How many flights is the Merlin actually good for with no major refurbishment now that you’ve reflown it so many times? Is the bearing the limiting factor? Or is it the coking?
Elon Musk
@elonmusk · Jun 24, 2019
Merlin could probably do 1000 flights too. Turbine blade fatigue cracking would require periodic weld repair or replacement. Probably some seals & bearings as well. Coking not really an issue.

@elonmusk v2 significantly improved speed of enhanced summon, what does v3 bring? Better curb detection? Parking spot line detection?

~1000 flights with little maintenance?!? 🤯 What?! Seriously, what specifically about raptor makes it anywhere near capable of that compared to previous engines?! Something about the seals / bearings / materials / full flow producing max enthalpy?
Elon Musk
@elonmusk · Jun 24, 2019
Other rocket engines were designed for no (or almost no) reuse. Raptor is designed for heavy & immediate reuse, like an aircraft jet engine, with inspections required only after many flights, assuming instrumentation shows it good. Using hydrostatic bearings certainly helps.

Has the Starship increased it's re-usability. Your previous statements are that the booster would launch 1000 times but the starship only 100 (still impressive).

Planning on a simplifying mod to Raptor for max thrust, but no throttling, to get to 250 mT level

That’s kinda how I read that too 🤯 well, more than $200k, but still even if it’s less than $500k, that’s nuts!
Elon Musk
@elonmusk · Jun 24, 2019
Since Raptor produces 200 tons of force, cost per ton would be $1000. However, Raptor is designed for ~1000 flights with negligible maintenance, so cost per ton over time would actually be ~$1.

Cost wise, how much more expensive is Raptor than Merlin to produce? Twice as much? Three times-ish.... I estimated Raptor being around $2,000,000 but that was just a roughly educated guess.
Elon Musk
@elonmusk · Jun 24, 2019
More than that now, but <10% of that in volume, although much to be proven

~730 engines/year!! Wow!
Elon Musk
@elonmusk · Jun 24, 2019
Full year production is usually ~70% of peak daily rate, so 500/year. Still, non-trivial at 100,000 tons of thrust/year.

Any big changes happening between all the new serial numbers of Raptor? How's the testing coming along in Texas? Ready to stick another Raptor up in the hopper again any time soon?
Elon Musk
@elonmusk · Jun 24, 2019
Raptor liberated its oxygen turbine stator (appears to be mechanical, not metal combustion failure), so we need to update the design & replace some parts. Production is ramping exponentially, though. SN6 almost done. Aiming for an engine every 12 hours by end of year.
