... another reasonable, possible, early invetion, that never get the attention and funding it deserved. ... and therefore (almost) vanished.

But imo possible, if it had been picked up by some mayor wellnamed investor/company in the 20's.
Seek yout POD somewhere there ;).
 
Duke is only about the 200th* outfit at least trying to bring an axial piston engine to market. The virtues of the type being compactness and hopefully lower weight. The downside is you have a lot of heat generating parts in a closely confined space. Maybe Duke has the problems solved. Engines of this type have been used in some applications. The most successful use has been in torpedo applications. Longlife is not one of the design criteria here though

Thanks for agreeing with me by re-posting the link I posted, Kevin.

the Almen A4 18 cylinder aero engine was developing 425hp in 1924 with a gross weight of 700lb. If this engine entered production at that time then possibly wobble plate/barrel engines of 1000hp+ might be flying by 1940.
