The Rise & Fall of the Radial Airplane Engine - History & Technical

The Radial engine was once the pinnacle of internal combustion engine design, but has gone mostly extinct. What happened? The Radial first ousted the Rotary, then to a large extent the inline engines (V12's) before the Radial itself was ousted. In this video we briefly go through the history of the radial and we also take a bit of a deep dive into radial engine design and see what made it such a great engine.
