But the diagram in the infobox appears to me to be a non-compound, turbo charged engine.
Andy Dingley, I see you're active, and you've been a good source of information on this sort of distinction in the past (I admit it), any comments?

So what's the issue? The turbo compounding is similar to (possibly copied from) the
Wright R-3350, with three power-recovery turbines mounted near the banks. Like the R-3350, there's also a mechanical supercharger at the rear of the crankcase. The difference is that there's an additional separately-mounted
turbosupercharger (like several of the
R-1820 models). Bigger and more complex than the comparable US radials, but not out of line as a post-war evolution to produce an intercontinental bomber. This engine was only ever intended for the
Tu-85.

Thanks, and you seem to be right, in that there's a label on the PRT cooling air. And there's an intercooler (unlabelled). So I guess the PRTs are there, just not shown in the diagram.
