Standard Cirrus
The Standard Cirrus is a German Standard-class glider built by Schempp-Hirth. The Standard Cirrus was produced between 1969 and 1985, when it was replaced by the Discus. Over 800 examples were built, making it one of the most successful early fibreglass glider designs. Development The Standard Cirrus was designed by Dipl. Ing. Klaus Holighaus and flew for the first time in February 1969. It is a Standard Class glider with a 15-metre span, and laminar-flow airfoil section designed by Professor Franz Wortmann. The all-moving tailplane, a feature of many designs of that period due to its theoretically higher efficiency, caused less than desirable high-speed stability characteristics, and so modifications were made to the early design. Even so, the glider is still very sensitive in pitch. The aircraft built before 1972 have a washout of -0.75 degrees. The washout was then increased to -1.5 degrees which improved low-speed performance and response at slow speed. Improvements w ...

Ailerons
An aileron (French for "little wing" or "fin") is a hinged flight control surface usually forming part of the trailing edge of each wing of a fixed-wing aircraft. Ailerons are used in pairs to control the aircraft in Flight dynamics, roll (or movement around the aircraft's Flight control surfaces#Longitudinal axis, longitudinal axis), which normally results in a change in flight path due to the tilting of the Lift (force), lift vector. Movement around this axis is called 'rolling' or 'banking'. Considerable controversy exists over credit for the invention of the aileron. The Wright brothers and Glenn Curtiss fought a years-long Wright brothers patent war, legal battle over the Wright patent of 1906, which described a method of wing-warping to achieve lateral control. The brothers prevailed in several court decisions which found that Curtiss's use of ailerons violated the Wright patent. Ultimately, the World War I, First World War compelled the U.S. Government to legislate a le ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schempp-Hirth Aircraft
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 tail, t ...

1960s German Sailplanes
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 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.

Schleicher ASW 15
The Schleicher ASW 15 is a single-seat sailplane designed in 1968 by Gerhard Waibel (engineer), Gerhard Waibel and manufactured by Alexander Schleicher GmbH & Co. The ASW 15 has shoulder-mounted wings and an all-flying tailplane, with its single tow-release placement a compromise between winching and aerotowing. The later ASW 15B had several improvements, including a tow-release placed on the plane of symmetry, an 11 cm taller rudder, a slightly larger main wheel, and the provision of a 90-litre water ballast system. Rot due to fungus infestation was found in an early example, leading to an Airworthiness Directive. Starting with serial number 356, balsa wood was abandoned in the construction in favour of synthetic foam. In 1971 and 1972, the American pilot Karl Striedieck set world out-and-return distance soaring records three times flying an ASW 15, including one flight of on October 15, 1972. It was succeeded by the Schleicher ASW 19. Variants ;ASW 15:Original producti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolladen-Schneider LS1
The Rolladen-Schneider LS1 is a Standard Class single-seat glider manufactured in Germany by Rolladen-Schneider from 1968 to 1977. Development The LS-1 Standard Class design was the first aircraft type arising from the partnership between Wolf Lemke and Walter Schneider, who had already worked together as students on the ground breaking Akaflieg Darmstadt D-36. Here, and in subsequent Lemke-Schneider (LS) designs, Wolf Lemke concentrated on the aerodynamics while Walter Schneider contributed mostly to the structural and production issues. The LS1 made its debut at the 1968 German National Championships, taking first and second place with the designers themselves at the controls. The success of this design increased in the subsequent years until, in 1975, it was the most flown glider in the German Nationals. The LS1-c took first place in the 1970 World Championships at Marfa, Texas. The manufacture of the LS1 was discontinued after the IGC introduced the new unrestricted 15 ...

Glasflügel H-201 Standard Libelle
The firm Glasflügel (german: glass wings) was founded by Eugen Hänle in 1962 and was located in Schlattstall, south of Kirchheim unter Teck. It was the first firm to manufacture a glass-fibre sailplane in large numbers. It was also responsible for a large number of innovations in sailplane design and technology: quick assembly systems for wings and tailplane, automatic control connections, trailing edge airbrake-flap combinations, hinged instrument panels, the parallelogram control stick and automatic trimming are some innovations introduced by Glasflügel and later adopted by other manufacturers. Some of these are standard features in nearly all gliders produced today. Glasflügel encountered financial difficulties in the 1970s which led to a co-operation with the firm Schempp-Hirth starting from May 1975. The death of Eugen Hänle in a flight accident on September 21 of the same year further aggravated the company's position, and after further changes in ownership in 1979, i ...

Bölkow Phoebus
The Bölkow Phoebus is a glass fibre composite competition sailplane, designed and produced in Germany in the 1960s. Large numbers were built, achieving success at some national contests, and many remain active. Design and development The Phoebus was designed at a time when glider manufacturers were moving away from all-wood aircraft towards composite structures. Bölkow had been among the early leaders of this change with their Phönix T sailplane in the late 1950s, which used balsa/glassfibre sandwich construction. The Phoebus was built in the same way. It is a shoulder wing competition sailplane. The first aircraft, the Phoebus A, was designed to Standard Class rules, with a span of 15 m. Its straight tapered wings have an aspect ratio of 17.1; airbrakes are fitted at 70% chord. The fin and rudder are straight edged and only slightly tapered, with a high aspect ratio all moving T tail. The fuselage is a monocoque with the cockpit, ahead of the wings, enclosed with a o ...

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. A list of future events is available here World Grand Prix Gliding Champ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
