Raptors are state of the art. They are based on a soviet design from the 60s in the same way that they are based on US designs from the 60s.
It's weird that people seem so keen to talk up the soviet part and talk down the US part.
- cnlevy 6y agoI think he is referring to the Soviet https://en.wikipedia.org/wiki/RD-270 https://en.wikipedia.org/wiki/RD-270 full-flow staged combustion engine from the 60s. The Americans had not been able to preserve the high-pressure hot oxygen from eating the preburner.
- jjoonathan 6y agoYes, the soviets had great accomplishments with the oxygen-rich cycle, but they had coking problems in the fuel-rich cycle that the US overcame -- there's a reason why it took until the Raptor for FFSC to become commonplace. I don't mind acknowledging the great soviet accomplishments, of which there are many, but the circlejerk tendency to inflate their accomplishments and shrink their shortcomings (while doing the opposite to Cold War US) is insanely strong. It makes me wonder if I'm speaking to bots!
