Glider Competition Classes
Competition classes in gliding, as in other sports, mainly exist to ensure fairness in competition. However the classes have not been targeted at fostering technological development as in other sports. Instead classes have arisen because of: * the popularity of certain types of glider * attempts to contain the cost of access to the sport * the need to establish a stable environment for investment decisions by both manufacturers and competitors. The FAI Gliding Commission (IGC) is the sporting body overseeing air sports at the international level so that essentially the same classes and class definitions are followed in all countries. FAI Competition Classes Seven glider classes are currently recognised by the FAI and are eligible for European and World Championships: * Open Class, places no restrictions except a limit of 850 kg to the maximum all-up mass, may be one- or two-seater e.g. JS-1C, Lange Antares 23E, Quintus, ASW 22, ASH 30, LAK-20. * Standard Class, restri ...

Alexander Schleicher GmbH & Co
Alexander Schleicher GmbH & Co is a major manufacturer of sailplanes located in Poppenhausen, near Fulda in Germany. It is also the oldest sailplane manufacturer in the world. History The company was founded in 1927 by Alexander Schleicher using money that he had won as a pilot in a gliding competition. It grew quickly in size and fame, producing many notable designs including the ''Anfänger ("Beginner")'', ''Zögling ("Student")'', ''Professor'', ''Mannheim'', and the ''Stadt Frankfurt (City of Frankfurt)''. Meanwhile, the aircraft produced under contract by the company continued to grow in size and complexity, reaching their pinnacle with the ''DFS Rhönadler (Rhön eagle)'' and '' DFS Rhönbussard (Rhön buzzard)'' designed by Hans Jacobs, and a huge, three-seat experimental glider built from a design by Alexander Lippisch for the ''Deutsche Forschungsanstalt für Segelflug'' (DFS - German Research Institute for Sailplane Flight).

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 ...

Schleicher ASH 25
The ASH 25 is a two-seater high performance Open Class glider manufactured by Alexander Schleicher from 1986 until September 2008, originally with a 25-metre wingspan. It was superseded in production by the ASH 30. Design and development In 1984, designer Martin Heide (the 'H' in the type designation) combined the wing of the World Championship winning single-seater Schleicher ASW 22 with a fuselage derived from the Akaflieg Stuttgart fs31 which had particularly low drag. The prototype was designated AS 22-2. The span was increased in later versions to 25.6 or 26 metres with winglets. A 'turbo' version was also developed, the ASH 25E, followed by the self-launching ASH 25 Mi with a large retractable propeller and a Wankel engine. Variants ;ASH 25:A 25m Open class glider, 25.6m or 26m wingspan when fitted with option winglets. ;ASH 25E:Self-sustaining version with a 24 hp Rotax 275 The Rotax 275 is a , single-cylinder, two-stroke aircraft engine, built by BRP-Ro ...

Wankel Engine
The Wankel engine (, ) is a type of internal combustion engine using an Eccentric (mechanism), eccentric rotary combustion engine, rotary design to convert pressure into rotating motion. It was invented by German engineer Felix Wankel, and designed by German engineer Hanns-Dieter Paschke. The Wankel engine's rotor, which creates the turning motion, is similar in shape to a Reuleaux triangle, with the sides having less curvature. The rotor rotates inside an oval-like epitrochoidal housing, around a central output shaft. The rotor spins in a hula-hoop fashion around the central output shaft, spinning the shaft via toothed gearing. Due to its inherent poor thermodynamics, the Wankel engine has a significantly worse thermal efficiency and worse exhaust gas behaviour when compared against the Otto engine or the Diesel engine, which is why the Wankel engine has seen limited use since its introduction in the 1960s. However, its advantages of compact design, smoothness, lower weight and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wasserkuppe
The is a mountain within the German state of Hesse. It is a large plateau formation at an elevation of and is the highest peak in the Rhön Mountains. Great advances in sailplane development took place on the mountain during the interwar period, driven by annual contests. Near the summit there is still an airfield used by gliding clubs and pilots of light aircraft. Etymology The German name is derived from ''Wasenkuppe, Asenberg'' or ''Weideberg'' and means ''Pasture mountain''. Geography The Wasserkuppe lies in the administrative district Fulda north of Gersfeld. Other villages nearby are Poppenhausen ( west - south west) and Wüstensachsen ( east, part of Ehrenberg, Hesse). It is part of the Rhön Biosphere Reserve. The Wasserkuppe sources the spring of the river Fulda (the western source of the Weser) and the river Lütter which joins the Fulda after . The other peaks near the Wasserkuppe are Abtsrodaer Kuppe (north, NN), (east, NN) and Pferdskopf (so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

2010s German Sailplanes
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
