Cotswold Gliding Club
The Cotswold Gliding Club (CGC) is based at Aston Down airfield, between Cirencester and Stroud, Gloucestershire, Stroud in Gloucestershire, South West England. The club maintains a fleet of aircraft for training purposes, and is a centre for Gliding#Cross-country, cross-country gliding and Gliding competitions, competitions. Club CGC was formed in 1964. It was initially based at Long Newnton airfield near Tetbury, but in 1967 moved to its current home, Aston Down—at that time still a military airfield. In 1980-1, with the help of Sports Council grants and other loans, the club purchased a large part of the airfield when it was auctioned off by the Ministry of Defence (United Kingdom), Ministry of Defence. Having since acquired further land, CGC now owns most of the airfield within the perimeter track. CGC has some 200 members, including 80 students from the University of the West of England (UWE) in Bristol. There are about 30 associate members: these include both pilots ( ...

Aston Down
Aston Down is in Gloucestershire, South West England, east of Minchinhampton, southeast of Stroud and west of Cirencester. The nearest settlement is the large village of Chalford, 1 mile (1.6 km) to the northwest. The airfield was used by the Royal Air Force from the First World War until 1967 when the Cotswold Gliding Club moved in from their previous base near Tetbury. In 2002 the land and most of hangars surrounding the airfield were sold by the Ministry of Defence to private developers for use as industrial units. History First World War The airfield was originally opened as RAF Minchinhampton and was first used in the First World War, serving as an aerodrome for the Australian Flying Corps with No. 2 Squadron AFC flying the Royal Aircraft Factory S.E.5a and the Sopwith Pup and No. 3 Squadron AFC flying the Avro 504. The airfield closed shortly afterwards. Reopening In 1938 the airfield reopened under the new name of RAF Aston Down at the request of the resident ...

Land Yacht
Land sailing, also known as sand yachting, land yachting or dirtboating, is the act of moving across land in a wheeled vehicle powered by wind through the use of a sail. The term comes from analogy with (water) sailing. Historically, land sailing was used as a mode of transportation or recreation. Since the 1950s, it has evolved primarily into a racing sport. Vehicles used in sailing are known as sail wagons, sand yachts, or land yachts. They typically have three (sometimes four) wheels and function much like a sailboat, except that they are operated from a sitting or lying position and steered by pedals or hand levers. Land sailing works best in windy flat areas, and races often happen on beaches, airfields, and dry lake beds in desert regions. Modern land sailors, generally known as "pilots", can go three to four times faster than the wind speed. A gust of wind is considered more beneficial in a land sailing race than a favorable windshift. A similar sport, known as ice yachti ...

Schleicher ASK 23
The Schleicher ASK 23 is a single-seat Club Class sailplane that was built by the German manufacturer Alexander Schleicher GmbH & Co. Design The ASK 23 was the last glider to be designed by Rudolf Kaiser. It is an early-solo sailplane with docile handling, and was a successor to the Schleicher Ka 8 and ASK 18. It is also the single-seat counterpart of the two-seat Schleicher ASK 21 with a similar cockpit layout. It uses glass-fibre Fiberglass (American English) or fibreglass (Commonwealth English) is a common type of fiber-reinforced plastic using glass fiber. The fibers may be randomly arranged, flattened into a sheet called a chopped strand mat, or woven into glass clot ... reinforced plastic and 'honeycomb' as its main construction materials. It has no flaps, a nose wheel and a fixed main-wheel with a tail-skid or optional tail-wheel. First flown in October 1983, the initial version allowed for heavy pilots, with a maximum cockpit weight of , reduced to in the later AS ...

