The Ford Trimotor is an American three-engined transport aircraft. Production started in 1925 by the companies of Henry Ford and ended on June 7, 1933, after 199 had been made. It was designed for the civil aviation market, but also saw service with military units.
The Avro 618 Ten or X was a passenger transport aircraft of the 1930s. It was a licensed version by Avro of the Fokker F.VIIB/3m.
The Fokker F.VII, also known as the Fokker Trimotor, was an airliner produced in the 1920s by the Dutch aircraft manufacturer Fokker, Fokker's American subsidiary Atlantic Aircraft Corporation, and several other companies under license. It was an airliner that could carry 6-12 people, depending on the version, and it used a variety of engines; early versions had one engine but three was more common.
The Boeing 80 was an American airliner of the 1920s. A three-engined biplane, the Model 80 was built by the Boeing Airplane Company for Boeing's own airline, Boeing Air Transport, successfully carrying both airmail and passengers on scheduled services.
The Fokker F.VIII was a large twin-engined airliner designed and produced by the Dutch aircraft manufacturer Fokker in the 1920s.
The Fokker Universal was the first aircraft built in the United States that was based on the designs of Dutch-born Anthony Fokker, who had designed aircraft for Germany during World War I. About half of the 44 Universals that were built between 1926 and 1931 in the United States were used in Canada. Among the famous pilots who flew the Fokker Universal were Punch Dickins and Walter Gilbert.
The Fokker F.IX was an airliner developed in the Netherlands in the late 1920s, intended to provide KLM with an aircraft suitable for regular services to the Dutch East Indies. When the onset of the Great Depression forced the postponement of those plans, the market for this aircraft disappeared as well, although it did see military service in Czechoslovakia as a bomber.
The Fokker F.XX was a 1930s Dutch three-engined airliner designed and built by Fokker. It was the first Fokker design to use an elliptical-section fuselage instead of the traditional square fuselage and the first Fokker aircraft with retractable landing gear.
The Fokker F.XXII was a 1930s Dutch four-engined 22-passenger airliner designed and built by Fokker.
The Fokker F-14 was an American seven/nine passenger transport aircraft designed by Fokker and built by their Atlantic Aircraft factory in New Jersey.
The Fokker F.XII was a three-engined high-winged monoplane airliner produced in the 1930s by the Dutch aircraft manufacturer Fokker. Two aircraft were built under license by Danish Orlogsværftet. The first was powered by 347 kW (465 hp) Bristol Jupiter VI radial engines and the second, an improved model, the F.XIIM, was about 20 km/h (12 mph) faster than the Dutch-built F.XIIs.
The Fokker S.IV was a military trainer aircraft produced in the Netherlands in the mid-1920s. It was a conventional, single-bay biplane with staggered wings of unequal span braced with N-struts, essentially a radial-engined development of the S.III. The pilot and instructor sat in tandem, open cockpits and the undercarriage was of fixed, tailskid type with a cross-axle between the main units. The Royal Netherlands Army Aviation Group purchased 30 examples and used them right up to the German invasion of the Netherlands in 1940. On 14 May that year, a few surviving S.IVs escaped to France alongside some S.IX trainers, but never flew again.
The Fokker Super Universal was an airliner produced in the United States in the late 1920s by Fokker America, an enlarged and improved version of the Fokker Universal, fitted with cantilever wings and an enclosed cockpit. It was also called the Model 8. It was subsequently also manufactured under license in Canada, and in Japan as the Nakajima-Fokker Super Universal and for the IJAAF as the Nakajima Ki-6 and later in the puppet state of Manchukuo as the Manshū Super Universal. It was used on the Byrd Antarctic expedition and was one of the most produced of the Fokker America models.
The Fokker F.XIV was a cargo plane built in the Netherlands in the late 1920s by Fokker. It was a high-wing cantilever monoplane of conventional trimotor layout. The sole example was tested by KLM but never put into service.
The PZL.4 was a Polish three-engine passenger aircraft for 10 passengers, built in PZL factory in 1932, which remained a prototype. It was the first Polish-designed and produced multi-engine plane.
The Junkers G 31 was an advanced tri-motor airliner produced in small numbers in Germany in the 1920s. Like other Junkers types, it was an all-metal, low-wing cantilever monoplane. In the mid-1920s, the all-metal construction and an aerodynamically 'clean' configuration were remarkable.
The Bach Air Yacht was a trimotor airliner produced in the United States in the 1920s. Typical of its day, it was a high-wing braced monoplane, with fixed tailwheel undercarriage. Unusual for airliners of the late 1920s, the Air Yachts were constructed almost entirely of wood with steel fittings, undercarriage, and struts. Different models were powered by varying combinations of Wright, Ryan-Siemens, Kinner, Comet, and Pratt & Whitney engines, a large engine in the nose of the aircraft, and two smaller "helpers" under the wings in nacelles supported by struts. As with so many aircraft companies of the late 1920s, the Bach Aircraft Company succumbed to the Great Depression, thus further development of the Air Yacht was abandoned after the 3-CT-9.
The Breda Ba.32 was an Italian airliner prototype designed and built by the Breda company.
The Kreutzer Air Coach is an American-built light trimotor transport aircraft of the late 1920s.
The Stout 2-AT Pullman, or "Air Pullman", was a single engine all-metal monoplane that was used for early airline travel and air mail transport in America.
