@Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy All Raptors have slight throttle range by adjusting flow to ox & fuel turbines, but deep throttling imposes limitations on injector stiffness & needs extra hardware. Swear these are legit technical terms 🤗 — PolitiTweet.org

Elon Musk @elonmusk

@Some1gee @Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy It’s a factor. Main reason is that FFSC is the ultimate architecture for converting propellant into rocket velocity. — PolitiTweet.org

Elon Musk @elonmusk

@Elthiryel @Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy Yes, they run at *much* higher pressure, but lower temperature. Thermal shock & strain are what fatigue Merlin turbine blades. Solvable for high reusability, but better to apply that engineering to Raptor. — PolitiTweet.org

@SpaceXFan97 @Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy Same as last time, although we made a design improvement that could yield about 7 bar more — PolitiTweet.org

Elon Musk @elonmusk

@Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy 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. — PolitiTweet.org

@elontimes Yeah, we’ve been working on curbs a *lot*. Concrete seams too. So glamorous. — PolitiTweet.org

Elon Musk @elonmusk

@Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy 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. — PolitiTweet.org

Elon Musk @elonmusk

@Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy Planning on a simplifying mod to Raptor for max thrust, but no throttling, to get to 250 mT level — PolitiTweet.org

Elon Musk @elonmusk

@Erdayastronaut @13ericralph31 @HarryStoltz1 @flcnhvy 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. — PolitiTweet.org

@Erdayastronaut @HarryStoltz1 @flcnhvy More than that now, but <10% of that in volume, although much to be proven — PolitiTweet.org

Elon Musk @elonmusk

@HarryStoltz1 @Erdayastronaut @flcnhvy Full year production is usually ~70% of peak daily rate, so 500/year. Still, non-trivial at 100,000 tons of thrust/year. — PolitiTweet.org

Elon Musk @elonmusk

@Erdayastronaut @flcnhvy 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. — PolitiTweet.org
