radial engine

A radial engine is an internal combustion engine where the cylinders are arranged in a "V" or "W" formation around a central crankshaft, with each cylinder's piston connecting to a common crankpin. This design allows for more efficient cooling and better weight distribution compared to other engine types. Radial engines were commonly used in aircraft during the early to mid-20th century, particularly in smaller planes and military aircraft.
