The Fokker Dr.I, often known simply as the Fokker Triplane, was a World War I fighter aircraft built by Fokker-Flugzeugwerke. The Dr.I saw widespread service in the spring of 1918. It became famous as the aircraft in which Manfred von Richthofen gained his last 17 victories, and in which he was killed on 21 April 1918.
The Fokker D.VII is a German World War I fighter aircraft designed by Reinhold Platz of the Fokker-Flugzeugwerke. Germany produced around 3,300 D.VII aircraft in the second half of 1918. In service with the Luftstreitkräfte, the D.VII quickly proved itself to be a formidable aircraft. The Armistice ending the war specifically required, as the fourth clause of the "Clauses Relating to the Western Front", that Germany was required to surrender all D.VIIs to the Allies. Surviving aircraft saw much service with many countries in the years after World War I.
The Fokker E.V was a German parasol-monoplane fighter aircraft designed by Reinhold Platz and built by Fokker-Flugzeugwerke. The E.V was the last Fokker design to become operational with the Luftstreitkräfte, entering service in the last months of World War I. After several fatal accidents due to wing failures, the aircraft was modified and redesignated Fokker D.VIII. Dubbed the Flying Razor by post-war pulp-fiction writers, the D.VIII had the distinction of scoring the last aerial victory of the war.
Motorenfabrik Oberursel A.G. was a German manufacturer of automobile, locomotive and aircraft engines situated in Oberursel (Taunus), near Frankfurt (Main), Germany. During World War I it supplied a major 100 hp-class rotary engine that was used in a number of early-war fighter aircraft designs. In 1921 the company merged with Deutz AG, and then again in 1930 with Humboldt-Deutz Motoren, and finally in 1938 with Klöcknerwerke AG. From this point on they were known as the Klöckner-Humboldt-Deutz Oberursel factory, known primarily for their locomotive engines. Today they are part of Rolls-Royce Deutschland, and produce one family of their jet engines.
Gnome et Rhône was a major French aircraft engine manufacturer. Between 1914 and 1918 they produced 25,000 of their 9-cylinder Delta and Le Rhône 110 hp (81 kW) rotary designs, while another 75,000 were produced by various licensees. These engines powered the majority of aircraft in the first half of the war, both Allied designs as well as German examples produced by Motorenfabrik Oberursel.
Le Rhône was the name given to a series of rotary aircraft engines built between 1910 and 1920. Le Rhône series engines were originally sold by the Société des Moteurs Le Rhône and, following a 1914 corporate buyout, by its successor company, Gnome et Rhône. During World War I, more than 22,000 nine cylinder Le Rhône engines were built, with the type far outselling Gnome et Rhône's other main wartime engine series, the Gnome Monosoupape.
The Le Rhône 9J is a nine-cylinder rotary aircraft engine produced in France by Gnome et Rhône. Also known as the Le Rhône 110 hp in a reference to its nominal power rating, the engine was fitted to a number of military aircraft types of the First World War. Le Rhône 9J engines were produced under license in Great Britain by W.H. Allen Son & Company of Bedford, and in Germany by Motorenfabrik Oberursel where it was sold as the Oberursel Ur.II.
The Pfalz D.VIII was a German World War I fighter aircraft.
The Fokker V.7 was a prototype German fighter triplane of World War I, an attempt to improve upon the Dr.I by using the experimental Siemens-Halske Sh.III, double acting rotary engine.. To make use of the higher power and rpm, the aircraft had a four-bladed propeller of larger diameter than the Dr.I. This required longer landing gear. The rear fuselage had to be extended to compensate for the heavier engine. Four V.7 aircraft were built. The performance of the V.7 was outstanding, but the engine was not ready for service. The Fokker V.7/I was converted to a Dr.I.
The Fokker V.1 was a small German sesquiplane experimental fighter prototype built in 1916 by the Fokker-Flugzeugwerke. Sporting a parasol wing, it was the first Fokker aircraft purportedly designed by Reinhold Platz—the respective roles played by Fokker himself, Platz, and possibly others in the conceptual design of Fokker airplanes are a matter of dispute among historians—and was an early experiment in cantilever wing construction, eliminating the bracing wires typical of aircraft design at the time, something that had already been achieved with metal materials in Hugo Junkers' own pioneering Junkers J 1 in 1915.
The Fokker D.VI was a German fighter aircraft built in limited numbers at the end of World War I. The D.VI served in the German and Austro-Hungarian air services.
The Fokker V.17 and its derivatives were a series of experimental monoplane Fighter aircraft produced by the Dutch aircraft company Fokker in the 1910s.
The Fokker M.6 was a two-seat experimental design resembling the later E.I fighter. It had a 60 kW (80 hp) Oberursel engine and first flew in June 1914.
The Fokker S.I was a Dutch primary trainer, first flown in 1919 and the first of a family of trainers from the Fokker company.
The Fokker S.II was a 1920s Dutch primary trainer built by the Fokker company for service with the Dutch Army.
The Fokker V.39 was a prototype sports aircraft built by Fokker shortly after World War I based on a scaled-down version of the Fokker D.VIII fighter design and powered by an 82 kW (110 hp) Le Rhône engine.
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 Kondor E 3, sometimes erroneously known as E.III, was a German single seat, monoplane fighter aircraft designed and built close to the end of World War I. Though successful in the third D-type fighter competition at Aldershof in September 1918, only a few were produced, given the Idflieg designation of Kondor D.I.
The Sands Fokker Dr.1 Triplane is an American homebuilt aircraft that was designed by Ron Sands Sr of Mertztown, Pennsylvania, and produced by Wicks Aircraft and Motorsports. It is a full-sized replica fighter aircraft based upon the 1917-vintage Fokker Dr.1. The aircraft is supplied as a kit and in the form of plans for amateur construction.
In October 1917 Nieuport began construction of a prototype monoplane fighter known as the Nieuport Madon, a strut braced monoplane.
