The Raptor engine looks a lot like a Merlin, with one key difference—by significantly increasing the pressure, SpaceX has made the Raptor over three times more powerful than a Merlin. A single Raptor engine produces310 tonsof thrust—enough to lift 310 tons, or a stack of 172 cars, oran...
这个发动机，真是袖珍，却有55吨的推力……技术含量很高
将飞船推离助推器。太空探索技术公司用电子推力矢量控制取代了超重型猛禽发动机的液压系统，理由是潜在的故...
例如，SpaceX已经制造并测试了热级间分离系统（hot-stage separation system），在该系统中，“星舰”飞船的第二级发动机会点火将飞船推离助推器。此外，SpaceX还为“超重型”猛禽发动机（Raptor）设计了新的电子推力矢量控制（Thrust Vector Control，TVC）系统。与传统液压系统相比，新系统使用全电动马达，潜在故障点...
太空探索技术公司SpaceX在2016年开展行星际运输系统,后改名为Starship,在沉寂半年后,Elon Musk先前在Twitter上发文更新Starship计划情况,并预计在5月进行轨道飞行测试。 First Starship orbital flight will be with Raptor 2 engines, as they are much more capable & reliable. 230 ton or ~500k lb thrust at se...
pressure, Raptor has gained a significant amount of thrust: Raptor 1 produced 185 tonnes of thrust while Raptor 2 produces 230 tonnes of thrust. The downside, though, of opening the throat is a ~1% decrease in ISP: Raptor 1 hit roughly 330 seconds of ISP while Raptor 2 reaches 327 ...
2009年2月,这是本文的一个关键节点。SpaceX的Max Vozoff在美国航空航天研究所(AIAA)商业乘员/货运研讨会上第一次公开提到了SpaceX正在发展一款名叫”猛禽“(Raptor)的火箭发动机。(主角终于登场) 这是大家最后见到的”猛禽“,但是它最初并非这个样子,中间的故事很长 ...

The rocket was equipped with 33 Raptor engines, but SpaceX founder Elon Musk tweeted that engineers disabled one engine just before ignition and "1 stopped itself, so 31 engines fired overall." "But still enough engines to reach orbit!" he added. ...
Raptor 2 generates more than 230 tons of thrust at sea level, up from Raptor 1’s 185 tonspic.twitter.com/o1Rqjwx6Ql — SpaceX (@SpaceX)February 11, 2022 On Raptor 1, the preburners would ignite once a high enough flow rate was achieved, producing hot gas that the main combustion ...
