Abstract
An aircraft constructed with a push-pull configuration has a mixture of forward-mounted (tractor) propellers and backward-mounted (pusher) propellers. An early example of a "push-pull" aircraft was the Caproni Ca.I which had two wing mounted tractor propellers and one centre-mounted pusher propeller. Claudius Dornier was the first aviation designer to heartily embrace the concept for production aircraft, as many of his flying boats used variations of the tandem "push-pull" engine layout: Dornier Wal (1922), Dornier Do X (1929), Dornier Do 18 (1935), Dornier Do 26 (1938). While pure pushers decreased in popularity during the First World War, the push-pull configuration has continued to be used. The advantage it provides is the ability to mount two propellers on the aircraff's centreline, thereby avoiding the increased drag that comes with twin wing-mounted engines. It is also casier to fly if one of the two engines fails, as the thrust provided by the remaining engine is symmetrical in the horizontal plane. In contrast, a conventional twin-engine aircraft will yaw in the direction of the failed engine and become uncontrollable below a certain airspeed, known as Vmc, which varies with the type of aircraft Conventional push-pull designs, such as the Cessna Skymaster and Adam A500, have the engines mounted on the nacelle so that the aircraft's tail, suspended vis twin booms, is behind the pusher propeller. In contrast, both the World War II-era private plane had their pasher propeller at the rear of their fuselage.
