radial engine
Aeron.
an internal-combustion engine having the cylinders arranged in radial opposition, found mainly on older aircraft.
[1905-10]

* * *

Type of internal-combustion engine used mainly in small airplanes, in which the cylinders (ranging from five to as many as 28, depending on engine size) are mounted in a circle around the crankshaft, sometimes in banks of two or more.

Once the dominant piston-engine type, radials are now in only limited production; most new requirements are met by remanufacturing existing stock.
