马斯克 的最新消息
@PPathole @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Some small tubes & wiring need to be nested in a bigger tube for thermal protection, kinda like conduit in a house.
Engines themselves & booster base are extremely robust. High strength stainless steel is bulletproof to a handgun at ~2.5mm thickness. Booster dome is 4mm.
@PPathole@Erdayastronaut@SpaceX@Caspar_Stanley@IzanRamos2002一些小管子和;布线需要嵌套在一个更大的管中进行热保护,有点像房子里的导管。
发动机本身;助推器底座非常坚固。高强度不锈钢在2.5mm厚的手枪上是防弹的。增压器圆顶为4mm。
@DJSnM @Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Electric power for booster & ship is needed even when engines aren’t running & incremental power draw of TVC isn’t too bad. We have local supercaps on each engine to deal with power spikes.
@DJSnM@Erdayastronaut@SpaceX@Caspar_Stanley@IzanRamos2002助推器电力;即使发动机不运转,也需要船舶;TVC的增量功率消耗并不太糟糕。我们在每个引擎上都有本地超级地图来处理功率峰值。
@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 Enabling engines to take the heat without shrouds might save over 10 tons, all things considered.
Shrouds are also a risk in that fuel leaks could be contained by the shroud, forming a MOX bomb.
Booster is purging all 33 engine shrouds in flight to prevent this.
@Erdayastronaut@SpaceX@Caspar_Stanley@IzanRamos2002使发动机能够在没有护罩的情况下吸收热量,从各方面考虑,可能节省10吨以上。
护罩也有风险,因为燃油泄漏可能被护罩控制,形成MOX炸弹。
助推器正在清除飞行中的所有33个发动机护罩,以防止出现这种情况。
@Erdayastronaut @SpaceX @Caspar_Stanley @IzanRamos2002 All mass necessitated by an engine design should count as engine mass, eg shrouds, TVC hydraulic power or excess purge gas.
Raptors in production now have electric TVC, saving over a ton of hydraulics mass on booster.
@Erdayastronaut@SpaceX@Caspar_Stanley@IzanRamos2002发动机设计所需的所有质量应计为发动机质量,例如护罩、TVC液压动力或过量净化气体。
生产中的猛禽现在有电动TVC,在助推器上节省了超过一吨的液压质量。

@arctechinc 10.13 goes to internal beta tomorrow, external next week. Should handle Chuck’s complex left turn.
Beta v11 hopefully end of next month, which just amounts to incorporating highway. Importance of “v11” has been reduced by all the 10.x releases. We’re already mostly at v11.
@arctechinc 10.13将于明天进行内部测试,下周进行外部测试。应该能应付Chuck复杂的左转。
Beta v11有望在下个月底发布,这相当于整合了高速公路。“v11”的重要性降低了所有10个。x版本。我们已经基本上在v11了。
