Triplane
A triplane is a fixed-wing aircraft equipped with three vertically stacked wing planes. Tailplanes and canard foreplanes are not normally included in this count, although they occasionally are. Design principles The triplane arrangement may be compared with the biplane in a number of ways. A triplane arrangement has a narrower wing chord than a biplane of similar span and area. This gives each wing-plane a slender appearance with higher aspect ratio, making it more efficient and giving increased lift. This potentially offers a faster rate of climb and tighter turning radius, both of which are important in a fighter. The Sopwith Triplane was a successful example, having the same wing span as the equivalent biplane, the Sopwith Pup. Alternatively, a triplane has reduced span compared to a biplane of given wing area and aspect ratio, leading to a more compact and lightweight structure. This potentially offers better maneuverability for a fighter, and higher load-capacity w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Quadruplane
In aviation, a multiplane is a fixed-wing aircraft-configuration featuring multiple wing planes. The wing planes may be stacked one above another, or one behind another, or both in combination. Types having a small number of planes have specific names and are not usually described as multiplanes: * Biplane - two wings stacked one above the other * Triplane - three wings stacked one above another * Tandem wing - two main planes, one behind the other. The tandem triple or tandem triplet configuration has three lifting surfaces one behind another. While triplane, quadruplane and tandem designs are relatively uncommon, aircraft with more than four sets of wings rarely occur - none have proven successful. Quadruplanes The quadruplane configuration takes the triplane approach a step further, using efficient wings of high aspect ratio and stacking them to allow a compact and light weight design. During the pioneer years of aviation and World War I, a few designers sought these potential ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sopwith Triplane
The Sopwith Triplane was a British single seat fighter aircraft Fighter aircraft are fixed-wing military aircraft designed primarily for air-to-air combat. In military conflict, the role of fighter aircraft is to establish air superiority of the battlespace. Domination of the airspace above a battlefield ... designed and manufactured by the Sopwith Aviation Company during the World War I, First World War. It has the distinction of being the first military triplane to see operational service. The Triplane was developed by the firm's experimental department as a private venture, the project was headed by the designer Herbert Smith (engineer), Herbert Smith. Aside from its obvious difference in wing configuration, the aircraft shared many similarities with the company's successful biplane fighter, the Sopwith Pup. The prototype Triplane performed its maiden flight on 28 May 1916 and was dispatched to the Western Front (World War I), French theatre two months later, where i ...

Fokker D
Fokker was a Dutch aircraft manufacturer named after its founder, Anthony Fokker. The company operated under several different names. It was founded in 1912 in Berlin, Germany, and became famous for its fighter aircraft in World War I. In 1919 the company moved its operations to the Netherlands. During its most successful period in the 1920s and 1930s, it dominated the civil aviation market. Fokker went into bankruptcy in 1996, and its operations were sold to competitors. History Fokker in Germany At age 20, while studying in Germany, Anthony Fokker built his initial aircraft, the ''Spin'' (Spider)—the first Dutch-built plane to fly in his home country. Taking advantage of better opportunities in Germany, he moved to Berlin, where in 1912, he founded his first company, Fokker Aeroplanbau, later moving to the Görries suburb just southwest of Schwerin (at ), where the current company was founded, as Fokker Aviatik GmbH, on 12 February 1912.

Ellehammer Triplane
__NOTOC__ The Ellehammer triplane was a pioneering aircraft built in Denmark in 1907. Unlike Ellehammer's semi-biplane of the previous year, this (otherwise unnamed) triplane was capable of making free, untethered flights. The aircraft featured three sets of triangular wings attached to an open tubular framework. The upper set was one continuous-span, but the lower sets were split and attached either side of the frame. A horizontal stabiliser was fitted aft of the frame. There were no conventional vertical stabilizers, however the covered tailwheel provided a very small amount of surface area for stability. On 14 January 1908 Ellehammer achieved a flight in this machine of 175 m (574 ft) and on 13 February, one of 300 m (1,000 ft). Around this time, he also started making curved flights. In June, Ellehammer demonstrated the triplane in Kiel, where he was able to collect a M 5,000 prize from Prince Henry of Prussia for making a powered flight in Germany. ...

