There is a world of difference betwixt a rotary and a radial......

So much so it's enough to make your head spin.

Interesting looking thing

At least that one wouldn't fall over when you blip the throttle......

Alan Millyard's Flying Millyard has an engine made from two barrels and pistons from a Pratt and Whitney radial aero engine. It's 5l, the pistons are huge!!

And the crank case (but not the crank...).

Early rotaries,like Sopwith Camels, have the crank stationary and the cylinders spin, but someone worked out this was stupid, and on most rotary engines the crank spins and the cylinders are stationary.

That's the difference between a rotary and a radial engine, the cylinder layout is the same.

The clue is in the name...Rotaries rotate...Radials spin in unseen ways...

[Mr. Dazzle]

Pfft, all engines hold on to the crank and spin the entire universe around, everyone knows that.

It wasn’t stupid at the time. The rotary had a high power to weight ratio (compared to other contemporary engines) and didn’t vibrate the airframe to bits.

It was overtaken by developments in radial, inline and V-configuration engines.
