1941: the best radial engine

[tomo pauk]

Some good reading about the Soviet M-82 and M-71 radials, in 1941 they are available only in experimental form.

The translation is not that accurate, but you'll get the picture.

For knowledgeable people: was the Hercules ever considered with two-stage supercharger, ie. was it ever even a paper project in that guise?

[Shortround6]

There were 2-3 Vickers Wellingtons MK Vs with either two stage or turbocharged Hercules engines. They were counter parts to the MK VI with the Merlin 60s. How much they were flown and what their actual performance or problems were seems to bey mown or little reported.
Bristol had used a two stage Pegasus to set a world altitudes record in 1938?
