Pusher configuration

In aeronautical and naval engineering, pusher configuration is the term used to describe a drivetrain of air- or watercraft with propulsion device(s) after the engine(s). Amongst aircraft, the more conventional design is the tractor configuration, which places them in front.

Though the term is most commonly applied to aircraft, its most ubiquitous propeller example is a common outboard motor for a small boat.

“Pusher configuration” describes the specific (propeller or ducted fan) thrust device attached to a craft, either aerostats (airship) or aerodynes (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboats, and propeller-driven snowmobiles.
