How much speed of the slow mo?

Always cool to see

Beautiful!

Raptor shutting down in slowmo is like physics flexing in real time—shout out to whoever thought to film it this way. Absolute art.

this video was a while ago, but nice pulsations

It's from the 11th of april 2024 to be precise

Mesmerizing to watch! Thanks for sharing!

That resonance can’t be good for the components if these engines are expected to last for hundreds of flights.

Combustion-acoustic coupling: Heat release from combustion synchronizes with acoustic modes (longitudinal, tangential, or radial) in the chamber, reinforcing pressure waves. Injector dynamics: Non-uniform propellant mixing or injection can create localized combustion zones, triggering instabilities.

Shutdown of a Raptor vacuum engine in slow motion. The engine’s nozzle is sized for use by Starship in the Earth’s upper atmosphere and outer space, so operation at sea level and low chamber pressures results in flow separation creating visible rings in the exhaust

Elon Musk: Raptor 3 is alien technology. “Raptor 3 is a massive increase in payload capability, in engine efficiency, and in reliability. This is really a revolutionary engine. Raptor 3 is really kind of an alien technology rocket engine. Even industry experts, when we showed a picture of the Raptor 3, said, that engine is not complete. Then we said, here's the engine, not complete, firing at a level of efficiency that has never been achieved before. That is one clean engine. In order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself so everything is contained and protected. It is a marvel of engineering, frankly.” From: SpaceX Update, May 27, 2025

Elon Musk on Raptor 3 Engine: "Raptor 3 is designed to require no basic heat shield, saving a lot of mass on the bottom and actually improving reliability, so that if there is, for example, a small fuel leak from the Raptor engine, it will simply leak into the existing flaming plasma and not really matter, whereas a fuel leak when the engines are contained in a box is a very scary thing indeed. It will be a massive increase in payload capability, in engine efficiency and in reliability. So this is really a revolutionary engine. Raptor 3 is really, I'd say, kind of alien technology, rocket engine. So in order to make the engine like that, we had to simplify so many parts of the design, incorporate secondary fluid circuits and electronics in the structure of the engine itself, so everything is contained and protected. It is a marvel of engineering."

Elon Musk: Raptor 3 is kind of alien technology “Even industry experts, when we showed a picture of the Raptor 3, said, ‘That engine is not complete’” “Well, here’s the engine - not complete - firing at a level of efficiency that has never been achieved before” Raptor 3 is a massive leap forward in rocket engine design • No base heat shield required, saving huge mass and improving reliability • Fuel leaks are no longer catastrophic, they safely burn off in open plasma • Dramatically higher payload capacity and efficiency • Simpler design with fewer parts, but far more capability • Secondary fluid systems and electronics are integrated directly into the engine structure
