星舰 V3 | 第 12 次试飞

12th test flight of the two-stage Starship launch vehicle. Maiden Flight of Starship V3. The flight test’s primary goal will be to demonstrate each of these new pieces in the flight environment for the first time, with each element of the Starship architecture featuring significant redesigns to enable full and rapid reuse that incorporate learnings from years of development and test. The Starship upper stage will target multiple in-space and reentry objectives, including a payload deployment of 20 Starlink simulators, similar in size to next-generation Starlink V3 satellites, and two specially modified Starlink satellites. The two modified satellites will test hardware planned for Starlink V3 and will attempt to scan Starship’s heat shield and transmit imagery down to operators to test methods of analyzing Starship’s heat shield readiness for return to launch site on future missions. Several tiles on Starship have been painted white to simulate missing tiles and serve as imaging targets in the test. The Starlink simulators will be on the same suborbital trajectory as Starship. A relight of a single Raptor engine while in space is also planned. For Starship entry, a single heat shield tile has been intentionally removed to measure the aerodynamic load differences on adjacent tiles when there is a tile missing. Finally, the ship will perform experimental actions tested on previous flight tests, including a maneuver to intentionally stress the structural limits of the vehicle’s rear flaps and a dynamic banking maneuver to mimic the trajectory that future missions returning to Starbase will fly.

两级星舰运载火箭的第 12 次试飞，也是星舰 V3 的首飞。 本次飞行试验的主要目标将是在飞行环境中首次演示这些新部件，星舰架构的每个组成部分都进行了重大重新设计，以实现全面、快速的重复使用，并融入多年开发与测试的积累。 星舰上面级将瞄准多项在轨与再入目标，包括部署 20 颗星链模拟卫星（尺寸与下一代星链 V3 卫星相近）以及两颗经过特殊改装的星链卫星。这两颗改装卫星将测试为星链 V3 规划的硬件，并试图扫描星舰的热防护罩并将图像下传至操作团队，以测试分析星舰热防护罩是否具备未来任务返回发射场条件的方法。星舰上的若干隔热瓦被涂成白色，以模拟缺失的瓦片并作为测试中的成像目标。星链模拟卫星将与星舰处于相同的亚轨道轨迹。还计划在太空中重新点火单台猛禽发动机。 在星舰再入时，有意移除了一块热防护罩瓦片，以测量瓦片缺失时相邻瓦片所受气动载荷的差异。最后，飞船将执行此前飞行试验中验证过的实验性动作，包括有意施压飞船后襟翼结构极限的机动，以及模拟未来返回 Starbase 的任务所飞轨迹的动态倾斜机动。
