The so-called push/pull layout, combining the tractor and pusher configurations—that is, with one or more propellers facing forward and one or more others facing back—was another idea that continues to be used from time to time as a means of reducing the asymmetric effects of an outboard engine failure, such as on the Farman F.222, but at ...
Push-pull designs have the engines mounted above the wing as Dornier flying boats or more commonly on a shorter fuselage than conventional one, as for Rutan Defiant or Voyager canard designs. Twin boomers such as the Cessna Skymaster and Adam A500 have the aircraft's tail suspended via twin booms behind the pusher propeller.
A pusher aircraft is a type of aircraft using propellers placed behind the engines and may be classified according to engine/propeller location and drive as well as the lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft), Some aircraft have a Push-pull configuration with both tractor and pusher engines.

Rigid chain actuator. A rigid chain actuator, known variously as a linear chain actuator, push-pull chain actuator, electric chain actuator or column-forming chain actuator, is a specialized mechanical linear actuator used in window operating, push-pull material handling and lift applications.
The push-pull configuration provided centerline thrust, allowing simpler operation than the low-wing mounting of most twin-engine light aircraft, and allowed a high wing to be used, providing clear observation below and behind the aircraft.
Lower-than-average home prices and rent costs in Buffalo bolstered demand and helped to push it to the top spot. Meanwhile, Zillow attributes Indianapolis’s second-place spot to its strong home ...
The first successful airplanes to have a "tractor" configuration were the 1907 Santos-Dumont Demoiselle and Blériot VII.. The first biplane airplane to have a "tractor" configuration was the Goupy No.2 (first flight on 11 March 1909) designed by Mario Calderara and financed by Ambroise Goupy at the French firm Blériot Aéronautique.
