Schleicher ASW 22
The ASW 22 is an Open Class glider built by Alexander Schleicher GmbH & Co which first flew in 1981. The 'W' in the designation indicates that this is a product of the German designer Gerhard Waibel. An ASW 22 broke the world 750 km triangle speed record in 1985 and ASW 22s have won first place in six World Gliding Championships. Design The ASW 22 is the successor to the ASW 17. It first flew as a 22-metre glider. The span was later increased to 25 metres for the ASW 22B with a modified inner wing section and flaperons similar to the ASW 20. It uses a Horstmann and Quast wing profile on the inner section with underwing tubes to collect high-pressure air which is then expelled through turbulator holes in the bottom wing skin ahead of the flap and aileron hinge line to prevent the separation of the laminar flow. The ASW 22 has a two-wheel retractable undercarriage. Variants ;ASW 22:Open Class high-performance sailplane; 22 or 24 metre span ;ASW 22M:First motorized self ...

A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".

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 It was superseded in production by the ASH 30.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 The Wankel engine (, ) is a type of internal combustion engine using an eccentric (mechanism), eccentric Pistonless rotary engine, rotary design to convert pressure into rotating motion. The concept was proven by German engineer Felix Wankel, ...

T-tail Aircraft
A T-tail is an empennage configuration in which the tailplane of an aircraft is mounted to the top of the 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 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 Avro RJ-85. The disturbed airflow over a lower stabilizer can make control more difficult at lowe ...

1980s German Sailplanes
__NOTOC__ Year 198 (CXCVIII) was a common year starting on Sunday of the Julian calendar. At the time, it was known as the Year of the Consulship of Sergius and Gallus (or, less frequently, year 951 ''Ab urbe condita''). The denomination 198 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Schempp-Hirth Nimbus 4
The Schempp-Hirth Nimbus-4 is a family of high-performance FAI Open Class gliders designed by Klaus Holighaus and manufactured by Schempp-Hirth Flugzeugbau GmbH in Kirchheim, Germany. The Nimbus-4 first flew in 1990. Design and development The Nimbus-4 family is a direct derivative of its predecessors at the highest performance end of the Schempp-Hirth product range, the Nimbus-2 and Nimbus-3. In total , 44 single-seat and 100 two-seat models have been produced. The wing taper varies along the span, which is increased to 26.5 metres. The aspect ratio is 38.8. The fuselage is also lengthened and a larger rudder fitted. The manufacturer claims this glider has a glide ratio of better than 60:1 at a best glide airspeed of 110 km/h (59 knots), meaning it can glide over 60 kilometres on course for every 1000 metres of altitude lost in still air. There is a two-seat version, the 4D, and motor glider versions with either turbo engines (designation T) or self-launching engi ...

Eta (glider)
The Eta is a German-Italian Open Class two-seater flapped self-launching glider manufactured by ETA Aircraft. On introduction it was the highest performing glider. Early flights The Eta made its first flight on July 31, 2000 in Cochstedt, Germany, reaching a height of . The second flight was the first aerotow launch, reaching . The third flight was self powered and had no problems. The official presentation was on 1 August. Production Three Etas have been manufactured. The second prototype was extensively damaged in 2003 during the spin tests required for the type certification but both pilots parachuted to safety. The prototype was repaired and the tests completed successfully. The glider was to be produced by hand at a rate of about three per year. Development The Eta is an example of a trend in glider development in which private pilots initiate the development of new open class gliders. The private development of the Concordia sailplane promises a further elevation ...
