open class sailplanes – typically around 60:1, but in more common 15–18 meter span aircraft, glide ratios are between 38:1 and 52:1; [4] high glide performance enabling long distance flight, with 3,000 kilometres (1,900 mi) being current (as of November 2010) record [5]
The SGS 2-33, indicating Schweizer Glider, Sailplane, 2 Seats, Model 33, was designed by Ernest Schweizer. The aircraft was a derivative of the 2-22, which in turn was based on the SGU 1-7 single place glider of 1937. The 2-33 retained the 2-22 and 1-7's metal wing, single spar and single strut arrangement. [1] [2] [5]
Rolladen-Schneider LS4 (video) A glider sails over Gunma, Japan. A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). [1] [2] This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically ...
The ASW 28 is a Standard Class glider with a fifteen-metre span built of modern fibre reinforced composites. The manufacturer of the ASW-28 is Alexander Schleicher GmbH & Co. The 'W' indicates this is a design of the influential and prolific German designer Gerhard Waibel. Serial production started in 2000.
The Jonker JS-3 Rapture is a glider built of glass-fibre, carbon fibre and Kevlar. It has full-span flaps and can be operated with a wingspan of either 15 m (49.2 ft) or 18 m (59.1 ft). [2] [3] [4] The manufacturer is Jonker Sailplanes of Potchefstroom South Africa, founded in 2004 by two brothers
The 2-32 was designed to be the highest performance two-place glider available, when it first flew in 1962. The 2-32 has been used as a tourist glider, trainer, cross-country and high-altitude sailplane and has set many US and world records. A total of 87 aircraft were completed. [1] [3] [4] [5]
Single-seat high performance fiberglass Glaser-Dirks DG-808 glider Aerobatic glider with tip smoke, pictured on July 2, 2005, in Lappeenranta, Finland. A glider is a fixed-wing aircraft that is supported in flight by the dynamic reaction of the air against its lifting surfaces, and whose free flight does not depend on an engine. [1]
At that time the Schweizer SGS 1-23 was the only sailplane in production in the United States and demand for it had dropped off, due to its high price. At the same time the number of people participating in soaring had increased and there was a clear market for a low cost sailplane. [2] Design goals for the new glider included: [2] available as ...
