Schneider Grunau 9
The ESG Grunau 9, later known as the ESG 29 and post-1933 as the DFS 108-10, was one of the first primary gliders, built in Germany from the late 1920s. It was widely sold. Design and development The Grunau 9 was a German single seat trainer glider, one of the first of a group that later became known as primary gliders. It was developed by Edmund Schneider from Alexander Lippisch's Djävlar Anamma (german: Hols der Teufel, en, to the Devil with it) via the Espenlaub primary. The Grunau 9 was produced in numbers and was sold widely. The core of the flat frame fuselage was formed with a horizontal beam about long, to which two other converging struts were attached, making overall a vertical A-frame. The downward sloping extremities of these beams carried a slightly deeper horizontal box structure below the cross beam, with the open pilot's seat and controls upon it. On some later aircraft there was an extra vertical member for the lower cross beam to the wing root to pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Primary Glider
Primary gliders are a category of aircraft that enjoyed worldwide popularity during the 1920s and 1930s as people strove for simple and inexpensive ways to learn to fly.Schweizer, Paul A: ''Wings Like Eagles, The Story of Soaring in the United States'', pages 14-22. Smithsonian Institution Press, 1988. Constructed of wood, metal cables and cloth, primary gliders were very light and easy to fly. They generally had no cockpit and no instruments. Operations Primary gliders were generally launched by bungee cord, whereby a rubber rope was arranged in a "V" with the glider at the apex. The ends of the rope were pulled by hand to launch the glider from a slope. Primaries were also launched by auto-tow Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is al ... and auto-bungee tow. Ramp launching ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chord (aircraft)
In aeronautics, the chord is an imaginary straight line joining the leading edge and trailing edge of an aerofoil. The chord length is the distance between the trailing edge and the point where the chord intersects the leading edge.L. J. Clancy (1975), ''Aerodynamics'', Section 5.2, Pitman Publishing Limited, London. The point on the leading edge used to define the chord may be the surface point of minimum radius. p.18 For a turbine aerofoil the chord may be defined by the line between points where the front and rear of a 2-dimensional blade section would touch a flat surface when laid convex-side up. The wing, horizontal stabilizer, vertical stabilizer and propeller/rotor blades of an aircraft are all based on aerofoil sections, and the term ''chord'' or ''chord length'' is also used to describe their width. The chord of a wing, stabilizer and propeller is determined by measuring the distance between leading and trailing edges in the direction of the airflow. (If a wing has ...

Akureyri
Akureyri (, locally ) is a town in northern Iceland. It is Iceland's fifth-largest municipality, after Reykjavík, Hafnarfjörður, Reykjanesbær and Kópavogur, and the largest town outside Iceland's more populated southwest corner. Nicknamed the "Capital of North Iceland", Akureyri is an important port and fishing centre. The area where Akureyri is located was settled in the 9th century, but did not receive a municipal charter until 1786. Allied units were based in the town during World War II. Further growth occurred after the war as the Icelandic population increasingly moved to urban areas. The area has a relatively mild climate because of geographical factors, and the town's ice-free harbour has played a significant role in its history. History The Norse Viking Helgi ''magri'' (the slim) Eyvindarson originally settled the area in the 9th century. The first mention of Akureyri is in court records from 1562, when a woman was sentenced there for adultery. In the 17th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icelandic Aviation Museum
The Aviation Museum of Iceland ( is, Flugsafn Íslands ) covers the history of aviation in Iceland. It is housed at Akureyri Airport and was formally opened on 24 June 2000. History The museum was founded on 1 May 1999 and formally opened on 24 June 2000 by Halldór Blöndal, the Speaker of the Althing. It was initially known as the Aviation Museum at Akureyri; another aviation collection existed at Hnjótur in Örlygshöfn. It was renamed in 2005 to reflect its national role. Svanbjörn Sigurðsson, a principal figure in the foundation of the museum, was its first director. Initially in temporary quarters in a hangar rented by Íslandsbanki, the museum moved in 2007 to a purpose-built building with of space, approximately five times what it previously had; the building was officially opened by Sigrún Björk Jakobsdóttir, the mayor of Akureyri. It celebrated its tenth anniversary in 2009. The aircraft collection has been used for training by the . Collection The museum has m ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Deutsche Forschungsanstalt Für Segelflug
The ''Deutsche Forschungsanstalt für Segelflug'' (), or DFS , was formed in 1933 to centralise all gliding activity in Germany, under the directorship of Professor Walter Georgii. It was formed by the nationalisation of the Rhön-Rossitten Gesellschaft (RRG) at Darmstadt.Reitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, The DFS was involved in producing training sailplanes for the Hitler Youth and Luftwaffe, as well as conducting research into advanced technologies such as flying wings and rocket propulsion. Notable DFS-produced aircraft include the DFS 230 transport glider (1600+ produced), the German counterpart to the British Airspeed Horsa glider, and the DFS 194, similar to the famous Messerschmitt Me 163 rocket fighter. In 1938, following a fatal accident at the Wasserkuppe, DFS held a competition to design a more effective speed brake for gliders. The final design, produced by Wolfgang and Ulrich Hütter of Schempp-Hirth, is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elevator (aircraft)
Elevators are flight control surfaces, usually at the rear of an aircraft, which control the aircraft's pitch, and therefore the angle of attack and the lift of the wing. The elevators are usually hinged to the tailplane or horizontal stabilizer. They may be the only pitch control surface present, and are sometimes located at the front of the aircraft (early airplanes) or integrated into a rear "all-moving tailplane", also called a slab elevator or stabilator. Elevator control effectiveness The elevator is a usable up and down system that controls the plane, horizontal stabilizer usually creates a ''downward'' force which balances the nose down moment created by the wing lift force, which typically applies at a point (the wing center of lift) situated aft of the airplane's center of gravity. The effects of drag and changing the engine thrust may also result in pitch moments that need to be compensated with the horizontal stabilizer. Both the horizontal stabilizer and ...
