Slingsby T.20
The Slingsby T.20 was a British glider designed and built by Slingsby that first flew in 1944.Simons, Martin. ''Slingsby Sailplanes''. Shrewsbury: Airlife, 1996. . Design and development The Type 20 was probably the least well known Slingsby product, yet it arguably had the most exciting flying life. The design started life in parallel with the larger Type 21, as a private venture inexpensive robust two-seat training glider intended for the Air Training Corps. The aircraft borrowed design elements from several predecessors, including an enlarged wing from the T.8 Kirby Tutor, and a fuselage, reminiscent of the early Falcons, with cabane struts in front of the rear cockpit, which sat in front of the narrow cabane structure under the centre-section, as well as an additional cockpit in the nose. Flight trials Flying with the T.20 began in 1944 with no reported problems, the prototype languished at Sutton Bank Gliding Club, emerging only to fly the occasional illegal soaring flig ...

Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Slingsby Aviation
Slingsby Aviation was a British aircraft manufacturer based in Kirkbymoorside, North Yorkshire, England. The company was founded to design and build gliders and sailplanes. From the early 1930s to around 1970 it built over 50% of all British club gliders and had success at national and international level competitions. It then produced some powered aircraft, notably the composite built Firefly trainer, before becoming a producer of specialised composite materials and components. The business is now known as Marshall Advanced Composites and produces composite parts for ships, submarines and aircraft. It is a subsidiary of Marshall of Cambridge. History The business was founded in Scarborough by Frederick Nicholas Slingsby, an RAF pilot in World War I. In 1920 he bought a partnership in a woodworking and furniture factory in Queen Street, Scarborough. In 1930 Slingsby was one of the founders of the Scarborough Gliding Club. After repairing some of the club's gliders, Sling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Training Corps
The Air Training Corps (ATC) is a British volunteer-military youth organisation. They are sponsored by the Ministry of Defence and the Royal Air Force. The majority of staff are volunteers, and some are paid for full-time work – including Commandant Air Cadets, a Full Term Reserve Service RAF officer. In 2013, the officer in command of the ATC was Air Commodore Dawn McCafferty. Although many ATC cadets go on to join the RAF or other services, the ATC is not a recruiting organisation for its parent service. Activities include sport, adventure training (such as walking and paddle-sports), ceremonial drill, rifle shooting, field craft, powered aircraft, glider flying, and other outdoor activities, as well as classification training leading up to a BTEC in Aviation Studies. Week-long trips to RAF stations, or camps offering adventure training or music, allow the opportunity for cadets to gain a taste of military life and often some flying experience in RAF gliders and RAF tra ...

Flight Deck
The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships". Flight decks have been in use upon ships since 1910, the American pilot Eugene Ely being the first individual to take off from a warship. Initially consisting of wooden ramps built over the forecastle of capital ships, a number of battlecruisers, including the British and , the American and , and the Japanese Akagi and battleship Kaga, were converted to aircraft carriers during the interwar period. The first aircraft carrier to feature a full-length flight deck, akin to the configuration of the modern vessels, was the converted liner . The armoured flight deck was another innovation pioneered by the Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flaps (aircraft)
A flap is a high-lift device used to reduce the stalling speed of an aircraft wing at a given weight. Flaps are usually mounted on the wing trailing edges of a fixed-wing aircraft. Flaps are used to reduce the take-off distance and the landing distance. Flaps also cause an increase in drag so they are retracted when not needed. The flaps installed on most aircraft are partial-span flaps; spanwise from near the wing root to the inboard end of the ailerons. When partial-span flaps are extended they alter the spanwise lift distribution on the wing by causing the inboard half of the wing to supply an increased proportion of the lift, and the outboard half to supply a reduced proportion of the lift. Reducing the proportion of the lift supplied by the outboard half of the wing is accompanied by a reduction in the angle of attack on the outboard half. This is beneficial because it increases the margin above the stall of the outboard half, maintaining aileron effectiveness and reduci ...

