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.
Swept propeller Scimitar propeller on a 1926 Alexander Eaglerock Eight-blade scimitar propellers on the Airbus A400M Atlas. A scimitar propeller is a type of propeller that has curved blades with increasing sweep along the leading edge. Their name is derived from their visual similarity to the curved blades of scimitars.
A pusher aircraft is a type of aircraft using propellers placed behind the engines. Pushers may be classified according to lifting surfaces layout (conventional or 3 surface, canard, joined wing, tailless and rotorcraft) as well as engine/propeller location and drive. For historical interest, pusher aircraft are also classified by date.

Counter-rotating propellers World War I Linke-Hofmann R.I German heavy bomber (1917) with counter-rotating propellers He 177A Greif with counter-rotating propellers. Counter-rotating propellers (CRP) are propellers which turn in opposite directions to each other. [1] They are used on some twin- and multi-engine propeller-driven aircraft.
This was done because UltraFlight had ample supplies of the existing propellers and using them saved money over developing a new propeller. [12] Also, since inception, the Lazair was designed as a powered glider, so stacking of the two propellers in a bi-plane mode created a propeller that had less drag when gliding than if the 4 blades were 90 ...
Quicksilver Aircraft is an American manufacturer of ultralight and light aircraft.Founded in 1972 as Eipper Formance and later Eipper Aircraft, [1] the company today claims to be the leading manufacturer of ultralight aircraft in the United States, [2] with the Quicksilver type ultralight being used to train more ultralight pilots than any other type.
A two-bladed propeller would therefore obstruct the gun six times every firing cycle of the gun, a four-bladed one twelve times. A gun set up this way would be interrupted more than forty times per second, [2] while firing at only around seven rounds per second. Unsurprisingly, the designers of so-called interrupter gears found this too ...
