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.
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 Schleicher ASW 15 is a one-seat sailplane designed in 1968 by 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.
The Glaser-Dirks DG-400 is a single-seat self-launching motorglider that was produced by Glaser-Dirks between 1981 and 1992. It was the first self-launching motorglider with retractable engine and propeller to be produced in large numbers.
The ASW 19 is a single-seat glider built by Alexander Schleicher GmbH & Co, first flying in 1975. It was originally designed as a Standard Class glider, but now mainly competes in the Club Class. The ASW 19 is known for its pleasant handling and some clubs use it as a training glider. It was succeeded by the all-new Schleicher ASW 24.
The SZD-45 Ogar (Hound) is a T-tailed cantilever high-wing monoplane of wooden, aluminium and fibreglass construction designed and manufactured in Poland.
The ICA IS-29 was a sailplane built in Romania in the 1970s. The prefix IS comes from Iosif Șilimon, the Romanian IAR aeronautical engineer who designed it.
The Hindustan Ardhra was a sailplane designed in India for pilot training by the government's Civil Aviation Department in the late 1970s as the ATS-1 Ardhra. It was a two-seat aircraft of conventional configuration and wooden construction. The Indian Air Force ordered fifty examples in the early 1980s to be produced by Hindustan Aeronautics and the type was approved for use for flying by cadets.
The Schleicher ASK 23 is a single-seat Club Class sailplane that was built by the German manufacturer Alexander Schleicher GmbH & Co.
The VSO 10 Vosa is a Standard and Club-Class glider designed and manufactured in the Czechoslovak Republic from December 1978 as a replacement for the VT-116 Orlik II.
The ICA IS-28 is a two-seat sailplane produced in Romania in the 1970s. An all-metal aircraft of conventional design with a T-tail, it was originally produced with 15-metre wings, but in 1973, production shifted to the IS-28B with 17-metre wings and numerous aerodynamic refinements. These included a smaller tail with decreased dihedral, decreased dihedral on the wings, and redesigned fuselage contours. This version first flew on 26 April 1973 and was subsequently produced in versions with flaps (IS-28B2) and without (IS-28B1). Around 100 had been built by the early 1980s, with a substantial number sold for export. On April 7, 1979, Tom Knauff and R. Tawse set a world record with the IS-28 B2 glider, covering a distance of 829 kilometres on a predetermined out-and-return course from the Ridge Soaring Gliderport in Julian, Pennsylvania.
The Schweizer SGS 1-36 Sprite is a United States, single-seat, mid-wing glider built by Schweizer Aircraft of Elmira, New York.
The Scheibe SF 34 Delphin is a two-seat sailplane that was produced by Scheibe in Germany in the late 1970s and 1980s. Designed by Wolf Hoffmann and originally designated the SF H34, it was Scheibe's first unpowered aircraft of composite construction.
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 PZL Bielsko SZD-51 Junior is a Polish single-seat training and club sailplane.
The LAK-12 is a Lithuanian mid-wing, single-seat, FAI Open Class glider that was designed and produced by Lietuviškos Aviacinės Konstrukcijos (LAK) in Lithuania and later by Sportine Aviacija and Sport Aviation USSR.
The Akaflieg Darmstadt D-39 was a single-seat motor glider derived from the D-38 sailplane. Built in Germany in the late 1970s, it was not intended for production and only one was constructed.
The FVA-20 F. B. Schmetz was a single seat, Standard Class sailplane, built as a one-off aircraft, to explore the application of glass fibre to glider construction. Built over a long period, it finally flew in late 1979.
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 Mistral-C was one of the first gliders, designed in 1974 to the then new Club Class rules. It was based on the Strauber Mistral, a Standard Class glider flown a year earlier, but with a new wing and built from newer composite materials. Both types were designed and constructed in Germany. More than 75 Mistral-Cs were produced.
