The largest radial engine ever to enter service, the Pratt & Whitney Wasp Major R-4360-59B, had four rows of seven cylinders.

In the video after the break, [Brick Technology] uses LEGO to gain some practical insight into the world of piston engine design, from single-cylinder all the way up to radial twelve-cylinder engines.

The engine works a lot like Infiniti’s VC Turbo, but the different cylinder layout means fewer moving parts, which the patent argues will make it more reliable. The radial engine has been ...

In the video after the break, [Brick Technology] uses LEGO to gain some practical insight into the world of piston engine design, from single-cylinder all the way up to radial twelve-cylinder engines.

While early models suffered losses against the Japanese Zeroes, switching to a Pratt and Whitney Double Wasp 18-cylinder turbocharged radial engine shifted the balance of power.
