American and US companies were already working on axial flow designs
before the end of the war. They knew very well that the centrifugal
design had a limited scope for development but they also knew
it would be easier to produce a reliable engine that way. This
turned out to be correct.

Could argue that - in Britain at least - we lost interest in the
centrifugal flow engine just a touch too early. There was very little
interest in the Nene, IIRC, which is why it was regarded as OK to
sell the design to Russia (while hanging on tight to the Sapphire
and Avon). Of course, the Nene worked very well in MiG15 (and also,
IIRC, in the Tunnen as well as a few other designs). In fact it must
have been the last centrifugal flow engine to power an aircraft in
combat - when did the Indian Sea Hawks go?

Mid-'80s IIRC, but there were MiG-17/-17Fs (VK-1/1F, a Nene copy) )in
combat (Vietnam 1972, Oct. 73, plus probably smaller wars since that Vic
Flintham will no doubt list) after the Sea Hawks (Dec. 1971) last fired in
anger.
