Radial Engine

A radial engine is an internal combustion engine where the cylinders are arranged like spokes on a wheel, with the crankcase forming the hub. This design allows for a compact and lightweight engine with good power-to-weight ratio, making it ideal for use in aircraft. Radial engines were commonly used in airplanes during the 1930s and 1940s due to their ability to handle high altitudes and extreme weather conditions. Despite advances in technology, radial engines are still used today in specialized applications such as general aviation and marine engines.
