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 either ...

EASA
The European Union Aviation Safety Agency (EASA) is an agency of the European Union (EU) with responsibility for civil aviation safety. It carries out certification, regulation and standardisation and also performs investigation and monitoring. It collects and analyses safety data, drafts and advises on safety legislation and co-ordinates with similar organisations in other parts of the world. The idea of a European-level aviation safety authority goes back to 1996, but the agency was legally established only in 2002; it began its work in 2003. History Based in Cologne, Germany, the agency was created on 15 July 2002 as the "European Aviation Safety Agency", and reached full functionality in 2008, taking over functions of the Joint Aviation Authorities. It was renamed the "European Union Aviation Safety Agency" in 2018. European Free Trade Association countries participate in the agency. The United Kingdom was a member until the end of the Brexit transition period on 31 Dec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-tail Aircraft
A T-tail is an empennage wikt:configuration, configuration in which the tailplane is mounted to the top of the vertical stabilizer, fin. The arrangement looks like the capital letter T, hence the name. The T-tail differs from the standard configuration in which the tailplane is mounted to the fuselage at the base of the fin. Advantages T-tails were common in early jet aircraft. Designers were worried that an engine failure would otherwise damage the horizontal tail. The T-tail is very common on aircraft with engines mounted in nacelles on a Wing_configuration#Number_and_position_of_main_planes, high-winged aircraft or on aircraft with the engines mounted on the rear of the fuselage, as it keeps the tail clear of the jet exhaust. Rear-mounting the engines keeps the wings clean and improves short-field performance. This was necessary in early jet aircraft with less powerful engines. T-tail aircraft can have better short-field performance, such as on the British Aerospace ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2000s South African Sailplanes
S, or s, is the nineteenth letter in the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''ess'' (pronounced ), plural ''esses''. History Origin Northwest Semitic šîn represented a voiceless postalveolar fricative (as in 'ip'). It originated most likely as a pictogram of a tooth () and represented the phoneme via the acrophonic principle. Ancient Greek did not have a phoneme, so the derived Greek letter sigma () came to represent the voiceless alveolar sibilant . While the letter shape Σ continues Phoenician ''šîn'', its name ''sigma'' is taken from the letter ''samekh'', while the shape and position of ''samekh'' but name of ''šîn'' is continued in the '' xi''. Within Greek, the name of ''sigma'' was influenced by its association with the Greek word (earlier ) "to hiss". The original name of the letter "sigma" may have been ''san'', but due to the complic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

It is in 4 pieces, each tip is 1.5 metres. Two novel features are: * a double-hole blowing/suction system in the wings to minimise drag. The two rows of blow holes on the lower surface prevent turbulent flow at specific locations for different flap settings, thus reducing drag * a jet engine for the self-sustaining version. A self-launching version was considered but it was decided that the fusela ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Gliding Championships
The World Gliding Championships (WGC) is a gliding competition held every two years or so by the FAI Gliding Commission. The dates are not always exactly two years apart, often because the contests are sometimes held in the summer in the Southern Hemisphere. History Gliding had been a demonstration sport at the 1936 Summer Olympics and was due to become an official Olympic sport in the Helsinki Games in 1940. However, since the Second World War, gliding has not featured in the Olympics, and so the World Championships are the highest level in the sport. There are now contests for six classes of glider and so in recent years the Championships have been divided between two locations. The women's, junior, grand prix and aerobatic events are also held separately. Each of the following entries give the year and location of the contest followed by the winner of each class, nationality and the glider used.

Type Certification
A type certificate signifies the airworthiness of a particular category of aircraft, according to its manufacturing design (''type design''). It confirms that the aircraft of a new type intended for serial production, is in compliance with applicable airworthiness requirements established by the national air law. For up to three seats, primary category aircraft, certification costs around US$1m, US$25m for a general aviation aircraft and hundreds of millions of dollars for a commercial aircraft; certification delays can cost millions of dollars and can decide a program's profitability. Authority A type certificate (TC) is issued to signify the airworthiness of the approved design or "type" of an aircraft to be manufactured. The TC is issued by a regulatory authority, and once issued, the design cannot be changed unless at least part of the process for certification is repeated to cover the changes. The TC reflects a determination made by a regulatory authority that the type desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
