The Schempp-Hirth Janus is a high performance two-seat glider that was built by Schempp-Hirth GmbH. It was the first high-performance two-seater.
The Schempp-Hirth Nimbus-2 is an Open Class glider built by Schempp-Hirth during the 1970s. The Nimbus-2 first flew in April 1971 and a total of over 240 examples of all subtypes have been built until the beginning of the 1980s. It replaced the Schempp-Hirth Cirrus.
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.
The Akaflieg Berlin B12 is a high performance two-place glider aircraft that was designed and built in Germany. Conceived as a research vehicle, only one unit was constructed.
The Akaflieg Braunschweig SB-5 is a German single-seat Standard Class sailplane designed and prototyped by students of Brunswick University. More than 100 were built to their design, in several different variants.
The Akaflieg Darmstadt D-36 Circe is a single seat, high performance sailplane designed and built in Germany in the mid-1960s, one of the early "glass ships". It was the winner at the German National Championships in 1964 and came second in the World Championships the following year.
The Akaflieg Darmstadt D-40 is an experimental variable geometry single seat sailplane, fitted with almost full span, camber changing flaps for optimum aerodynamics in weak thermals and integrated into the wing so as to minimise flap tip drag. One flew successfully but the D-40, like other variable geometry sailplanes, was not commercialised.
The Akaflieg Braunschweig SB-11 is an experimental, single seat, variable geometry sailplane designed by aeronautical students in Germany. It won the 15 m span class at the World Gliding Championships of 1978 but its advances over the best, more conventional, opposition were not sufficient to lead to widespread imitation.
The Akaflieg Braunschweig SB-12 is a single seat, Standard Class sailplane designed around 1980 by German technical university students to test out a new wing profile from the German Aerospace Centre. It was not intended for production, but the sole SB-12 remains active in 2010.
The Akaflieg Stuttgart fs31 Ferdinand Porsche is a tandem seat, dual control training glider designed and built in Germany between 1977 and 1981. The aircraft was intended to have high performance, yet to be robust enough for student use. It was not intended for production and remains in service with the Akaflieg after almost 40 years and 7,100 flying hours.
The experimental Hirth Hi-25 Kria was only the second glider constructed from glass reinforced plastic (GRP). Built in Germany in 1958, it was a single seat, 12 m (39.4 ft) span aircraft. Only one was built; it later flew for several years with Akaflieg Stuttgart.
The Sunderland MOBA 2 was a single seat glider built in Australia in the 1970s. It was constructed from a mixture of metal, wood and synthetic material and had some unconventional features such as side-stick control, and a nosecone which rolled forward on rails for pilot access.
The Akaflieg Braunschweig SB-8 is an experimental, single-seat, high performance glider built in Germany in the 1960s, constructed largely from glass fibre skin over built up balsa wood structure. Two were built; the second of which was later fitted with a high aspect ratio (30:1) wing, becoming the Akaflieg Braunschweig SB-9 Stratus.
The Akaflieg Braunschweig SB-13 Arcus was an experimental tailless, single-seat, Standard Class glider designed and built in Germany in the early 1990s. Though it performed as well as its conventional contemporaries, it did not offer sufficiently improved performance to compensate for its difficult handling characteristics.
The Siebert Sie-3 is a single-seat Standard class glider designed and produced in Germany in the 1960s for club use.
The SZD-42 Jantar 2 is a single seat Open Class competition glider, designed and produced in Poland in the 1970s. It features a span of over 20 m (66 ft) and elastic, camber changing flaps. It was placed second, third and seventh at the 1976 World Gliding Championships. Over one hundred were built and more than ninety remain registered.
The Aérostructure Lutin 80, earlier known as the PLM 80, is a small, single seat motor glider with a low power pusher configuration engine, designed and built in France in the 1980s. Only two were completed.
The Akaflieg Braunschweig SB-6 Nixope was an early (1961) GRP high performance single seat glider designed and built in Germany by aeronautical students from Brunswick University. It competed in the 1961 German National gliding competition, coming sixth, and led directly to two further GRP aircraft.
The Schleicher K 10 is a Standard class competition glider, designed by Rudolf Kaiser and built in Germany in 1963. Only a few were produced.
The Akaflieg Braunschweig SB 14 is an 18 m (59 ft) Open-class sailplane designed and built in Germany in the early 2000s.
