播音员:SpaceX的星舰9号任务旨在解决先前任务中出现的问题,特别是星舰8号任务中发生的甲烷泄漏和发动机爆炸问题。为了避免类似的灾难,SpaceX对星舰进行了多项改进,包括增强甲烷管道和更新隔热瓦片。然而,这些改进能否完全解决问题,并确保星舰9号成功进入轨道,仍存在不确定性。 此次任务将使用新的星舰原型机Ship 35和助推器16号。Ship 35属于Block 2系列,具有更轻的重量和更高的性能,但同时也可能存在新的设计缺陷。SpaceX正在积极探索解决方案,例如加强甲烷输送管线,增加减震器,或调整发动机启动程序。修复的范围将决定是否需要对Ship 35和36进行改造,或者直接使用Ship 37。 除了解决燃料管道问题,SpaceX还在星舰9号上进行了其他改进,例如增强结构的卡销连接点,这将有助于未来的回收尝试。此外,SpaceX还在对隔热罩进行改进,以提高耐用性和减轻重量。 星舰9号的任务目标与之前的任务类似,包括测试整个系统的性能,并尝试实现首次完全成功的端到端飞行。这包括超级重型助推器的点火和推进、星舰与助推器的分离、助推器的翻转机动和回收、星舰的轨道速度轨迹、再入大气层以及最终的着陆。 SpaceX希望星舰9号能够成功进入近地轨道或至少达到接近轨道的速度,并安全地再入大气层。此外,星舰9号还将携带和部署测试有效载荷,例如星链卫星模拟器,以测试部署机制。SpaceX还将收集有关星舰空气动力学和隔热罩性能的数据。 星舰9号的发射时间取决于问题的解决和FAA的安全审查。虽然SpaceX的目标是尽快发射,但由于之前的失败,他们可能会采取更谨慎的态度,确保任务的成功。如果星舰9号成功,SpaceX可能会加快后续任务的节奏。

Deep Dive

Chapters
SpaceX's Starship Flight 8 ended prematurely due to an apparent Raptor vacuum engine explosion. Investigations suggest that the methane propellant feed lines might be vibrating at a damaging frequency as the fuel tank empties, leading to cracks or leaks that cause engine fires. The Block II design changes may have inadvertently introduced a fuel plumbing issue.
  • Raptor vacuum engine explosion on Flight 8
  • Methane propellant feed line vibration leading to cracks or leaks
  • Block II design changes potentially introduced fuel plumbing issue

Shownotes Transcript

SpaceX’s Starship Flight 9 claims to solve the feed-line resonance that doomed its predecessor, Starship Flight 8 — and are reinforced methane ducts and updated TPS tiles enough to avert another metal-shower inferno?Will these engineering upgrades finally achieve orbit, or will a Raptor re-ignition expose an even deeper design flaw?
