  • VFS Dedicates Focke's Wind Tunnel As Vertical Flight Heritage Site
    VFS Dedicates Focke’s Wind Tunnel as Vertical Flight Heritage Site By Berend van der Wall n Sept. 15, the Vertical Flight Society held its Vertical Flight Heritage Site Award ceremony at the Focke Wind Tunnel Oin Bremen, Germany. This was the 12th site recognized since VFS began the program in 2013, which recognizes and helps preserve the most important vertical flight historical sites around the world. The Focke Wind Tunnel was built by Prof. Dr. Henrich Focke, the famous German aeronautical pioneer and aircraft designer, and was his last research laboratory. Construction of the wind tunnel began immediately after his retirement in 1961 and it was finished in 1963. Interestingly, the wind tunnel building had been the workshop of a carpenter who had built the wind tunnel model of the first Focke-Wulf A 16 light transport aircraft in 1923. Historic Background Focke became interested in rotating-wing aircraft in 1932. The Steffen (right) and van der Wall (left) unveil the VFS Focke-Wulf company built 40 Cierva C.30 Autogiros under license plaque at the Focke Wind Tunnel. (Photos courtesy of in Germany as the Fw 30 Heuschrecke (“Grasshopper”). His Fw 61 the author) was arguably the first practical helicopter in the world. Its maiden flight took place in 1936 at Bremen Airport and later broke all existing world records. Before VFS started its Vertical Flight Heritage Sites program in 2013, the Society was supporting a program by the American Institute of Aeronautics and Astronautics (AIAA). VFS members successfully nominated several helicopter and VTOL sites for their program, including Bremen Airport, recognized in 2011 for its historical significance in aviation.

I don't believe you, you're kidding me.“ Frühe Fluggeräte, ob schwerer oder leichter als Luft, bestanden aus Materialien, die uns heute im besten Fall als ungeeignet erscheinen. Bambus und Stoff weckten aber auch das Misstrauen der frühen Flugzeugbauer und -nutzer. Das revolutionäre Technologiesystem Flugzeug sollte von jeher aus den modernsten Materialien bestehen, ganz gleich ob sie immer wirklich die geeignetsten waren. Dieses Dogma hat bis heute nichts an Gültigkeit verloren. Und bis heute verursacht dieser Zwang zu den aktuellsten Materialien oft mehr Probleme als er löst. Das Beispiel Flugzeugbau bietet interessante Antworten auf die Frage, warum sich Technologien durchsetzen bzw. eben nicht durchsetzen.

  • Legendäre Me 262
    Der Luftkrieg im 2. Weltkrieg Parallel wurden natürlich auch Militärflugzeuge weiterentwickelt, konstruiert, neue geschaffen und als 1939 der zweite Weltkrieg beginnt, stehen bei allen kriegführenden Mächten sehr, sehr viele Flugzeuge zur Verfügung, nicht nur von der Anzahl her, sondern auch von ihren Einsatzmöglichkeiten. Es sind vor allem die Bombenflugzeuge aller kriegführenden Länder, die uner- messliches Leid über die zivile Bevölkerung bringen und auch furchtbare Zerstörung der Wohnbereiche anrichten. Man glaubte mit solchen Verfahren die Gegner schneller besiegen zu können ("morale bombing"). Diese beiden Vitrinen, die Sie hier sehen, zeigen einmal den Einsatz deutscher Bombenflugzeuge, die bei der Bekämpfung militärischer Ziele natürlich auch sehr viele zivile Objekte zerstört haben (das wird heute gern von den kriegführenden Mächten als "Kollateralschaden" bezeichnet), während des Westfeldzuges gegen die Niederlande, Belgien, Frankreich und in der Luftschlacht über England 1940/41. Die andere Vitrine zeigt aber auch den zielgerichteten Einsatz amerikanischer und englischer Bombenflugzeuge gegen deutsche Großstädte, der - wissen- schaftlich fundiert und begleitet - mit großer Effektivität und Grausamkeit geführt wurde. Auch die nächtliche Luftabwehr mit Flak und Nachtjägern über dem Reich wird hier dargestellt. Am Ende des 2. Weltkrieges waren 66 deutsche Großstädte zerstört, über Dresden wird immer noch diskutiert. Das kommt dabei heraus, wenn unverantwortlich mit der Macht hantiert wird. Die Vitrinen zeigen als Beispiele die Städte Hannover und Dresden, aber auch die von London und Coventry durch die deutsche Luftwaffe verur- sachten Schäden. Auf der anderen Seite sehen Sie verschiedene anglo- amerikanische Fliegerbomben, die als Blindgänger in Hannover und umzu ausgegraben wurden. Und selbst was Sie am Ende sehen, ist nicht eine Litfaßsäule sondern eine englische Fliegerbombe mit ca.

  • Short History of Brazilian Aeronautics
    Proceedings of the 11th Brazilian Congress of Thermal Sciences and Engineering -- ENCIT 2006 Braz. Soc. of Mechanical Sciences and Engineering -- ABCM, Curitiba, Brazil,- Dec. 5-8, 2006 Paper CIT06-0458 A Brief History of Brazilian Aeronautics Bento Silva de Mattos Technological Institute of Aeronautics – São José dos Campos – São Paulo - Brazil [email protected] Abstract. The history of aeronautics is the history of the technological development spiced by the enterprising spirit of aviation pioneers. The flight revolution was largely a product of technology and not so much of science. Its practitioners followed the tradition of the craftsmen and technicians who, awakened by the experimental method of Sir Francis Bacon and others, were the proto-engineers of the great expansion of technology and engineering that happened from the time of the Industrial Revolution onwards. Its first great accomplishment was the re-invention of lighter-than-air flight in 1783. Some time before the Brazilian Jesuit Bartolomeu de Gusmão make flew an unmanned small balloon in Portugal. By the mid-1790’s, the balloon had already been turned to practical benefit, as an observation system; it appeared as a scientific lifting platform shortly afterwards. The quest for steerable flight led to the creation of practical, small airships by the end of the 19th century, and the larger rigid airship appeared at the beginning of the 20th century, almost simultaneously with the appearance of the airplane. An overview of milestone events that marked the history of aeronautics worldwide is presented in its early days. The major achievements by the Brazilian Santos-Dumont are also described and analyzed as well as the major events in the Brazilian Aeronautics history.

Das sind Gründe genug, den Werdegang und das Schicksal der Focke-Wulf „Ente“ näher zu betrachten. Die Vorgeschichte Die Arbeiten der Brüder Focke am Entenproblem reichen zurück bis in das Jahr 1907. Damals begannen Wilhelm und Henrich Focke, Entenmodelle zu bauen und sie frei fliegen zu lassen. Im Laufe der Versuche erkannten die Brüder bereits als grundlegende Voraussetzung für die Längsstabilität eines Entenflugzeugs, daß der kleinere Vorderflügel (das Höhenleitwerk) einen stärkeren Einstellwinkel besitzen muß als der große Hauptflügel, der Schwerpunkt der Maschine vor dem Hauptflügel liegen muß. Dieses Enten-Grundkonzept ließ sich Wilhelm Focke 1908 patentieren (DRP Nr. 238542 vom 18.12.08 „Drachenflieger mit hinter- einander liegenden, verschieden großen Tragflächen“). Den Modellversuchen schloß sich der Bau eines „lebensgroßen“ Entenflug- zeugs an, das mit finanzieller Unterstützung von Dr.
