Dunne D.4
The Dunne D.1, was an experimental tailless aircraft built in the UK in 1907. It comprised a main unit which could be flown as a glider, to which a chassis unit with power train could be added. The glider achieved a short flight in 1907. The D.1 was later rebuilt as the powered D.4, which achieved short hops in 1908. Origins Lieutenant J. W. Dunne was employed by the Army Balloon Factory at Farnborough in 1906, to develop full-size aircraft based on his previous work with tailless, swept-wing models which were inherently stable. The key feature which gave them stability was a conical upper wing surface, arranged to give a progressive decrease in the angle of incidence towards the wingtips, a feature known as washout. Dunne and the Balloon Factory's Commander, Col. J.E. Capper, wanted him to build a monoplane, but the Army insisted on a biplane, believing it to be both lighter and stronger.

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by '' Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

Pusher Aircraft
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific (propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplanes) were ...

Tailless Aircraft
In aeronautics, a tailless aircraft is an aircraft with no other horizontal aerodynamic surface besides its main wing. It may still have a fuselage, vertical tail fin (vertical stabilizer), and/or vertical rudder. Theoretical advantages of the tailless configuration include low parasitic drag as on the Horten H.IV soaring glider and good stealth characteristics as on the Northrop B-2 Spirit bomber. Disadvantages include a potential sensitivity to trim. Tailless aircraft have been flown since the pioneer days; the first stable aeroplane to fly was the tailless Dunne D.5, in 1910. The most successful tailless configuration has been the tailless delta, especially for combat aircraft, though the most familiar tailless delta is the Concorde airliner. NASA has used the 'tailless' description for the novel X-36 research aircraft which has a canard foreplane but no vertical fin. Aircraft configuration A tailless aircraft has no other horizontal surface besides its main wing. The aer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glider Aircraft
A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. Most gliders do not have an engine, although motor-gliders have small engines for extending their flight when necessary by sustaining the altitude (normally a sailplane relies on rising air to maintain altitude) with some being powerful enough to take off by self-launch. There are a wide variety of types differing in the construction of their wings, aerodynamic efficiency, location of the pilot, controls and intended purpose. Most exploit meteorological phenomena to maintain or gain height. Gliders are principally used for the air sports of gliding, hang gliding and paragliding. However some spacecraft have been designed to descend as gliders and in the past military gliders have been used in warfare. Some simple and familiar types of glider are toys such as paper planes and balsa wood gliders. Etym ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dunne Aircraft
Dunne is an Irish surname, derived from the Irish ''Ó Duinn'' and ''Ó Doinn'', meaning "dark" or "brown." The name Dunne in Ireland is derived from the Ó Duinn and the Ó Doinn Gaelic septs who were based in County Laois, County Meath and County Wicklow. These septs in turn are descendants of the O'Regan noble family. It is in these counties that the majority of descendants can still be found. Hundreds of years ago, the Gaelic name used by the Dunn family in Ireland was Ó Duinn or Ó Doinn. Both Gaelic names are derived from the Gaelic word ''donn'', which means "brown". Ó Doinn is the genitive case of ''donn''. First found in county Meath, where they held a family seat from very ancient times. Variations: Dunn, Dunne, Dun, Duen, O'Dunne, O'Doyne, Doine, Doin, O'Dunn. Dunne Castles The Dunnes formerly owned a number of castles in the midlands of Ireland. Today little remains of most of these castles, many were destroyed during the Cromwellian Invasion of Ireland. Tinnahinch ...

Igo Etrich
Ignaz "Igo" Etrich (25 December 1879 – 4 February 1967) was an Austrian flight pioneer, pilot and fixed-wing aircraft developer. Education Etrich was born on Christmas Day 1879 in the Upper Old Town of Trutnov, Bohemia. He attended school in Leipzig, where he came in contact with the works of Otto Lilienthal. His main interest was in aviation, the problems of bird flight. With his father, a factory-owner, he built a laboratory for developing aeroplanes. After the death of Lilienthal, Etrich's father acquired some advanced gliders. Aviation Prof. Ahlborn had published a paper in 1897, in which he had described the flying seed of '' Zanonia macrocarpa''. Etrich and his co-worker Franz Xaver Wels designed an unmanned glider of similar form and flew it successfully in 1904. Attempts to add an engine failed, but a successful manned glider was flown in 1906."The Evolution of the Etrich 'Taube'", ''Flight'' 12 February 1915, pp.106-10/ref> He also worked with Karl Illner.

British Army Aeroplane No 1
The British Army Aeroplane No 1 or sometimes Cody 1 was a biplane built by Samuel Franklin Cody in 1907 at the Army Balloon Factory at Farnborough. It made the first recognised powered and sustained flight in the United Kingdom on 16 October 1908. Background In the early years of the twentieth century, the British Army's limited interest in aeronautical matters was largely confined to the use of tethered balloons or kites for artillery observation purposes. Many people did not believe the Wright Brothers' claims of sustained controlled flight, and in 1907 an officially sanctioned experiment at the Balloon Factory, Farnborough, was limited to the building of the Dirigible No. 1 ''Nulli Secundus'', which was the Army's first powered airship, under the supervision of Colonel J. E. Capper, the superintendent of the factory. In addition some highly secret experiments with gliders were being carried out at Blair Atholl in Scotland by J. W. Dunne in collaboration with Capper.

Elevon
Elevons or tailerons are aircraft control surfaces that combine the functions of the elevator (used for pitch control) and the aileron (used for roll control), hence the name. They are frequently used on tailless aircraft such as flying wings. An elevon that is not part of the main wing, but instead is a separate tail surface, is a stabilator (but stabilators are also used for pitch control only, with no roll function, as on the Piper Cherokee series of aircraft). Elevons are installed on each side of the aircraft at the trailing edge of the wing. When moved in the same direction (up or down) they will cause a pitching force (nose up or nose down) to be applied to the airframe. When moved differentially, (one up, one down) they will cause a rolling force to be applied. These forces may be applied simultaneously by appropriate positioning of the elevons e.g. one wing's elevons completely down and the other wing's elevons partly down. An aircraft with elevons is controlled ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Engineers
The Corps of Royal Engineers, usually called the Royal Engineers (RE), and commonly known as the ''Sappers'', is a corps of the British Army. It provides military engineering and other technical support to the British Armed Forces and is headed by the Chief Royal Engineer. The Regimental Headquarters and the Royal School of Military Engineering are in Chatham in Kent, England. The corps is divided into several regiments, barracked at various places in the United Kingdom and around the world. History The Royal Engineers trace their origins back to the military engineers brought to England by William the Conqueror, specifically Bishop Gundulf of Rochester Cathedral, and claim over 900 years of unbroken service to the crown. Engineers have always served in the armies of the Crown; however, the origins of the modern corps, along with those of the Royal Artillery, lie in the Board of Ordnance established in the 15th century. In Woolwich in 1716, the Board formed the Royal Regime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
