It looked kind of cool actually, like a barrel and when you consider that Italians built it in 1932, it’s really really cool. The Caproni- Stipa was basically a hollow tube ducted fan engine. It’s performance was mediocre so the Italian Air Force demurred further advancement on the ducted fan experiments. This is proof that Italians didn’t always let style lead. Form followed function. This thing had two pilots.

 

 

What Caproni did here was calculate the exact dimensions of future jet engines. He also learned that this engine was markedly quieter than other engines, and operated more efficiently that many planes with similar wing loading. But it produced drag and this slowed it down considerably. It never exceeded 100 miles per hour.
