Schempp-Hirth Nimbus-2
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. Design and development Loosely based on the original Nimbus HS-3 prototype, the production version that eventually surfaced as the Nimbus-2 was a very different glider with many improvements over the problematic prototype. The wing was shortened to 20.3 metres and was built in four sections to make it easier to rig and transport. It received Schempp-Hirth air brakes fitted in the upper surfaces and a tail braking-parachute, plus camber-changing flaps. It had an all-flying T-tail similar to the Standard Cirrus as well as the general layout of its fuselage. The Nimbus-2 was successful in competitions, twice winning the Open Class in World Gliding Championships: Göran Ax (Sweden) in 1972 and George Moffat (USA) in ...

Glasflügel 303
The Glasflügel 303 Mosquito is a composite 15 metre Class single-seat sailplane manufactured by Glasflügel between 1976 and 1980. Design and development Designed for the 15 metre racing class, the Mosquito married the Standard Class Hornet fuselage with a flapped wing employing the then widely-used FX 67-K-170 airfoil developed at the University of Stuttgart by Professor Franz Wortmann. The Mosquito had a new design of one-piece canopy rather than the two-piece canopy used on the Hornet. This profile and its sister profile FX 67-K-150 are among the most prolific in the history of gliding, as they were employed also in the Nimbus-2, Mini-Nimbus, DG-200 and DG-400, PIK-20, Kestrel, Mosquito, Vega, Jantar and LAK-12 among other types. The 303 wing featured innovative interconnected trailing edge dive brakes-variable camber flaps. The glider had automatic connection for all controls: ailerons, elevator, air brakes and water ballast. The Mosquito also uses a pneumatic ...

Motor Gliders
An engine or motor is a machine designed to convert one or more forms of energy into mechanical energy. Available energy sources include potential energy (e.g. energy of the Earth's gravitational field as exploited in hydroelectric power generation), heat energy (e.g. geothermal), chemical energy, electric potential and nuclear energy (from nuclear fission or nuclear fusion). Many of these processes generate heat as an intermediate energy form, so heat engines have special importance. Some natural processes, such as atmospheric convection cells convert environmental heat into motion (e.g. in the form of rising air currents). Mechanical energy is of particular importance in transportation, but also plays a role in many industrial processes such as cutting, grinding, crushing, and mixing. Mechanical heat engines convert heat into work via various thermodynamic processes. The internal combustion engine is perhaps the most common example of a mechanical heat engine, in which he ...

1970s German Sailplanes
Year 197 ( CXCVII) was a common year starting on Saturday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Magius and Rufinus (or, less frequently, year 950 ''Ab urbe condita''). The denomination 197 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 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 ...

LAK-9
The LAK-9 ''Lietuva'' ( en, Lithuania) was an open-class competition sailplane produced in the Soviet Union in the 1970s. It was based on the LAK BK-7 that had been produced in small numbers since 1972. Like it, the LAK-9 was a conventional sailplane design with a high-set cantilever wing and a conventional empennage. The landing gear consisted of a retractable monowheel and a tailwheel, and construction throughout was of fibreglass. The type came to the attention of the West when a LAK-9 was flown in the 1976 Gliding World Championships in Finland, the first entry by the Soviet Union since 1968. Piloted by O. Pasetnik, it was withdrawn from competition due to aileron damage. The fourth batch to be produced was designated the LAK-9M (for "Modernised"), and a motorglider A motor glider is a fixed-wing aircraft that can be flown with or without engine power.
