De Havilland DH.52
The de Havilland DH.52 was a single-seat, high-winged glider produced as an entrant to a 1922 prize competition. Two were built but insufficient torsional stiffness in the wings led to control problems and the DH.52 was rapidly abandoned. Development The DH.52 was de Havilland's only glider, built to compete for the prize in the ''Daily Mail'' Gliding Competition, held at Itford, Sussex in 1922. It was a high-wing monoplane with an aspect ratio of 11.4; the wing was wire braced, with pairs of wires from the keel to the front and rear wing spars at about ⅓ and ¾ span. Similar pairs of wires to a central king post supported the weight of the wings and kept the bracing in tension. The kingpost consisted of two members, one from each wing spar at the centre line, meeting about above the wing. The resulting triangular structure appears to have been covered with cambric Cambric or batiste is a fine dense cloth. It is a lightweight plain-weave fabric, originally from the ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling 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 Magazine, 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".

Sussex
Sussex (Help:IPA/English, /ˈsʌsɪks/; from the Old English ''Sūþseaxe''; lit. 'South Saxons'; 'Sussex') is an area within South East England that was historically a kingdom of Sussex, kingdom and, later, a Historic counties of England, county. It includes the Ceremonial counties of England, ceremonial counties of East Sussex and West Sussex. The area borders the English Channel to the south, and the Ceremonial counties of England, ceremonial counties of Surrey to the north, Kent to the north-east, and Hampshire to the west. Sussex contains the city of Brighton and Hove and its wider Greater Brighton City Region, city region, as well as the South Downs National Park and the National Landscapes of the High Weald National Landscape, High Weald and Chichester Harbour. Its coastline is long. The Kingdom of Sussex emerged in the fifth century in the area that had previously been inhabited by the Regni tribe in the Roman Britain, Romano-British period. In about 827, shortly a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aspect Ratio
The aspect ratio of a geometry, geometric shape is the ratio of its sizes in different dimensions. For example, the aspect ratio of a rectangle is the ratio of its longer side to its shorter side—the ratio of width to height, when the rectangle is oriented as a "landscape format, landscape". The aspect ratio is most often expressed as two integer numbers separated by a colon (x:y), less commonly as a simple or decimal Fraction (mathematics), fraction. The values x and y do not represent actual widths and heights but, rather, the proportion between width and height. As an example, 8:5, 16:10, 1.6:1, and 1.6 are all ways of representing the same aspect ratio. In objects of more than two dimensions, such as hyperrectangles, the aspect ratio can still be defined as the ratio of the longest side to the shortest side. Applications and uses The term is most commonly used with reference to: * Graphic / image ** Aspect ratio (image), Image aspect ratio ** Display aspect ratio ** Pape ...

Cambric
Cambric or batiste is a fine dense cloth. It is a lightweight plain-weave fabric, originally from the commune of Cambrai (in present-day northern France), woven greige (neither bleached nor dyed), then bleached, piece-dyed, and often glazed or calendered. Initially it was made of linen; from the 18th and 19th centuries the term came to apply to cotton fabrics as well. Chambray is a similar fabric, with a coloured (often blue or grey) warp and white filling; the name "chambray" replaced "cambric" in the United States in the early 19th century. Cambric is used as fabric for linens, shirts, handkerchiefs, ruffs, lace, and in cutwork and other needlework. Dyed black, it is also commonly used as the dustcover on the underside of upholstered furniture. Description Cambric is a finely woven cloth with a plain weave and a smooth surface appearance, the result of the calendering process. It may be made of linen or cotton. The fabric may be dyed any of many colours. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RAF 15
The Royal Air Force (RAF) is the air and space force of the United Kingdom, British Overseas Territories and Crown Dependencies. It was formed towards the end of the First World War on 1 April 1918, on the merger of the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has played a significant role in British military history. In particular, during the Second World War, the RAF established air superiority over Nazi Germany's Luftwaffe during the Battle of Britain, and led the Allied strategic bombing effort. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives ...

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 gliding flight, 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 Motor glider, 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 lift (soaring), 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 a ...
