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).

Sikorsky Aircraft

The Sikorsky Aircraft Corporation is an American aircraft manufacturer based in Stratford, Connecticut. It was established by Igor Sikorsky in 1923 and was among the first companies to manufacture helicopters for civilian and military use.

Previously owned by United Technologies Corporation (UTC), in November 2015 Sikorsky was sold to Lockheed Martin.
