Design and development

After selling a small quantity of PS / RS patrol / transport amphibians to the Navy, Sikorsky (then a division of United Aircraft Corporation) endeavoured to interest the service in a patrol flying boat. Having received a development contract in mid-1930, Sikorsky delivered a complete aircraft for testing in June 1932.[1] The XP2S-1, as the prototype was designated, was a two-bay, equal-span biplane of mixed construction. Its two R-1340 Wasp radial engines were mounted in a single nacelle in a tandem configuration. Its overall performance did not exceed that of other biplane patrol boats of the era, and after approximately one year of official trials the Navy cancelled the project.[1]

List of pusher aircraft by configuration

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. The list includes these even if the pusher engine is just added to a conventional layout (engines inside the wings or above the wing for example).
