Radial engine

grabcad

A radial engine is an internal combustion engine where the cylinders are arranged like spokes in a wheel around a central crankshaft, with the pistons moving outward from the center. This configuration was commonly used in aircraft engines during the 1930s and 1940s due to its ability to balance forces evenly and provide a compact design. Today, radial engines can still be found in certain applications such as marine and aviation use.
