It's clear that with SpaceX, Elon Musk wants to push the boundaries of space travel, even if every project isn't a success. Despite scrapping 100 Starlink satellites, there are plenty of important missions SpaceX has completed, and the spacecraft manufacturer has been focusing on a new behemoth: Starship. 

显然，埃隆·马斯克希望通过 SpaceX 突破太空旅行的界限，即使并非每个项目都取得成功。尽管废弃了 100 颗 Starlink 卫星，但 SpaceX 已经完成了大量重要任务，这家航天器制造商一直专注于一个新的庞然大物：星际飞船。

Starship is the largest rocket ever flown. It measures 397 feet tall, weighs hundreds of thousands of pounds, and is made of stainless steel. Naturally, with all that mass, it's going to take an impressive amount of thrust for the spacecraft to not only take off but generate enough velocity to exit Earth's atmosphere. That's where SpaceX's Raptor engines come into play. In total, the Starship Heavy has 39 Raptor engines, with most of them located on the Super Heavy. 

星舰是有史以来飞行过的最大的火箭。它高 397 英尺，重数十万磅，由不锈钢制成。当然，凭借如此大的质量，航天器不仅需要巨大的推力才能起飞，而且要产生足够的速度才能离开地球大气层。这就是 SpaceX 的 Raptor 发动机发挥作用的地方。重型星舰总共拥有 39 个猛禽发动机，其中大部分位于超重型舰上。

The Super Heavy is the Starship's booster, the first stage of the spacecraft's launch system that eventually separates once it reaches Earth's orbit. The reusable booster features 33 Raptor engines powered by liquid methane (CH4) and liquid oxygen. All are found on the spacecraft's tail end (bottom), with 13 in the center while the remaining 20 encircle them, working together to create behemoth thrust when ignited. 

超级重型火箭是星舰的助推器，是航天器发射系统的第一级，一旦到达地球轨道，它最终会分离。可重复使用的助推器配备 33 个由液态甲烷 (CH4) 和液态氧提供动力的猛禽发动机。所有这些都位于航天器的尾端（底部），其中 13 个位于中心，其余 20 个环绕它们，在点燃时共同产生巨大的推力。

Six Raptor engines power the main Starship craft once the Super Heavy breaks off after the initial launch. Three are traditional Raptor engines, while the other three are Raptor Vacuum engines designed for use in the vacuum of space.

一旦超重型飞船在首次发射后中断，六台猛禽发动机将为主星舰飞船提供动力。其中三个是传统的猛禽发动机，另外三个是专为真空太空设计的猛禽真空发动机。

How powerful are SpaceX Raptor engines?

SpaceX 猛禽发动机有多强大？

It's hard to imagine the amount of thrust needed to launch a space shuttle into orbit, let alone one as massive as SpaceX's Starship. However, the company's Raptor engines do just the trick, even if they need nearly 40 of them to complete the spacecraft's journey. So, how powerful are they?

很难想象将航天飞机送入轨道需要多大的推力，更不用说像 SpaceX 的星际飞船那么大了。然而，该公司的 Raptor 发动机却能起到作用，即使他们需要近 40 个发动机才能完成飞船的旅程。那么，他们的实力到底有多强呢？

Each Raptor engine has a thrust of 230 ton-force (tf) or 507 kip-force (klbf). Considering the Super Heavy has 33 total engines, that means it's outputting 7,590 ton-force to get the Starship (plus the booster) off the ground and into space. For comparison, the GEnx-2B Engine that powers a Boeing 747-8 creates 66,500 lb of thrust compared to the 507,063 pound-force from each Raptor engine. 

每个 Raptor 发动机的推力为 230 吨力 (tf) 或 507 kip 力 (klbf)。考虑到超重型总共有 33 个发动机，这意味着它可以输出 7,590 吨的力量来让星舰（加上助推器）离开地面进入太空。相比之下，为波音 747-8 提供动力的 GEnx-2B 发动机可产生 66,500 磅的推力，而每个猛禽发动机可产生 507,063 磅的推力。

However, the SpaceX propulsion team didn't stop there. In May 2023, Elon Musk tweeted that the SpaceX engineers achieved even more thrust with the Raptor V3. The newest version of the space rocket achieved 269 tons of thrust, putting the Super Heavy Booster's total thrust at 8,877 tons or 19.5 million pounds. 

然而，SpaceX 推进团队并没有就此止步。 2023 年 5 月，埃隆·马斯克 (Elon Musk) 在推特上表示，SpaceX 工程师利用 Raptor V3 实现了更大的推力。最新版本的太空火箭可实现 269 吨的推力，使超重型助推器的总推力达到 8,877 吨或 1950 万磅。

On the other hand, the Raptor Vacuum engines boast a larger exhaust and expansion nozzle, which increases their efficiency and possesses more thrust than the standard Raptors (especially in space). The engines output 258 tf, giving Starship 774 tons of force (from just three RVacs) after separation in space.

另一方面，猛禽真空发动机拥有更大的排气和膨胀喷嘴，这提高了效率并比标准猛禽拥有更大的推力（特别是在太空中）。发动机输出 258 tf，在太空分离后为星际飞船提供 774 吨的力量（仅来自三架 RVac）。