HMS Pretoria Castle (F61)
HMS ''Pretoria Castle'' (F61) was a Union-Castle ocean liner that in the Second World War was converted into a Royal Navy armed merchant cruiser, and then converted again into an escort carrier. After the war she was converted back into a passenger liner and renamed ''Warwick Castle''. History Harland and Wolff built ''Pretoria Castle'' in Belfast, launching her in 1938 and completing her in April 1939. The Admiralty requisitioned her for the Royal Navy in October 1939, and had her converted into an armed merchant cruiser with eight and two guns, entering service in November 1939. In this role she served mainly in the South Atlantic. In July 1942 the Admiralty bought her outright for conversion to an escort carrier by Swan Hunter on Tyneside. For her new role her armament included ten Oerlikon 20 mm cannon. She was commissioned in her new role in July 1943. She operated as a trials and training carrier, seeing no active combat service. In 1945 she twice became part of av ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Clyde
The River Clyde ( gd, Abhainn Chluaidh, , sco, Clyde Watter, or ) is a river that flows into the Firth of Clyde in Scotland. It is the ninth-longest river in the United Kingdom, and the third-longest in Scotland. It runs through the major city of Glasgow. Historically, it was important to the British Empire because of its role in shipbuilding and trade. To the Romans, it was , and in the early medieval Cumbric language, it was known as or . It was central to the Kingdom of Strathclyde (). Etymology The exact etymology of the river's name is unclear, though it is known that the name is ancient: It was called or by the Britons and by the Romans. It is therefore likely that the name comes from a Celtic language—most likely Old British. But there is more than one old Celtic word that the river's name could plausibly derive from. One possible root is the Common Brittonic , meaning 'loud' or 'loudly'. More likely, the river was named after a local Celtic goddess, '' Clōta ...

NACA Airfoil
The NACA airfoils are airfoil shapes for aircraft wings developed by the National Advisory Committee for Aeronautics (NACA). The shape of the NACA airfoils is described using a series of digits following the word "NACA". The parameters in the numerical code can be entered into equations to precisely generate the cross-section of the airfoil and calculate its properties. Origins NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center. According to the NASA website: Four-digit series The NACA four-digit wing sections define the profile by: # First digit describing maximum camber as percentage of the chord. # Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord. # Last two digits describing maximum thickness of the airfoil as percent of the chord. For example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slingsby Falcon
The Slingsby T.1/T.2 Falcon or British Falcon) was a single-seat sport glider produced, in 1931–37, by Fred Slingsby in Scarborough, Yorkshire. Design and development The Falcon was constructed from plans supplied by the Rhön-Rossitten Gesellschaft (the controlling body for gliding in Germany). Originally designed by Alexander Lippisch, the T.1 was a single-seat sport glider of moderate performance for its day. The fuselage was primarily of wooden construction with six longerons, built-up frames, plywood skinning forward of the central pylon and fabric covering aft. The parasol wings were conventional in design and construction with built-up ribs and spars, plywood covering forward of the main spars and fabric aft. They were swept at 12.5o but carried ailerons with unswept hinges and rounded trailing edges. The wings were built in two parts joined at the centre, supported by a pylon and a total of eight struts, four vertical from the top longerons and four in vee pairs from ...

Slingsby Tandem Tutor
The T.31 Tandem Tutor is a British military training glider, designed and built by Slingsby and used in large numbers by the Air Training Corps between 1951 and 1986. Design and development The T.31 was a tandem two-seat development of the T.8 Tutor (RAF Cadet TX.2). The fuselage was based on that of the T.29 Motor Tutor, increased in length and widened slightly; the wings and tail were unchanged. A single T.31A prototype was flown in 1949, followed by the production T.31B, with spoilers and a small additional wing bracing strut. Operational history Chief customer for the T.31B was the Royal Air Force for Air Cadet training; its aircraft were designated as Cadet TX Mark 3. As it was so similar to their existing single-seaters, it allowed easy conversion to solo. The RAF took delivery of 126 TX.3s between 1951 and 1959. It also found a market with civilian clubs in the UK, although most of these were built from kits and spares, using existing Tutor wings. T.31s were exported ...
