Radial Engine

A radial engine is an internal combustion engine that has its cylinders arranged around a central hub, resembling the spokes of a wheel. It was commonly used in aircraft during the early to mid-20th century due to its high power-to-weight ratio and ability to produce large amounts of horsepower. The radial engine design allowed for efficient cooling, as air could easily circulate around the cylinders, making it ideal for use in aviation.
