The Acme Aircraft Co S-1 Sierra was an experimental aircraft of unusual configuration built in the US in 1948 to investigate the advantages of a pusher propeller configuration. Apart from this engine installation, the aircraft was unusual in having an X-shaped tail incorporating ruddervators on the upper fins. The wing was mounted midway up the fuselage and was unswept. During the 1960s, the US aerospace manufacturer Northrop used the aircraft as a technology demonstrator for boundary layer control concepts.
The Republic XP-69 was an American fighter aircraft proposed by Republic Aviation in 1941 in response to a requirement by the United States Army Air Corps for a high-speed fighter. Manufacturers were encouraged to consider unorthodox designs; although the design was ordered as a prototype it was canceled because of delays with the engine that was to power it.
The Aerosport Rail is an American minimalist ultralight aircraft, designed by Harris Woods and built by Aerosport Inc. The aircraft was first flown on 14 November 1970.
The Avtek 400A was an American prototype turboprop-powered business aircraft, which was developed in the early 1980s. Its configuration was unusual and distinctive : a low-wing monoplane with two pusher engines mounted above the wings, and a large canard mounted atop the forward fuselage. The aircraft's sleek, futuristic design earned it a guest appearance on the Airwolf TV series as the X-400, which was used by the villain, Lou Stappleford in the Eagles episode.
The Bartlett LC-13A Zephyr 150 was a United States light civil aircraft built in the 1940s. It was a mid-wing braced monoplane of conventional design with side-by-side seating for two and fixed, tailwheel undercarriage. It was originally marketed as the Babcock LC-13 by its original manufacturer, then as the Taubman LC-13 when the Babcock Airplane Corporation was acquired by Taubman Aircraft. The rights were finally acquired by Bartlett Aircraft in 1941, but plans to mass-produce it were halted by the outbreak of World War II. There was a brief attempt to revive the design at the end of the war, but nothing came of this.
The Fokker F.25 Promotor, first flown in 1946, was a single-engined, twin-boomed, four-seat passenger monoplane with a pusher engine mounted at the rear of a central nacelle. It was of wooden construction and has fitted with a retractable nosewheel undercarriage. One feature of the design was that instead of a 2 + 2 seating, the pilot sat in front to the left, and all three passengers were on a bench seat to the rear of him. Alternatively, when being used as an air ambulance aircraft, it could carry a patient on a stretcher, which was loaded through a hatch in the aircraft's nose. The F.25 was evocative of the pre-war G.I design.
The Colonial Model C-1 Skimmer was an American small single-engined amphibian flying boat built by the Colonial Aircraft Corporation. It was the start of a line of very similar aircraft designed by David Thurston.
The SECAN SUC-10 Courlis was a French high-wing touring monoplane designed and built by Société d'Etudes et de Construction Aéronavales (SECAN), a branch of the automobile company Société des Usines Chaussons. The aircraft had problems with the engine installation and only 144 were built, some without engines and were scrapped.
The channel wing is an aircraft wing principle developed by Willard Ray Custer in the 1920s. The most important part of the wing consists of a half-tube with an engine placed in the middle, driving a propeller placed at the rear end of the channel formed by the half-tube.
The Stout Skycar was a series of four one-off American light aircraft of the 1930s.
The Waco Model W Aristocraft was an American four-seat monoplane, the last aircraft designed and built by the Waco Aircraft Company. It had an unusual configuration with an engine mounted at the front driving a pusher propeller at the rear.
The Custer Channel Wing was a series of American-built experimental aircraft designs of the 1940s and 1950s incorporating a half-barrel shaped section to each wing.
The Baumann Brigadier was a prototype American light transport aircraft of the late 1940s. It was a twin-engined monoplane, which, unusually, was of pusher configuration. Only two were built, plans for production never coming to fruition.
The Aeronca 12AC Chum was a 2-seat cabin monoplane designed and produced by Aeronca in the United States in 1946. The design was a licence-built version of the ERCO Ercoupe.
The Douglas Cloudster II was an American prototype five-seat light aircraft of the late 1940s. It was of unusual layout, with two buried piston engines driving a single pusher propeller. Only a single example was built, which flew only twice, as it proved too expensive to be commercially viable.
The Savoia-Marchetti SM.80 is a two-seat monoplane amphibian tourer, with a single, tractor engine mounted above the wing, designed in Italy in the early 1930s. The SM.80bis is a four-seat variant, powered by two pusher engines.
The Sud-Est or SNCASE SE-2100, sometimes known as the Satre SE-2100 after its designer, was a tailless, pusher configuration touring monoplane with a single engine and cabin for two. Only one was built.
The Miller JM-2 was an American Formula One Air Racing homebuilt aircraft that was designed by Jim W Miller and produced by JW Miller Aviation of Marble Falls, Texas. When it was available, the aircraft was supplied in the form of plans for construction by amateurs.
The Williams W-17 Stinger is an American homebuilt racing aircraft that was designed for Formula One Air Racing by Art Williams and produced by his company, Williams Aircraft Design of Northridge, California, introduced in 1971. The aircraft was at one time available in the form of plans for amateur construction, but only one was ever constructed.
The Ireland Neptune was a four or five place pusher configuration biplane sold in flying boat and amphibian versions. Designed in the U.S. and first flown in 1927, well over 50 were built.
