Here is a not-dissimilar American ejection system that was fitted to a Sikorsky research heli. Never adopted for actual production helicopters, but it’s the same idea as the one in the Kamov 50/52.

That system is so “not-dissimilar” that it makes me wonder where the Russian designer may have gotten the basic sequence idea.

That is -very- similar.

Thanks, Sptyr.
