IMO, sleeve valve radial aircraft engines were a technological dead end vs. poppet valve engines. In 1932 Bristol introduced their first sleeve valve engine, the Perseus. Up to this date Bristol was making poppet valve engines, such as the Jupiter and Mercury.
WI the British Air Ministry rejects all sleeve valve tech in 1930. How are RAF and FAA aircraft impacted in the interwar period?
What does Bristol make instead? Presumably they focus on the Bristol Pegasus? https://en.wikipedia.org/wiki/Bristol_Pegasus
Would they proceed with the Bristol Phoenix diesel design?
