Radial engine

A radial engine is an internal combustion engine where the cylinders are arranged in a "V" shape around a central crankshaft, resembling a wheel's spokes radiating from its hub. This type of engine was commonly used in aircraft during the early to mid-20th century before being replaced by more efficient designs. Despite being less common today, radial engines are still used in certain applications like vintage airplanes and marine engines.
