长七A火箭测发周期再缩6天 为高密度发射提前准备_测试_工作_我的网站
A | A Russian governor was accused by critics on Sunday of “discrediting Russia’s armed forces” after telling residents in her region that the country had “no need” for its war in Ukraine.Natalya Komarova, the governor of the Khanty-Mansiysk region and a member of President Vladimir Putin’s governing United Russia party, made the remarks during a meeting with residents in the Siberian city of Nizhnevartovsk on Saturday.Critics have called for authorities to launch an investigation into her remarks, but Komarova hasn't been detained or faced any charges so far.A video of the event posted on social media showed the politician being confronted by the wife of a Russian soldier who said that mobilized men had been poorly equipped for the front line.Komarova told residents that Russia hadn't been prepared for the invasion of Ukraine.“Are you asking me (why your husband does not have equipment), knowing that I’m the governor and not the minister of defense?”, the 67-year-old said.“As a whole, we did not prepare for this war. We don’t need it. We were building a completely different world, so in this regard, there will certainly be some inconsistencies and unresolved issues,” she said.Komarova’s comments quickly spread online, reportedly prompting pro-war activists to denounce the politician to authorities for “discrediting Russia’s armed forces.”News outlet Sibir.Realii reported that its journalists had seen a letter from the director of a Siberian non-profit organization, Yuri Ryabtsev, to Russia’s Minister of Internal Affairs, calling for a further investigation of Komarova’s comments.Days after Putin sent troops into Ukraine on Feb. 24, 2022, Russia’s Kremlin-controlled parliament approved legislation that outlawed disparaging the military and the spread of “false information” about Moscow’s invasion of Ukraine.Russian courts have used the legislation to hand out fines and prison terms to opposition critics, including those who describe Moscow’s full-invasion of Ukraine as a war, instead of using the Kremlin’s preferred euphemism of “special military operation.”。

C | “现在，我们先吊装好助推器和一二级，在等待芯三级的过程中，插空进行助推器和芯二级的伺服机构安装工作，等三级具备条件，再进行吊装。再加上仪器设备上箭安装等分系统测试前准备工作优化了1天，算下来，本阶段比以往的模式可以节省3天时间。”魏远明说。合并“同类项” 抢出2天测试时间总装及单元测试后，火箭需要进行分系统匹配测试和总检查测试，验证其技术性能和可靠性，使其达到符合发射状态的要求。在这次任务中，团队将具备类似状态的测试进行了一次合并“同类项”，进一步缩短检测时间。增补压测试是分系统动力系统测试的最后一项测试，紧接着就是进行第一次总检查测试。总检查测试和增补压测试都会运行模飞程序。研究团队提出，“如果两者合并，是否可以减少总检查测试的一部分工作？合并后能否达到相同测试效果？”经过研究分析，团队找出两个测试存在的差别，在增补压测试中加强了对测量系统的验证，让测试更全面，实现用更少的时间达到相同测试效果。

E | 串行变并行 转场及发射区工作省下1天时间转场当天，长七A火箭“站”在活动发射平台上，缓缓“走”向发射塔架。这意味着火箭在技术准备区经检查测试达到了可以进行发射的状态。在以往发射中，长七A火箭从转场加上在发射区的工作，一共需要4天时间。这次团队梳理流程，将测量系统的恢复和测试工作由串行改为并行，使转场与发射区工作缩减为3天，这是目前发射区占位时间最短的液体火箭。9月13日，长征七号A遥五运载火箭在文昌航天发射场成功发射中星1E卫星。
