This Design Quietly Solved the Big Problem with Radial Engines

Support me on Patreon :   / letsgoaviate   The Zoche Aero-Diesel is almost a revival of the Packard DR-980, except Zoche actually got the Aero-diesel's design right. Not only that, they managed to make a radial engine small enough to compete with horizontally opposed engines. How did they accomplish that? Let's explore the fascinating design of the Zoche Aero-diesel. The Zoche patent: https://patents.google.com/patent/US5...
