twin-engine
Pair of powerplants
Twin-engine describes aircraft or boats powered by two engines, typically one on each side: a twin-engine Cessna, twin-engine speedboat.
The configuration offers redundancy—if one engine fails, the other can maintain operation.
Also hyphenated as twin-engined, especially in British English.
