LS10
The Rolladen-Schneider LS10 is an 18 metre sailplane designed in Germany by Rolladen-Schneider. A prototype flew in 2003. After Rolladen-Schneider was placed in receivership the sailplane entered production by DG Flugzeugbau. Certification was not achieved until 2010. Other gliders were designed and manufactured by competitors during this period and were produced in greater numbers. Design and development By the mid-nineties Rolladen-Schneider, prompted by customers, began designing a successor to the LS6. Development was protracted, as the LS8 and LS9 projects had higher priority and the company's owner, Walter Schneider, felt the LS6 was still competitive. The initial design was made under the direction of Wolf Lemke. Werner Scholz then developed the prototype, the LS10-a. Although early 3-view drawings of the LS10 showed a curved canopy rail similar to that of the Schleicher ASW 24, when the prototype was revealed it had the same straight canopy rail as the LS6 and LS ...

Rolladen-Schneider LS6
The Rolladen-Schneider LS6 is a 15 metre and 18 metre single-seat flapped glider manufactured by Rolladen-Schneider Flugzeugbau GmbH between 1984 and 2003. Development The prototype of the LS6, successor to the LS3 in the FAI 15 metre Class, made its first flight in 1983. Having entered production one year later, the LS6 had an uncommonly long production run ended by Rolladen-Schneider's entry into receivership in 2003. A total of 375 of all versions were built. A watershed design, the LS6 introduced carbon reinforced plastic as a structural material in LS-gliders, thin profiles for wings and empennage, wing extensions and other features that have been retained in all subsequent types developed by the company. The Akaflieg Darmstadt D41, the LS9 and the Akaflieg Köln LS11 all have wings built in the LS6 moulds. Bettering the record of the LS4 in the Standard Class, the LS6 dominated the 15 metre Class over nearly a decade, winning the first two places at the 1985 Wo ...

FAI 18 Metre Class
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 ASW 28
The ASW 28 is a Standard Class glider with a fifteen-metre span built of modern fibre reinforced composites. The manufacturer of the ASW-28 is Alexander Schleicher GmbH & Co. The 'W' indicates this is a design of the influential and prolific German designer Gerhard Waibel. Serial production started in 2000. Design and development The ASW 28 is a single-seat shoulder-winged composite construction sailplane with a T-shaped horizontal tailplane and 15 metre wingspan. The upper wing surface has Schempp-Hirth airbrakes. As all Standard Class sailplanes, the ASW-28 does not have flaps or other lift-enhancing devices. It has tall winglets, a retractable undercarriage and a water ballast system. The structure is a complex composite of carbon, aramid and polyethylene fibre reinforced plastic. This permits a light structure with the strength to carry large amounts of water ballast, thus permitting the widest possible range of wing loadings for weak and strong soaring weather. The A ...

Schempp-Hirth Discus-2
The Schempp-Hirth Discus-2 is a Standard Class sailplane produced by Schempp-Hirth since 1998. It replaced the highly successful Schempp-Hirth Discus. Design and development In plan view the almost crescent shape of the leading edge is similar to the Discus but is tapered in three stages. An entirely new wing section is used. The dihedral towards the tips was greatly increased compared with the Discus. Winglets are an optional extra. A version with a narrow fuselage is called the Discus-2a and the wider fuselage version is called the 2b. The fuselage was specifically designed to be highly crash resistant. In U.S. Air Force service the Discus-2b is known as the TG-15B. The Discus-2 has also been successful though the competition from the Rolladen-Schneider LS8 and the Alexander Schleicher ASW 28 has meant that the Discus-2 has not sold in such great numbers as its predecessor, which went unchallenged for many years. 18 metre version A version with an 18-metre span, with th ...

Schempp-Hirth
Schempp-Hirth Flugzeugbau GmbH is a glider manufacturer based in Kirchheim unter Teck, Germany. History Martin Schempp founded his own company in Göppingen in 1935, with the assistance of Wolf Hirth. The company was initially called "Sportflugzeugbau Göppingen Martin Schempp". In 1938, Wolf Hirth, mainly responsible for the design work, officially became a partner in the company, which then became "Sportflugzeugbau Schempp-Hirth". The company relocated to Kirchheim unter Teck the same year. The company's first product was the Göppingen Gö 1 ''Wolf'' glider, conceived as a rival to the ubiquitous Grunau Baby, but real success came with the Göppingen Gö 3 ''Minimoa'' the same year. During World War II, the company built DFS Habicht training gliders, as well as tailplane assemblies for the Messerschmitt Bf 109. The company also built a research aircraft, the Göppingen Gö 9 to investigate Claude Dornier's rear-mounted " pusher" propeller plans. With its cruciform tai ...
