Radial Engine

A radial engine is an internal combustion engine that has its cylinders arranged like spokes of a wheel around a central crankshaft. This configuration allows for compact and efficient design, making it suitable for use in aircraft during the early 20th century. The radial engine's cylinders were often air-cooled, which helped prevent overheating at high altitudes where temperatures can be extreme. Despite its historical significance, the radial engine has been largely replaced by more modern engine designs in modern aviation.
