EoN Type 10 Eon 463
The EoN 460 series are wooden single-seat standard class sailplanes, built in the UK in the 1960s. It did not have major competition success but some remain in use in 2021. Design and development It was built in 1961 as a completely new Standard Class glider. The name Eon 460, sometimes written as Eon Olympia 460, stands both for a series of gliders and for the prototypes of the series, all described by EoN as Type 10. Five slightly different model 460 prototypes were followed by 48 production model 463s. Two model 465s, with slimmer, slightly longer fuselages made possible by a semi-reclining pilot's position, were built for the 1965 World Gliding Championships. They were the last gliders designed and built by Elliotts of Newbury before their takeover by Slingsby Sailplanes in March 1966. All the 460 series have wooden structures and are largely plywood skinned. They have straight-tapered cantilever shoulder wings with 5° of dihedral and fabric covering over the plywo ...

A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

RAF Tibenham
Royal Air Force Tibenham or more simply RAF Tibenham is a former Royal Air Force station located southwest of Norwich and north of Diss, Norfolk, England. History Tibenham was used as a Royal Flying Corps landing ground during the First World War and was known as RFC Tibenham. No. 51 Squadron RFC and 75 Sqn RFC allegedly used the landing ground. USAAF use The airfield was built up during 1941/42 as a standard heavy bomber airfield with a main runway (03-21) and two secondary runways in length (08-26, 15-33). It had an enclosed perimeter track containing 36 frying-pan type hardstands and fourteen loops. Two T-2 hangars were constructed on the eastern side of the airfield and adjacent to the technical site. Accommodations were constructed for about 2,900 personnel. Tibenham was assigned USAAF designation Station 124. 320th Bombardment Group (Medium) The first American units at Tibenham were the personnel of two Martin B-26 Marauder squadrons of the Twelfth Air Force 32 ...

Vintage Glider Club
Vintage, in winemaking, is the process of picking grapes and creating the finished product—wine (see Harvest (wine)). A vintage wine is one made from grapes that were all, or primarily, grown and harvested in a single specified year. In certain wines, it can denote quality, as in Port wine, where Port houses make and declare vintage Port in their best years. From this tradition, a common, though not strictly correct, usage applies the term to any wine that is perceived to be particularly old or of a particularly high quality. Most countries allow a vintage wine to include a portion of wine that is not from the year denoted on the label. In Chile and South Africa, the requirement is 75% same-year content for vintage-dated wine. In Australia, New Zealand, and the member states of the European Union, the requirement is 85%. In the United States, the requirement is 85%, unless the wine is designated with an AVA, (e.g., Napa Valley), in which case it is 95%. Technically, the 85% r ...

Royal Air Force Gliding & Soaring Association
The Royal Air Force Gliding & Soaring Association is a British organisation which provides recreational flying in gliders to RAF personnel. Purpose The Royal Air Force Gliding & Soaring Association (RAFGSA) is a voluntary organisation which exists to provide recreational flying to all RAF servicemen and women, in particular those normally employed in ground duties. The RAFGSA Centre is at RAF Halton, employing a full-time staff to provide central organisational, training and workshop facilities. The Joint Services Gliding Centre (JSGC), located at the RAFGSA Chilterns Centre, RAF Halton, is part of the Joint Service Adventurous Training (JSAT) Air Sports organisation and provides training courses for military personnel. History In 1945, the British Air Forces of Occupation (BAFO) in Germany began using captured German gliders to provide recreational flying for RAF personnel. This resulted in a demand for similar facilities in the United Kingdom, and the Royal Air Force Glidi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Cerney
South Cerney is a village and civil parish in the Cotswold district of Gloucestershire, 3 miles south of Cirencester and close to the border with Wiltshire. It had a population of 3,074 according to the 2001 census, increasing to 3,464 at the 2011 census. It was founded in 999 by Saxon settlers, with a charter by King Aethelred II. In 2001 South Cerney was winner of the Bledisloe Cup for the best-kept village in Gloucestershire (large village class), having previously won the award in 1955. Church of All Hallows, South Cerney and Ann Edwards School Two fragments of a carved wooden crucified Christ, a head and a foot, were found in 1915 concealed in a wall of the village church. The crucifix was probably hidden at the time of the Reformation but mostly disintegrated due to the damp. Part of a crucifix that dates from the 12th century, it is one of very few early-medieval wooden sculptures of Christ extant in England, and would have been part of the 'rood' that stood above t ...

RAF Odiham
RAF Odiham is a Royal Air Force station situated a little to the south of the village of Odiham in Hampshire, England. It is the home of the Royal Air Force's heavy lift helicopter, the Chinook, and of the King’s Helicopter Flight (TKHF) . Its current station commander is Group Captain Donal McGurk. History Aircraft operations began from the site in 1925 but it was not until October 1937 that it was opened as a permanent airfield. Second World War During the Second World War North American Mustangs and Hawker Typhoons were flown out of the base. After the Allied invasion of Europe the site became a prisoner of war camp. * No. 2 Squadron RAF operated the Mustang I between 7 August 1943 and 22 September 1943 and again between 6 October 1943 and 14 November 1943. ** The squadron returned on 27 June 1944 with the Mustang II before leaving on 29 July 1944. * No. 4 Squadron RAF using the Hawker Hector and the Westland Lysander I between 16 February 1936 and 24 September 1939. ...

RAE Bedford
RAE Bedford was a research site of the Royal Aircraft Establishment between 1946 and 1994. It was located near the village of Thurleigh, north of the town of Bedford in England and was the site of aircraft experimental development work. In the book ''"A Short Illustrated History of the Royal Aircraft Establishment, Bedford"'', author Arthur Pearcy writes: ''"(RAE Bedford is) the finest research and development establishment outside the U.S.A."'' Starting in 1946, construction work began to turn the wartime RAF airfield into what became known as the Royal Aeronautical Establishment, Bedford. The runway was extended in the post-war period to accommodate the Bristol Brabazon aircraft, which required a very long runway but which never went into production. A lot of the development for what became the Harrier was done here, one early version became known as the 'Flying Bedstead'. Also Thurleigh had a catapult runway and it was here that the 'ski jump' later fitted to some airc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Gear
Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin Company. For aircraft, Stinton makes the terminology distinction ''undercarriage (British) = landing gear (US)''. For aircraft, the landing gear supports the craft when it is not flying, allowing it to take off, land, and taxi without damage. Wheeled landing gear is the most common, with skis or floats needed to operate from snow/ice/water and skids for vertical operation on land. Faster aircraft have retractable undercarriages, which fold away during flight to reduce drag. Some unusual landing gear have been evaluated experimentally. These include: no landing gear (to save weight), made possible by operating from a catapult cradle and flexible landing deck: air cushion (to enable operation over a wide range of ground obstacles and wat ...

Monowheel
A monowheel, or uniwheel, is a one-wheeled single-track vehicle similar to a unicycle. Hand-cranked and pedal-powered monowheels were patented and built in the late 19th century; most built in the 20th and 21st century have been motorized. Some modern builders refer to these vehicles as monocycles, though that term is also sometimes used to describe motorized unicycles. The world speed record for a motorized monowheel is 98.464 km/h (61.18 mph). Stability Similar to bicycles, monowheels are stable in the direction of travel, but have limited horizontal stability. This is in contrast to unicycles which are unstable in both directions. Monowheels have also been found to have a lower speed required for stability when compared to unicycles. A monowheel remains upright due to gyroscopic effects, but its lack of stability makes it highly dependent on forward momentum and the balance of the rider, who must maintain stability while steering. Over the history of the mono ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
