Dunne D.6
The Dunne D.7 was one of J. W. Dunne's swept wing tailless aircraft designed to have automatic stability, first flying in 1911. It was a single seat, single engined pusher monoplane developed from the unsuccessful D.6. Design and development Although J. W. Dunne is best known for his inherently stable tailless biplanes such as the D.8, he also developed a series of inherently stable monoplanes. He first submitted a monoplane design to the War Office when he joined the Army Balloon Factory at Farnborough in 1906, but they told him to build a biplane instead. D.6 It wasn't until Dunne left the Balloon Factory and started his own company, the Blair Atholl Aeroplane Syndicate Ltd., that a monoplane could be built. The D.6 was built by Dunne's old commanding officer, Col. J. E. Capper who was also a member of his Blair Atholl Aeroplane Syndicate. It was finished in 1911, with a 60 hp (45 kW) Green in a pusher configuration. Three A-frames supported the wing engine, pil ...

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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Camber (aerodynamics)
In aeronautics and aeronautical engineering, camber is the asymmetry between the two acting surfaces of an airfoil, with the top surface of a wing (or correspondingly the front surface of a propeller blade) commonly being more convex (positive camber). An airfoil that is not cambered is called a ''symmetric airfoil''. The benefits of cambering were discovered and first utilized by George Cayley in the early 19th century. Overview Camber is usually designed into an airfoil to maximize its lift coefficient. This minimizes the stalling speed of aircraft using the airfoil. An aircraft with cambered wings will have a lower stalling speed than an aircraft with a similar wing loading and symmetric airfoil wings. An aircraft designer may also reduce the angle of attack of the outboard section of the wings. This ensures that, as the aircraft approaches the stall, the wing root stalls before the tip, giving the aircraft resistance to spinning and maintaining aileron effectiveness c ...

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 ...

1910s British Experimental Aircraft
Year 191 ( CXCI) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Apronianus and Bradua (or, less frequently, year 944 ''Ab urbe condita''). The denomination 191 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Société Astra
''Société Astra des Constructions Aéronautiques'' was a major French manufacturer of balloons, airships, and aeroplanes in the early 20th century. It was founded in 1908 in aviation, 1908 when Henri Deutsch de la Meurthe purchased Édouard Surcouf's ''Flight'' workshops at Boulogne-Billancourt, Billancourt. Its most significant products were the Astra-Torres airships, but beginning in 1909 in aviation, 1909, the firm also produced Wright brothers heavier-than-air designs under licence. In 1912 in aviation, 1912, these were supplanted by Astra's own designs, the Astra C and Astra CM, CM. Astra Clément-Bayard Astra Clément-Bayard was established in 1908 by Astra and French industrialist Adolphe Clément-Bayard, to manufacture airships at a new factory in Trosly-Breuil, L ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gnome Rotary Engine
A gnome is a mythological creature and diminutive spirit in Renaissance magic and alchemy, first introduced by Paracelsus in the 16th century and later adopted by more recent authors including those of modern fantasy literature. Its characteristics have been reinterpreted to suit the needs of various story tellers, but it is typically said to be a small humanoid that lives underground. Diminutive statues of gnomes introduced as lawn ornaments during the 19th century grew in popularity during the 20th century and came to be known as garden gnomes. History Origins The word comes from Renaissance Latin ''gnomus'', which first appears in ''A Book on Nymphs, Sylphs, Pygmies, and Salamanders, and on the Other Spirits'' by Paracelsus, published posthumously in Nysa in 1566 (and again in the Johannes Huser edition of 1589–1591 from an autograph by Paracelsus). The term may be an original invention of Paracelsus, possibly deriving the term from Latin ''gēnomos'' (itself repres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isle Of Sheppey
The Isle of Sheppey is an island off the northern coast of Kent, England, neighbouring the Thames Estuary, centred from central London. It has an area of . The island forms part of the local government district of Swale. ''Sheppey'' is derived from Old English ''Sceapig'', meaning "Sheep Island". Today's island was historically known as the "Isles of Sheppey" which were Sheppey itself, the Isle of Harty to the south east and the Isle of Elmley to the south west. Over time the channels between the islands have silted up to make one contiguous island. Sheppey, like much of north Kent, is largely formed from London Clay and is a plentiful source of fossils. The Mount near Minster rises to above sea level and is the highest point on the island. The rest of Sheppey is low-lying and the southern part of the island is marshy land criss-crossed by inlets and drains, largely used for grazing. The economy is driven by a dockyard and port, the presence of three prisons, and various c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastchurch Airfield
Royal Air Force Eastchurch or more simply RAF Eastchurch (formerly RNAS Eastchurch) is a former Royal Air Force station near Eastchurch village, on the Isle of Sheppey, Kent, England. The history of aviation at Eastchurch stretches back to the first decade of the 20th century when it was used as an airfield by members of the Royal Aero Club. The area saw the first flight by a British pilot in Britain. In 1910 it was operated by the Royal Navy as a training aerodrome and it was known as the Naval Flying School, Eastchurch. In the 1910s the airfield was designated Royal Naval Air Station Eastchurch. With the amalgamation of the Royal Naval Air Service and the Royal Flying Corps on 1 April 1918, the station was transferred to the newly formed Royal Air Force and was re-designated Royal Air Force Eastchurch. Early civilian aviation The members of the Aero Club of Great Britain established their first flying ground near Leysdown on the Isle of Sheppey in 1909. One of the Club's m ...
