DFS Seeadler
The DFS Seeadler (Sea Eagle) was a German flying boat sailplane designed by Hans Jacobs of the Deutsche Forschungsanstalt für Segelflug (DFS). It was version of the 1935 DFS Rhönadler, with a new fuselage and strongly gulled wings to keep them clear from spray. The aircraft was first flown in the summer of 1935, test piloted by Hanna Reitsch, and towed by a Dornier Do 12 The Dornier Do 12 ''Libelle'' III ("Dragonfly III") was the third of a line of small German flying boats of the 1930s. It started with the Dornier A Libelle I and the Dornier A Libelle II, though the Do 12 was not a continuation, but an entire ....

Flying Boat
A flying boat is a type of fixed-winged seaplane with a hull, allowing it to land on water. It differs from a floatplane in that a flying boat's fuselage is purpose-designed for floatation and contains a hull, while floatplanes rely on fuselage-mounted floats for buoyancy. Though the fuselage provides buoyancy, flying boats may also utilize under-wing floats or wing-like projections (called sponsons) extending from the fuselage for additional stability. Flying boats often lack landing gear which would allow them to land on the ground, though many modern designs are convertible amphibious aircraft which may switch between landing gear and flotation mode for water or ground takeoff and landing. Ascending into common use during the First World War, flying boats rapidly grew in both scale and capability during the interwar period, during which time numerous operators found commercial success with the type. Flying boats were some of the largest aircraft of the first half of the 2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Germany
Germany,, officially the Federal Republic of Germany, is a country in Central Europe. It is the second most populous country in Europe after Russia, and the most populous member state of the European Union. Germany is situated between the Baltic and North seas to the north, and the Alps to the south; it covers an area of , with a population of almost 84 million within its 16 constituent states. Germany borders Denmark to the north, Poland and the Czech Republic to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its financial centre is Frankfurt; the largest urban area is the Ruhr. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the bulk of the Holy Roman Empire. During the 16th ce ... [...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] |
Hans Jacobs
Hans Jacobs (30 April 1907 in Hamburg - 24 October 1994) was a German sailplane designer and pioneer. He had been taught sailplane design by Alexander Lippisch, designer of many gliders during the 1920s and the 1930s. As the head of the ''Deutsche Forschungsanstalt für Segelflug'' (DFS - German Research Institute for Sailplane Flight) at Darmstadt in the years before World War II, he was responsible for a number of highly successful designs, including the DFS Rhönsperber, DFS Rhönadler, DFS Habicht, DFS Weihe, DFS Kranich, and the DFS 230 assault glider. Hans also designed a glider-seaplane, the "Sea Eagle", test flown by Hanna Reitsch.Reitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, In 1936, Hans developed self-operating dive brakes, on the upper and lower surface of each wing, for gliders. He designed the DFS 230 used in the Battle of Fort Eben-Emael. The DFS Olympia Meise was selected in 1939 as the glider for the 1940 Summer Oly ...

Gull Wing
The gull wing is an aircraft wing configuration, known also as ''Pulaski wings'', with a prominent bend in the wing inner section towards the wing root. Its name is derived from the seabirds which it resembles. Numerous aircraft have incorporated such wings for a diverse range of purposes. The gull wing was commonly used to improve visibility in a high wing arrangement, because such wing could be thinnest by the fuselage, and in theory should limit pilot's view no more than A-pillars of a windscreen in a car body. Gliders were the first aircraft to feature the gull wing, starting with the Weltensegler in 1921; it was not until the record-breaking Fafnir at the end of that decade did the configuration gain popularity. Beyond becoming popular for the next three decades amongst high-performance gliders, various ground-based aircraft and flying boats also adopted various forms of gull wings. It rose to particular prominence in Poland, where the Polish aviation designer Zygmunt P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hanna Reitsch
Hanna Reitsch (29 March 1912 – 24 August 1979) was a German aviator and test pilot. Along with Melitta von Stauffenberg, she flight tested many of Germany's new aircraft during World War II and received many honors. Reitsch was among the very last people to meet Adolf Hitler alive in the in late April 1945. Reitsch set more than 40 flight altitude records and women's endurance records in gliding and unpowered flight, before and after World War II. In the 1960s, she was sponsored by the West German foreign office as a technical adviser in Ghana and elsewhere, and founded a gliding school in Ghana, where she worked for Kwame Nkrumah. Early life and education Reitsch was born in Hirschberg, Silesia, on 29 March 1912 to an upper-middle-class family. She was daughter of Dr. Wilhelm (Willy) Reitsch, who was an ophthalmology clinic manager, and his wife Emy Helff-Hibler von Alpenheim, who was a member of the Austrian nobility. Despite her mother being a devout Cathol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dornier Do 12
The Dornier Do 12 ''Libelle'' III ("Dragonfly III") was the third of a line of small German flying boats of the 1930s. It started with the Dornier A Libelle I and the Dornier A Libelle II, though the Do 12 was not a continuation, but an entirely new aircraft. The aircraft was amphibious and would carry three to four passengers. It was powered by a single Argus As 10 engine initially, then a Gnome-Rhône 5Ke Titan engine, mounted above the wing. It first flew in 1932 and went on to be used by the DFS to tow gliders. Design The Do 12 was a high-wing monoplane, of usual Dornier all-metal construction, with a two-spar, trapezoidal wing, whose trailing edge was very strongly rounded at the root. The fuselage was of rectangular cross-section. A storage area was in the nose, where equipment, including anchors, could be kept. Behind it, the open cockpit had two side-by-side seats, with optional dual controls. In the cabin, there were two more seats and a storage area, which could a ...

1930s German Sailplanes
Year 193 ( CXCIII) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Sosius and Ericius (or, less frequently, year 946 ''Ab urbe condita''). The denomination 193 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.