Jacob Ellehammer
Jacob Christian Hansen-Ellehammer (14 June 1871 – 20 May 1946) was a Danish watchmaker and inventor born in Bakkebølle, Denmark. He is remembered chiefly for his contributions to powered flight. Following the end of his apprenticeship as a watchmaker, he moved to Copenhagen where he worked as an electronics mechanic before establishing his own company in 1898. In the beginning he produced cigarette machines, beverage machines and other electronic machinery. In 1904 he produced his first motorcycle, the Elleham motorcycle. The Elleham motorcycle is of step-tru type with the engine situated beneath the seating, thus predating the Vespa scooter by 40 years. In 1903–1904 Jacob Hansen-Ellehammer used his experience constructing motorcycles fitted with single-cylinder Peugeot Frères engines to build the world's first air-cooled radial engine, a three-cylinder engine by utilizing Peugeot Frères cylinders and heads in a home-cast engine block. The initial engine soon proved to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roe I Triplane
The Roe I Triplane (often later referred to as the Avro Triplane) was an early aircraft designed and built by A.V. Roe which was the first all-British aircraft to fly.Jackson 1990 p.6 (Roe's previous biplane had a French engine). Background After being evicted from Brooklands, where he had worked on his first aircraft, Roe started work in July 1908 on the design of a triplane: a patent was filed for this design in January 1909,Jackson 1990 p.4 and work was started on the construction of an aircraft of this design in the stable adjoining the house of his brother, Dr Spencer Verdon Roe, in Putney in South-West London. It was then transported to the new flying ground that Roe had found on Walthamstow Marshes (then in Essex, but now within the London Borough of Waltham Forest), where he rented two railway arches under the LNER railway besides the river Lea. Design and development The Roe I Triplane was a two-bay triplane: the tailplane, with a span of also had three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alliot Verdon Roe
Sir Edwin Alliott Verdon Roe OBE, Hon. FRAeS, FIAS (26 April 1877 – 4 January 1958) was a pioneer English pilot and aircraft manufacturer, and founder in 1910 of the Avro company. After experimenting with model aeroplanes, he made flight trials in 1907–1908 with a full-size aeroplane at Brooklands, near Weybridge in Surrey, and became the first Englishman to fly an all-British machine a year later, with a triplane, on the Walthamstow Marshes. Early life Roe was born in Patricroft, Eccles, Lancashire, the son of Edwin Roe, a doctor, and Annie Verdon. He was the elder brother of Humphrey Verdon Roe. Roe left home when he was 14 to go to Canada where he had been offered training as a surveyor. When he arrived in British Columbia he discovered that a slump in the silver market meant that there was little demand for surveyors, so he spent a year doing odd jobs, then returned to England. There he served as an apprentice with the Lancashire & Yorkshire Railway. He later tried t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Émile Dorand
Jean-Baptiste Émile Dorand (14 May 1866 – 1 July 1922), was a French military engineer and aircraft designer. Early career Émile Dorand was born in Semur-en-Auxois in eastern France. He attended the École Polytechnique from 1886 to 1888 in the Latin Quarter of Paris. He then went to the Fontainebleau Application School, a military college, which he left after two years as a Lieutenant in the French Army. In an engineering regiment, he met the airship pioneer Charles Renard, and was soon authorised to direct free balloon flights. He studied aeronautics and the problems of flight including working to improve kites, long range photography, and flight test methodology. From 1895 to 1896, he was assigned to the Expeditionary Engineer Corps with whom he managed hydrogen balloons and bridging equipment in Madagascar.

Caproni Ca
Caproni, also known as ''Società de Agostini e Caproni'' and ''Società Caproni e Comitti'', was an Italian aircraft manufacturer. Its main base of operations was at Taliedo, near Linate Airport, on the outskirts of Milan. Founded by Giovanni Battista "Gianni" Caproni during 1908, the company produced several successful heavy bombers during the First World War. Following the acquisition of several other aviation firms throughout the interwar period, Caproni transformed into a sizable aviation-orientated syndicate, the ''Società Italiana Caproni, Milano''. The majority of its aircraft were bombers and transport aircraft. It played a pioneering role in the development of the Caproni Campini N.1, an experimental aircraft powered by a thermo-jet. It provided large numbers of combat aircraft for the Axis during the Second World War. The firm did not prosper in the postwar era, the Società Italiana Caproni collapsing during 1950. Many of the company's former assets were subseque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabane Strut
In aeronautics, bracing comprises additional structural members which stiffen the functional airframe to give it rigidity and strength under load. Bracing may be applied both internally and externally, and may take the form of strut, which act in compression or tension as the need arises, and/or wires, which act only in tension. In general, bracing allows a stronger, lighter structure than one which is unbraced, but external bracing in particular adds drag which slows down the aircraft and raises considerably more design issues than internal bracing. Another disadvantage of bracing wires is that they require routine checking and adjustment, or rigging, even when located internally. During the early years of aviation, bracing was a universal feature of all forms of aeroplane, including the monoplanes and biplanes which were then equally common. Today, bracing in the form of lift struts is still used for some light commercial designs where a high wing and light weight are more imp ...
