A Radial engine is an internal combustion engine that arranges its cylinders in a circular pattern around a central crankshaft. This design offers advantages such as more uniform cooling and better weight distribution, making it ideal for aircraft usage during the early 20th century. These engines were commonly used in airplanes like the Douglas DC-3 and the Lockheed Constellation. Despite the advancements in technology, some modern aircraft still utilize radial engines for specific purposes.
