All Aircraft Engines

Powerplants built to propel heavier-than-air aircraft, spanning the piston radial and inline engines of the propeller era and the turbojet, turbofan and turboprop engines that followed. Belongs here: named aircraft engine families and specific models, whether piston or jet, civil or military. Does not belong here: automotive, locomotive or marine engines, even where an aircraft engine design was later adapted for another use.
