Blue Origin narrowing in on root cause of catastrophic rocket accident
摘要
Blue Origin正就今年5月其“新格伦”火箭在佛罗里达州卡纳维拉尔角发射台热试车中发生的灾难性事故展开调查。公司CEO戴夫·林普首次证实，问题源于火箭一级七台BE-4发动机中一台的主氧气阀，该结论已通过硬件回收与检查确认。目前，公司正进行部件级与发动机热试车测试，以深入理解故障模式并制定应对措施。
Blue Origin provided its first substantive update this week on the cause of the catastrophic loss of the New Glenn rocket and most of its launch pad infrastructure at Cape Canaveral, Florida, in May.
The space company's chief executive, Dave Limp, said investigative work is continuing into the anomaly that happened during a hot-fire test of the rocket during the evening of May 28, 2026. He confirmed, for the first time, widespread speculation that the problem started in one of the rocket's seven BE-4 engines that power the vehicle's first stage.
"The anomaly originated at the main oxygen valve on one of the BE-4 engines, which was later confirmed by hardware recovery and inspections," he said. "Extensive component-level and engine hotfire tests have been conducted to understand the failure mode better and inform mitigations."
