Inverted 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 Pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Junkers Ju 87
The Junkers Ju 87 or Stuka (from ''Sturzkampfflugzeug'', "dive bomber") was a German dive bomber and ground-attack aircraft. Designed by Hermann Pohlmann, it first flew in 1935. The Ju 87 made its combat debut in 1937 with the Luftwaffe's Condor Legion during the Spanish Civil War of 1936–1939 and served the Axis in World War II from beginning to end (1939–1945). The aircraft is easily recognisable by its inverted gull wings and fixed spatted undercarriage. Upon the leading edges of its faired main gear legs were mounted ram-air sirens known as ', which became a propaganda symbol of German air power and of the so-called ''Blitzkrieg'' victories of 1939–1942, as well as providing Stuka pilots with audible feedback as to speed. The Stuka's design included several innovations, including automatic pull-up dive brakes under both wings to ensure that the aircraft recovered from its attack dive even if the pilot blacked out from the high g-forces. The Ju 87 operated with c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DFS Reiher
The DFS Reiher (in English ''Heron'') was a single seat competition glider designed in Germany by Hans Jacobs and first flown in 1937. The type won the last two German Rhön gliding championships before the start of World War II. Six were factory produced. Design and development In 1935 Hans Jacobs had been asked by Alexander Lippisch to become chief designer of sailplanes at the nationalised Deutsche Forschungsanstalt für Segelflug (DFS) at Darmstadt, after the closure of the RRG (Rhön-Rossitten Gesellschaft) on the Wasserkuppe in 1933. In 1936 there was more recognition of the need for fast gliders with high wing loading and low camber to fare better in competitions by moving quickly between strong thermals; the hope was that camber-changing flaps would enhance lift in the climb. The Reiher was Jacobs' attempt to build these qualities into a new sailplane, using all the DFS design and prototype production facilities and skills. It was an all-wood aircraft with a mid-mou ...

DFS Kranich
The DFS Kranich is a type of German glider. It was developed by Hans Jacobs for the Deutsche Forschungsanstalt für Segelflug (DFS). History Series production of the Kranich (Crane) took place in the aircraft division of Karl Schweyer AG in Mannheim. The two-seater was, in its version 2, the most widely built two-seat glider in Germany from 1935 to 1939. Several hundred examples were built; exact numbers are not known. On 11 October 1940 Erich Klöckner in a Kranich achieved the record height in a glider of 11,460 m (37598 ft). Because it occurred in wartime, the altitude record was not recognized by the Allied occupying powers, and Klöckner only received official recognition by the Fédération Aéronautique Internationale (FAI) in the late 1990s.aerokurier magazine 1/1999: Erich Klöckners Vorstoß zur Tropopause, Motor Presse 1999 This record height was only exceeded ten years after the flight by the American Bill Ivans during a similar scientific program in the Sierra Ne ...

DFS Habicht
The DFS ''Habicht'' (German: "Hawk") is an unlimited aerobatic sailplane that was designed in 1936 by Hans Jacobs with support provided by the Deutsche Forschungsanstalt für Segelflug. Four planes were made available for the Olympic Games of 1936, where the maneuvers of the Habicht over and literally inside the Olympic stadium enthralled spectators. The flight qualities of the Habicht were praised by pilots, including Hanna Reitsch. It participated in many airshows abroad before the war, including the 1938 National Air Races in Cleveland, Ohio.Reitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, Modified versions of the Habicht, dubbed the Stummel-Habicht ("Stumpy Hawk"), were used to train pilots to fly the Messerschmitt Me 163 Komet rocket-powered fighter. Trainees included students from the Hitler Youth Glider Schools. The Me 163 was designed to use its entire load of rocket fuel to reach combat altitude of approximately , before return ...
