Since this year, China ’s aerospace launch has suffered two defeats, but today, China has achieved the first successful mission of the Long March 5B carrier rocket and fought a beautiful “turn over battle”. At the press conference for the first flight mission of the Long March 5B carrier rocket held on the evening of May 5, Ji Qiming, assistant director of the China Manned Space Engineering Office, responded: On March 16 and April 9 of this year, China ’s space launches were two consecutive The loss also shows the high risk of the aerospace industry. For more than a month, the model team and the aerospace experts have been working together, night and day, concentrated battles, in-depth development of problem review, cause analysis, test verification and other zero work. The fault location and mechanism are basically clear. At the same time, the relevant departments organized a comprehensive quality rectification and review review across the entire spaceflight, and made appropriate adjustments to the rocket launch plan originally scheduled to be implemented in the near future.
He said that as one of the most complex aerospace projects with the highest safety requirements, manned aerospace always adheres to quality first and safety first. The Long March 5B carrier rocket is responsible for the important mission of launching the cabin section of the space station. It is related to the realization of the “three-step” strategic goal of the manned spaceflight project, and it cannot tolerate any failure. On the basis of a large amount of quality safety and reliability work carried out in the early stage, in response to the two recent launch failures, the Long March 5B carrier rocket and mission-related systems immediately carried out fault stripping and inferences, and re-checked the technical status and product quality. Review and confirm again, comprehensively investigate risks and weak links, further improve the plan, and strive to turn the lessons of failure into valuable wealth.
The successful launch of the Long March 5B carrier rocket not only achieved the first battle of the space station phase mission, but also fought a “turn over battle” for China Aerospace for the follow-up The task adds greater confidence.
