近日,长征五号运载火箭在天津圆满完成了所有部段的进塔工作。至此,中国新一代大型运载火箭首次向世人展示其全貌。目前,该型火箭全面进入全箭模态试验阶段。长征五号运载火箭芯二级氢箱运抵低温区贮箱台后,进行了液氢工况内压合格试验、液氢轴弯内联合使用载荷合格试验以及整箱内压破坏试验等各项研制任务。该试验安全风险高、技术状态多、准备周期长。因此,试验过程中将工作重点放在试验风险识别处置、技术状态管控、计划动态监控协调等方面,以确保任务顺利完成。
Recently, the Long March V carrier rocket successfully completed all sections of the tower in Tianjin. At this point, China’s new generation of large carrier rocket shows the world for the first time. At present, this type of rocket fully enter the modal test mode. Long March V carrier rocket core second-level hydrogen tank arrived at the cryogenic tank station, the liquid hydrogen pressure conditions of qualified tests, the combined use of liquid hydrogen axial bending load test and the pressure inside the FCL test Development task. This test has high safety risk, many technical conditions and long preparation period. Therefore, in the course of the trial, the work will be focused on the identification of experimental risks, the control of technical conditions, and the coordination of planned dynamic monitoring so as to ensure the successful completion of the tasks.
