The weirdest design I've seen

Those engines were used on early airplanes, I never knew there were cars equiped with those.
Kind of leaky and noisy!

O yeah, it sounds old and beautifull, well broken in!

The difference is that the radial engine commonly used on propeller-driven airplanes are usually stationary. The cylinders don't move, and the pistons drive a center crankshaft that spins the prop. I've never seen one where the cylinders themselves spin around. Cool!

There was a brand of aero engine called Franklin that had the cylinders rotate with the propellers. Must have been a challenge to balance it though.

Some spin the engine with a stationary crank, to improve cylinder cooling.

This one for example

Aircrafts with this kind of engine were hard to fly and manoeuvre, because of the gyroscopic effects. They usually turned one way. I believe the sopwith camel had this kind of engine, without a throttle, just an on/off switch. Power was controlled by blipping the switch.
