Glaser-Dirks DG-200
The Glaser-Dirks DG-200 is a 15 metre class glider built by Glaser-Dirks, now DG Aviation GmbH Design started in 1976, and it first flew in 1977. Wingtip extensions to 17 metres were offered in 1978. Later enhancements included a single-piece canopy, a carbon-fibre wing spar and a change in the wing profile. A total of 192 DG-200 were built. The glider designs * a two-piece conventional elevator, with a fixed forward stabilizer and aft-mounted movable elevator. * a control stick with a parallelogram linkage to reduce pilot self-indiced acceleration. * a schempp-hirth airbrakes, on top surface only * a 5"x5" main wheel (drum brake) and a 200x50 tail wheel * l'Hottelier connection for the ailerons, airbrakes and elevator (elevator connection is automatic on the DG-202).

Alexander Schleicher ASW 20
The ASW 20 is an FAI 15 metre Class glider designed by Gerhard Waibel and built by Alexander Schleicher GmbH & Co. Its fuselage is nearly identical to that of the ASW 19, mated to newly designed flapped wings for the 15 metre Class. The prototype first flew in 1977. It proved to be a highly successful glider, winning several World Championships, and was still being flown at this level up to 1995. Developments along its production life included winglets, pneumatic turbulators, and wingtip extensions. It remained in production until 1990, when it was superseded by the ASW 27. 765 were built by Schleicher and a further 140 were made under license by Centrair in France. The ASW 20 was successful in competition, winning numerous world and national championships. Dick Johnson reported that the ASW 20 was the first 15 m glider to demonstrate a measured L/D in excess of 40:1. Roy McMaster, Karl Striedieck and John Seymour won jointly, with others, the world triangle distance rec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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. Events By place Roman Empire * February 19 – Battle of Lugdunum: Emperor Septimius Severus defeats the self-proclaimed emperor Clodius Albinus at Lugdunum (modern Lyon). Albinus commits suicide; legionaries sack the town. * Septimius Severus returns to Rome and has about 30 of Albinus's supporters in the Senate executed. After his victory he declares himself the adopted son of the late Marcus Aurelius. * Septimius Severus forms new naval units, manning all the triremes in Italy with heavily armed troops for war in the East.

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 ...

Eiri-Avion PIK-20
The PIK-20 sailplane was designed at the Helsinki University of Technology by Pekka Tammi, with advice from Ilkka Rantasalo and Raimo Nurminen. The prototype first flew on 10 October 1973. It was produced initially by Molino Oy who were taken over by Eiri-Avion Oy (currently Eirikuva Oy) between 1974 and 1980. Later, production was taken over by the French company, Siren SA, under the name Siren PIK-20. At first the PIK-20 was classified as a Standard Class glider, which at the time allowed either flaps or air-brakes for landing approach control. The specification of the Standard Class required the air-brakes or flaps to be capable of keeping the speed below the maximum speed in a vertical dive. However at high speed great force was needed to fully lower the flaps and so the PIK-20 was equipped with a geared crank handle. The first prototype finished 13th in the World Gliding Championships in Waikerie in January 1974 but it performed impressively. (The low placing was caused ...

Schempp-Hirth Mini-Nimbus
The Schempp-Hirth Mini Nimbus is a 15 Metre-class glider designed and built by Schempp-Hirth GmbH in the late 1970s. Design and development In designing the Mini-Nimbus, Klaus Holighaus incorporated the flapped wings from the Glasflügel 303 Mosquito, with the fuselage of the Standard Cirrus. The wings feature trailing edge terminal speed dive brakes-variable camber flaps that limit the vertical dive speed to a maximum of 70 knots when the dive brakes are fully deployed. The name "Mini Nimbus" was adopted to distinguish it from longer-wingspan Nimbus models. It first flew on 18 September 1976. The Mini Nimbus range all feature self-connecting controls, of Glasflügel design, for added safety and ease of rigging, and have been incorporated in all newer Schempp-Hirth models. The trim lever is connected to the flap operating rod and needs to be set only once per flight; thereafter changes in flap setting (-7 to +10 degrees) automatically provides trim compensation.

Rolladen-Schneider LS3
The Rolladen-Schneider LS3 is a 15 metre single-seat glider produced by Rolladen-Schneider from 1976 to 1983. Development and design The LS3 was developed as Rolladen-Schneider's first entry to the new 15-metre competition class created in 1974 by the International Gliding Commission of the Fédération Aéronautique Internationale. Building upon previous experience with the LS1 and LS2, chief designer Wolf Lemke developed a new fuselage with a larger cockpit and more generous horizontal and vertical stabilisers. Lemke selected a relatively thick airfoil profile developed in 1967 by University of Stuttgart Professor Franz Wortmann, the FX 67-K-170, which offered the structural economy made possible by a tall spar - an important consideration as glass fibre was still the only affordable reinforcement material - as well as good performance for the time. This profile and its sister profile FX 67-K-150 are among the most prolific in the history of gliding, as they were employe ...

Glaser-Dirks DG-400
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. Development The cost of carbon-fibre had fallen enough in the late 1970s to allow its use in the wing spars of high-performance gliders. Glaser-Dirks introduced a carbon wing variant of the DG-200 about this time. Designer Wilhelm Dirks realised that the span, strength and very low weight of this wing allowed for a self-launching engine to be carried in the glider without an unacceptable penalty when soaring in weak conditions. The DG-400 was created as a result. It first flew in May 1981. The DG-400 uses the wings and most systems of the DG-202. It has a modified fuselage with a slightly enlarged tailcone and carbon fibre reinforcements to accommodate the engine An engine or motor is a machine designed to convert one or more forms o ...

Aerofoil
An airfoil (American English) or aerofoil (British English) is the cross-sectional shape of an object whose motion through a gas is capable of generating significant lift, such as a wing, a sail, or the blades of propeller, rotor, or turbine. A solid body moving through a fluid produces an aerodynamic force. The component of this force perpendicular to the relative freestream velocity is called lift. The component parallel to the relative freestream velocity is called drag. An airfoil is a streamlined shape that is capable of generating significantly more lift than drag. Airfoils can be designed for use at different speeds by modifying their geometry: those for subsonic flight generally have a rounded leading edge, while those designed for supersonic flight tend to be slimmer with a sharp leading edge. All have a sharp trailing edge. Foils of similar function designed with water as the working fluid are called hydrofoils. The lift on an airfoil is primarily the result o ...
