  1. What was known to both Whittle and his engineering team and the Germans was that axial flow enables as a more efficient engine, and it has less front area, so less aircraft drag. That's why the Germans persisted with it, but to get the advantages in practice requires a greater mastery of materials and a greater mastery of compressor blade design. The Germans never really mastered axial flow engine design before the war ended - their engines were not as efficient as they could have been, and their service life was very short. The Russians tried to get it right, starting with captured German engines and engineers, but it was taking too long, so they famously contracted with Rolls Royce to build centrifugal flow Nenes in Russia under license. Meanwhile in war-time Britain, Whittle was able to take advantage of Rolls Royce expertise in piston engine turbochargers, in which compressor design factors are exactly the same as in centrifugal jet engine compressor stages. So, lower stresses on parts plus existing British expertise led to the use of centrifugal flow until post war when Rolls Royce was able to use American axial flow know-how.
