靠性。
　　“长七”的箭地连接工作仅一次对接就成，出现故障的概率更低。
　　“长七”活动发射平台在转场过程中要拐4个60度的弯，实现了中国运载火箭活动发射平台转弯行走“零”突破。
　　活动发射平台，长26米、宽23米、重1800吨，最难突破的是“单轨差速转弯行走技术”。
　　火箭研究团队借鉴港口应用的转弯行走装置，并进行了大量的仿真计算和试验。
　　中国成为第2个掌握“单轨差速转弯行走技术”的国家，也是继美国、欧空局、日本之后第4个掌握“发射平台转弯行走技术”的国家。
　　“长七”仅有一套前端测发控设备，安装在活动发射平台内。精简了火箭垂直转场后，在发射区进行的气、液、电再次对接以及相应的测试工作。
