Thank you to Ucon for posting very interesting information on those Beriev projects.
May I ask if "Princessa" was REALLY its name? It doesn't sound too much like a name a Soviet general constructor would elect to use in 1949 USSR...
As regards the next post :
"Do you have any more information on the 'Princess'?; was it a 'copy', or a planned conversion of the three built, assuming MoD would have sold them anyway? If the latter case the project would have been early 60s?, as they were scrapped in 1966" :
As dire as the economic situation of the UK might have been in the early sixties, believing that they might have sold the Saro Princess relics to the USSR sounds a little far-fetched, doesn't it? Wasn't there something known as the cold war going on at that time? (OK, there is the famous Rolls Royce's Nene and Derwent deal with the USSR as a precedent, but perhaps they wouldn't have made the same mistake twice?).
More generally, it is not very helpful nor relevant to consider systematically any non-anglo-saxon design as copied from, inspired by or equivalent to an anglo-saxon design (cf a recent post where the Tsybin RS-family was compared with the SR-71 or even the Bristol 188 (!) in complete disregard of timeline, operational requirements, and technologies used). The issue of technology transfer, legal or illegal, is often much more complex than just "copied" or "the Soviet equivalent of...". There is intelligence outside the anglo-saxon world. Why not look at it in its own right?
