Someone posted a meme of the raptor engine evolution with each version being a more simplified and streamlined. The fourth version was a toilet plunger.
I always think of it when new versions of the engine are shown. |

The amount of work required to simplify the Raptor engine, internalize secondary flow paths and add regenerative cooling for exposed components was staggering. As a result Raptor 3 doesn’t require any heat shield, eliminating heat shield mass & complexity, as well as the fire suppression system. It is also lighter, has more thrust and has higher efficiency than Raptor 2. Truly, a work of art. |

Important to note that the induced mass (mass required by a given engine design that is not the engine itself) of Raptor 3, while far better than Raptor 2, still has a lot of room for improvement. Thrust will exceed 300 tons with Raptor 3.x (thrust/mass>200), enabling 10,000 tons of thrust at liftoff and there might be up to 5 sec of Isp gain over time. Getting close to the limit of known physics.

Yep, so many advances by Space X just leaving everyone else in the dust! They're an incredible team!
It's no wonder why everyone with a vested interest in old space, and the newer programs that simply can't keep up, are trying every underhanded trick under the sun to stop them. |

Quote HistoryOriginally Posted By Hesperus: Elon really does like to push things to the absolute limits. I remember some years ago hearing Eric Weinstein saying that we should be working on gravity drives instead of better rocket engines. Maybe a gravity drive would be easier than this? Sure, just bet everything on pulling a bunch of completely new branch of physics out of a hat on demand. If we eventually get gravitics and FTL, that will be amazing. But to put everything else on hold until having them is beyond stupid. Especially since by definition we don't know if some key insight can only come after we've spread off world, let alone if they are possible. |
