tater Posted July 11, 2022 Share Posted July 11, 2022 Fire is between OLS and tank farm berm. Could be any number of things. Black smoke... perhaps a vehicle (small crane, etc) with wheels, and rubber burning? Quote Link to comment Share on other sites More sharing options...

RCgothic Posted July 11, 2022 Share Posted July 11, 2022 Nope. Looks like a fuel-air detonation. I'd be surprised if all 33 raptor 2s came out of that intact. Quote Link to comment Share on other sites More sharing options...

sevenperforce Posted July 12, 2022 Share Posted July 12, 2022 (edited) If there was a fuel-air detonation, it was a very small one. There was no visible shockwave, which is what you would expect to see from a proper stoichometric fuel-air detonation. My guess is a small fuel-air detonation near the vehicle followed by conflagration of fuel-rich preburner exhaust. If there was damage to the vehicle it would have been from the initial small detonation; the conflagration should be less of an issue. Delta IV Heavy lights itself on fire at launch, after all; I can't imagine a little gout of fire is any more dangerous of a regime to the booster than the expected re-entry conditions. The fire probably damaged GSE, though. My guess is that they'll need to replace a half-dozen engines and a few dozen GSE parts. I don't know why they would be running the fuel preburners without an overpressure notice. That seems dumb.

However, South Texas... So yep. 28 minutes ago, sevenperforce said: don't know why they would be running the fuel preburners without an overpressure notice. That seems dumb And possibly AnothER delay if FAA / EPA thinks that they should have issued a notice, but did not. Edit - one good thing about SX and the access we have; the KSP2 artists have lots of images of how rockets go boom.

Ultimate Steve Posted July 12, 2022 Share Posted July 12, 2022 (edited) Tweet contains profanity, so I won't post it directly but there is something in this video that looks at least somewhat shockwave-like: [snip] Volume warning.

You can see stuff lift off the arms. There's also damage to some of the lighter structures near the top. I don't think its major structural - but the moving parts and attendant gear look messed up.

Can't tell what it is... but they're likely not getting close tonight.

So it does look like there was definitely a detonation wave. That being said, the massive gout of fire that followed suggests only a very minimal amount of fuel actually was involved in the detwave so hopefully that's a good sign.

That seems right, it sounds like the Raptor spin up required CH4 and that went in a place where it shouldn't meeting some LOX. Rapid Unscheduled Static Fire?

CatastrophicFailure Posted July 12, 2022 Share Posted July 12, 2022 Few days late, but… oh, say, can you see, by the dawn’s early light? Something something bomb bursting in… ground… Actually this is probably a good thing, been too long since they had a flaming hiccup. Quote Link to comment Share on other sites More sharing options...
Beccab Posted July 12, 2022 Share Posted July 12, 2022 Another theory I've seen on the anomaly: independently from the cause of the main detonation, the second fire with black smoke that started a bit later came from a generator on the ground - LOX reached its intake, increasing the speed of the combustion and overheating to the point of burning down. How does it sound? Quote Link to comment Share on other sites More sharing options...

How does it sound? Wouldn't even need to be LOX. An increase in GOX concentration could also cause an overspeed. Quote Link to comment Share on other sites More sharing options...
