Glider (sailplane)
A glider or sailplane is a type of glider aircraft used in the leisure activity and sport of gliding (also called soaring). This unpowered aircraft can use naturally occurring currents of rising air in the atmosphere to gain altitude. Sailplanes are aerodynamically streamlined and so can fly a significant distance forward for a small decrease in altitude. In North America the term 'sailplane' is also used to describe this type of aircraft. In other parts of the English-speaking world, the word 'glider' is more common. Types Gliders benefit from producing the least drag for any given amount of lift, and this is best achieved with long, thin wings, a slender fuselage and smooth surfaces with an absence of protuberances. Aircraft with these features are able to soar – climb efficiently in rising air produced by thermals or hills. In still air, sailplanes can glide long distances at high speed with a minimum loss of height in between. Sailplanes have rigid wings and eithe ...

Alexander Schleicher GmbH & Co
Alexander Schleicher GmbH & Co is a major manufacturer of sailplanes located in Poppenhausen, near Fulda in Germany. It is also the oldest sailplane manufacturer in the world. History The company was founded in 1927 by Alexander Schleicher using money that he had won as a pilot in a gliding competition. It grew quickly in size and fame, producing many notable designs including the ''Anfänger ("Beginner")'', ''Zögling ("Student")'', ''Professor'', ''Mannheim'', and the ''Stadt Frankfurt (City of Frankfurt)''. Meanwhile, the aircraft produced under contract by the company continued to grow in size and complexity, reaching their pinnacle with the ''DFS Rhönadler (Rhön eagle)'' and '' DFS Rhönbussard (Rhön buzzard)'' designed by Hans Jacobs, and a huge, three-seat experimental glider built from a design by Alexander Lippisch for the ''Deutsche Forschungsanstalt für Segelflug'' (DFS - German Research Institute for Sailplane Flight).

Wolf Hirth
Wolfram Kurt Erhard Hirth (28 February 1900 – 25 July 1959) was a German gliding pioneer and sailplane designer. He was a co-founder of Schempp-Hirth, still a renowned glider manufacturer.Segelflugbildkalendar 2011 Hirth was born in Stuttgart, the son of an engineer and tool-maker. He was the younger brother of Hellmuth, who founded the famous Hirth aircraft engine manufacturing company. Early years As a young man, Hirth took up gliding and was soon drawn to the Wasserkuppe, then the focus of the German gliding movement, earning his pilot's licence in 1920. In 1924, Hirth lost a leg after a motorcycle accident. From then on, he would fly while wearing a wooden prosthesis. He had the fibula from his amputated leg fashioned into a cigarette holder In 1928, he graduated from the Technical University of Stuttgart with a diploma in engineering and began to focus on aircraft construction. Over the next decade, he would also tour the world, promoting gliding throughout Europe, the Un ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akaflieg
Akaflieg is an abbreviation for ''Akademische Fliegergruppe'', groups of aeronautical engineering students from individual German Technical Universities, pre and postwar, who design aircraft, often gliders. History Otto Lilienthal published his book ''Der Vogelflug als Grundlage der Fliegekunst (Birdflight as the Basis of Aviation)'' in 1889. This described the basics of modern aerodynamics and aircraft construction. Lilienthal then made many successful flights starting in 1891. However attention then shifted to powered flight after World War I. Gliding re-emerged as a sport after the war because the building of powered aircraft was restricted in Germany by the Treaty of Versailles. The main originator of the gliding movement was Oskar Ursinus, who in 1920 organised the first contest, known as the Rhön-Contest, on the Wasserkuppe. Thereafter the contest was held annually. Students of technical universities brought gliders which they had developed and built themselves for test ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wolf Lemke
Wolf Lemke is a designer of gliders who worked for Rolladen Schneider and after it was taken over in 2003, for DG Flugzeugbau GmbH. He was one of the student members of the Akaflieg Darmstadt who designed the revolutionary D-36 "Circe" in the period 1962 to 1964. This team also included Heiko Fries, Klaus Holighaus and Gerhard Waibel. While the members of the Akaflieg built the D-36 (V1), a common friend of the students – Walter Schneider – built a second D-36 (V2) in his shutters factory. Walter Schneider almost killed himself in it when he took a winch launch with a disconnected elevator but he parachuted to safety. Soon after the success of the D-36 Walter Schneider asked Wolf Lemke to design and build gliders professionally in his shutters factory – which then became a glider manufacturer as well. His most significant design was the LS 1 which he first flew in May 1967. It was built by Walter Schneider, at first under the name Segelflugzeugbau Schneider OHG, but lat ...

Akaflieg Darmstadt D-36
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. Design and development The Akademische Fliegergruppe of the Technical University of Darmstadt ( Akaflieg Darmstadt) was first formed in 1921. It was, and is, a group of aeronautical students who design and construct aircraft as part of their studies and with the help and encouragement of their University. Design work on the Circe began in 1962-3 by a team of students, Wolf Lemke (responsible for the wing), Gerhard Waibel (fuselage and tail) and Heiko Friess (airbrakes). They were later joined by the younger Klaus Holighaus. Professor Franz Wortmann designed a new airfoil for the Circe. Construction began in 1963 and the aircraft flew for the first time, piloted by Wolf Lemke, on 28 March 1964 at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Schleicher ASW 12
The ASW 12, initially known as the AS 12, is a single-seat Sailplane of glass composite construction. The wing is shoulder mounted and it has a T-tail. It is essentially a developed production version of the Akaflieg Darmstadt D-36. History In 1965 Gerhard Waibel left the Technical University of Darmstadt to enter Alexander Schleicher GmbH & Co as a designer. His first project for his new employer was the ASW 12. This sailplane achieved numerous records and victories in national and international competitions. The exploits of Hans-Werner Grosse in an ASW 12 are legendary, e.g. the 1,461 km flight of April 25, 1972 from Lübeck to Biarritz which stood for thirty years as the absolute World Free Distance Record. Previously, on July 26, 1970, Ben Greene and Wally Scott co-set a World Free Distance Record by flying separate ASW-12 sailplanes a distance of from Odessa, TX to Columbus, NE. The ASW12 was succeeded by the ASW17. Construction The fuselage of the ASW 12 was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
