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, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RRG Professor
The RRG Professor was a very early soaring glider and the first to use a variometer for finding thermals. It was designed by Alexander Lippisch in Germany, first flying in 1928. The Professor was widely built by both flying clubs and factories. Design and development In early 1928 Professor Walter Georgii, an academic meteorologist and head of the Rhön-Rossitten Gesellschaft (RRG), began studies of thermals, previously assumed to be too weak to assist gliders. He directed flights of a light, powered aircraft which, with its engine idling, discovered uplifts of several metres per second. At about the same time Alexander Lippisch, who had earlier worked at Dornier Flugzeugwerke, Dornier on Zeppelins was considering the application of the variometer to gliding. These rapid response rate of climb instruments were known in lighter-than-air craft but had not been used on gliders. The two came together to produce a glider, designed by Lippisch and built at the RRG that had the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twin Boom
A twin-boom aircraft is characterised by two longitudinal booms (extended nacelle-like bodies). The booms may contain ancillary items such as fuel tanks and/or provide a supporting structure for other items. Typically, twin tailbooms support the tail surfaces, although on some types such as the Rutan Model 72 Grizzly the booms run forward of the wing. The twin-boom configuration is distinct from twin-fuselage designs in that it retains a central fuselage. Design The twin-boom configuration is distinct from the twin fuselage type in having a separate, short fuselage housing the pilot and payload. It has been adopted to resolve various design problems with the conventional empennage for aircraft in different roles. Engine mounting For a single engine with a propeller in the pusher configuration or a jet engine, a conventional tail requires the propeller or exhaust to be moved far aft, requiring either a very long driveshaft or jet pipe and thus reducing propulsive effic ...

DFS Zögling
The Zögling ( en, pupil) is a German high-wing, cable-braced, single seat primary glider that was designed by Alexander Lippisch in 1926 and produced with many variations by a variety of manufacturers. Design and development The Zögling was designed to be a training glider for basic flight training. The usual launch method was by bungee cord from a sloped hill. Because training was conducted solely by solo flight the aircraft had to be very easy to fly and also easy to repair. The high-wing design uses a kingpost and cable bracing. The primary structure of the glider is of wood, with the wings, tail surfaces and inverted "V" kingpost all finished in doped aircraft fabric covering. The pilot sits on a simple seat in the open air, without a windshield. Variants ;D.D.

DFS 346
The DFS 346 (''Samolyot 346'') was a German rocket-powered swept-wing aircraft which began development during World War II in Germany. It was designed by Felix Kracht at the ''Deutsche Forschungsanstalt für Segelflug'' (DFS), the "German Institute for Sailplane Flight". A prototype was constructed but did not reach completion before the end of the war. It was taken to the Soviet Union where it was completed, tested and flown (with indifferent success). Design The DFS-346 was a midwing design of all-metal construction. The front fuselage of the 346 was a body of rotation based on the NACA-Profile 0012-0,66-50. The middle part was approximately cylindrical and narrowed to the cut off to accommodate vertically arrayed nozzles in back. Probably for volume and weight reasons the DFS-346 was equipped with landing skids, both in the original German design and in the later Soviet prototypes; this caused trouble several times. The wings had a 45° swept NACA 0012-0,55-1,25 profile o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS 332
The DFS 332 was an experimental aircraft, built by the Deutsche Forschungsanstalt für Segelflug (DFS). Development It was designed to evaluate new wing profiles in flight. For this purpose, the DFS 332 was given twin fuselages, of a long and slender shape with flat sides. The front of the left fuselage contained a cockpit for the pilot, and the right fuselage a seat for an engineer who would operate the measurement instrumentation. The wing section to study would be attached between the fuselages, with fittings that allowed an easy exchange. The short outer wing panels were fixed, with slightly swept leading edges and straight trailing edges with full-span ailerons. Each fuselage had its own tailfin, with a tailplane and elevator between them. The DFS 332 was a glider, a configuration that presumably had advantages for aerodynamic testing because the airflow over the wing would not be disturbed by a propeller. The design of the fuselages, with flat wall sides and noses that exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS 331
The DFS 331 was a transport glider prototype developed in a collaboration between DFS and Gotha. It was a twenty-seat troop transport designed by Hans Jacobs, who had previously produced the successful, nine seat DFS 230. The visibility from the cockpit was good, with the entire nose being glazed, and the body was very wide, allowing it to carry light Flak guns and small military vehicles. A single prototype was built and flown in 1941. The project was passed over in favour of the Gotha Go 242 The Gotha Go 242 was a transport glider used by the ''Luftwaffe'' during World War II. It was an upgrade over the DFS 230 in both cargo/troop capacity and flight characteristics. It saw limited combat action. There were multiple variants. Deve ....

DFS 228
The DFS 228 was a rocket-powered, high-altitude reconnaissance aircraft designed by the ''Deutsche Forschungsanstalt für Segelflug'' (DFS - "German Research Institute for Sailplane Flight") during World War II. By the end of the war, the aircraft had only flown in the form of two unpowered prototypes. Design and development Initial design of the DFS 228 was undertaken before the outbreak of war as a research aircraft, the DFS 54, aimed at developing a high-altitude escape system for sailplanes. The project was suspended by the commencement of hostilities, but was revived in 1940 when the ''Reichsluftfahrtministerium'' (RLM - "Reich Aviation Ministry") delivered the DFS with a requirement for a rocket-powered reconnaissance aircraft. The advantages of a sailplane for aerial reconnaissance included its silence, its low speed relative to the ground (allowing for higher-quality photography), and its potential ability to loiter above an area of interest. The project gave the DFS th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
