I'm thinking the Russians stole that design from the English blueprints and designs of the first English fighter jet and its centrifugal compressor.
The airframe design was by captured Germans. They already had the airframe design done. The engine was a copy of the latest British engine.
At the end of the war, Britain voted Churchill out, and the new Liberal PM sold two of the British engines to the Soviets as a good will gesture.
The Soviet engine was never put in the airplane until they had mad a copy of the British engine.
Thank the British PM for Korea.
This is definitly wrong. The first MiG 15 had a English turbine (produced in licence) but the design was a taken from a German Focke Wulf Ta 183. The famous German aircraft designer Kurt Tank was the "father" of the MiG 15.
The MiG is not a German design, but benefitted from German aerodynamic research. Germany would have taken at least another two years to get a swept-wing jet into production, and that was two years that the Nazi regime didn't have. There was nothing but sketches of a MiG-like design in 1945.
The engine of the MiG-15 is a copy of a Rolls Royce Nene centrifugal-flow turbojet. Over various objections, the Labour government sold the Russians a small quantity, I believe 15, of these engines.
While the US got the leading rocket guys and aerodynamicists, the Russians scarfed up the leading turbojet guys, which helped the Russians make the move to axial compressors (as the Germans had been using) later in the fifties.
The only Allied nations to use significant numbers of Axis aircraft postwar were France and Czechoslovakia. France used Ju52s and Storches, for which she had profuction plants, and Nakajima Hayabusas, which were surrendered by Japan, for several years. Cs used the Me 262 briefly, and the Me 109 for a number of years, until after the Communist coup the Air Force was purged and Soviet model fighters were provided. The Czech republic (Reichsprotektorat Böhmen und Möhren) had the factories for 262, 109, Jumo 211 engines, and the smaller Walter aero engines.
Other nations used onesies and twosies for testing.
Some nations still operate the MiG-15 UTI (training variant), and Romania was still running Il-28s which use the same motor two years ago or so. There are some civilian registered MiG-15 and -15UTI in the USA. A dangerous plane, with high fuel burn and very long runways required. Without drop tanks (which cannot be dropped inflight, that mechanism must be disabled), and flying on internal fuel only, you barely have VFR reserves to fly the pattern.
