A radial engine is an aircraft engine where the cylinders are arranged like spokes on a wheel around a central crankshaft, with the pistons radiating outward from the center. This type of engine is known for its robustness and ability to produce power even at high altitudes and under extreme conditions. It was widely used in aircraft during the early to mid-20th century but has mostly been replaced by more modern engines in modern aviation.
