Nov 29, 2023 at 17:39 comment added Ian Kemp @MWB Both men were victims of Stalin's idiotic purges. To save his own skin Glushko was forced to make false charges against Korolev, who ended up in the Gulag as a result. Arguably, the deprivations Korolev suffered there eventually necessitated the 1966 surgery that killed him. Such a tragic waste of such a brilliant mind.
Nov 29, 2023 at 10:55 comment added Ian Kemp @Mark Glushko's biggest engine wasn't starting from scratch like the NK-15, though. The time it took Kuznetsov to design his engine from scratch is time that could have instead been used to integration test Glushko's engines.
Nov 29, 2023 at 5:26 comment added Mark It's not clear that the Korolev-Glushko disagreement was as important as it sounds. In 1963, when the decision to go with Kuznetsov was made, Glushko's biggest engine was comparable to the NK-15. It took Glushko seven years to develop the RD-270 as a counterpart to the F-1 -- solving combustion instabilities in a large engine is at least as hard as getting the plumbing right for a massive engine cluster. The big issue with the NK-15 was a lack of testing (and lack of resources for testing).