Schleicher ASK 13
The ASK 13 is a two-seater glider that was built by German sailplane manufacturer Alexander Schleicher Gmbh & Co. It was and still is widely used for basic training of glider pilots. Design and development In 1965 Rudolf Kaiser continued development of the two-seat Ka 2 and Schleicher Ka 7 by introducing the ASK 13, using a mixture of materials including metal, wood and glassfibre. It has swept-forward single-spar wings, positioned lower than in the Ka 7, which allows for a large blown canopy providing a good all-round view for both pilots. The 6 degree forward sweep of the wing allows the rear pilot to be seated near the centres of gravity and lift. The glider therefore maintains the same trim whether flown single seated or dual seated. The D-type leading edge torsion box is of plywood and the whole wing is fabric-covered. There are metal Schempp-Hirth air brakes above and below the wing, and the wooden ailerons are fabric-covered. The fuselage is a welded steel tube str ...

Glaser-Dirks DG-500
The Glaser-Dirks DG-500, and later the DG-505, is a two-seat glider of glass-reinforced plastic and carbon fiber reinforced plastic construction, manufactured in the DG Flugzeugbau GmbH in Bruchsal, Germany. It first flew in 1987. Design The glider is a trainer with an 18-metre wingspan or a high-performance glider with 20 or 22 m span. There are also trailing edge flaps with the exception of the Trainer and Orion variants. The 20m version also has winglets. The fuselage has a single wheel main landing gear which retracts into the lower fuselage. The DG-500/18 is mainly intended for flight training, and is fully aerobatic with +7/-5 g rating. There is also a motorglider version, the DG-500M. The DG-500/22 can carry up to 160 kg of water ballast which is not possible on the trainer version. Since 2004, the latest version of the DG-500 has been built as the "DG-505 Orion" in Slovenia. Past altitude record The DG-500 once held the all-time altitude record for manned glide ...

Schleicher ASK 21
The ASK 21 is a glass-reinforced plastic (GRP) two-seat glider aircraft with a T-tail. The ASK 21 is designed primarily for beginner instruction, but is also suitable for cross-country flying and aerobatic instruction. Design and development The ASK 21 was designed by Rudolf Kaiser to replace the popular ASK 13, providing a modern two-seat aircraft bridging the gap between initial training and single-seat performance flying. The ASK 21 is the first full-GRP two-seater produced by Schleicher, flying for the first time in February 1979 (6.2.1979). Production also began in 1979, remaining in production to this day (May 2018), over 900 units completed. In December 2004 the ASK 21 Mi, a self-launching version, made its first flight. In 2003 the operating time was extended to 18,000 hours A revised and improved version, the ASK 21B was introduced in 2018. Construction The two seats are in a tandem arrangement with dual controls, adjustable rudder pedals and seatbacks. The fuselage c ...

Perspective (graphical)
Linear or point-projection perspective (from la, perspicere 'to see through') is one of two types of 3D projection, graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper. The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to ''foreshortening'', meaning that an object's dimensions along the line of sight appear shorter than its dimensions across the line of sight. All objects will recede to points in the distance, usually along the horizon line, but also above and below the horizon line depending on the view used.

Webcam
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in videotelephony, livestreaming and social media, and security. Webcams can be built-in computer hardware or peripheral devices, and are commonly connected to a device using USB or wireless protocols. Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers also started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people working from home. History Early development (early 1990s) First developed in 1991, a webcam was pointed at the Trojan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Competitions
Competition is a rivalry where two or more parties strive for a common goal which cannot be shared: where one's gain is the other's loss (an example of which is a zero-sum game). Competition can arise between entities such as organisms, individuals, economic and social groups, etc. The rivalry can be over attainment of any exclusive goal, including recognition: Competition occurs in nature, between living organisms which co-exist in the same environment. Animals compete over water supplies, food, mates, and other biological resources. Humans usually compete for food and mates, though when these needs are met deep rivalries often arise over the pursuit of wealth, power, prestige, and fame when in a static, repetitive, or unchanging environment. Competition is a major tenet of market economies and business, often associated with business competition as companies are in competition with at least one other firm over the same group of customers. Competition inside a company is usu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
