HAWA H 1 "Vampyr" was a German glider . It was designed by Arthur Martens , Friedrich Hentzen and Walter Blume - all of them former World War II pilots and at the time students of the Aviation Institute of the Technical University of Hanover - as part of the newly founded Akaflieg Hanover and built by the Hanoverian Waggonfabrik under the direction of Hermann Dorner . The design comes from Georg Madelung .
construction
The Vampyr is considered to be the ancestor of modern gliders, as it was the first to combine design features in an aircraft that shaped the design of performance gliders for decades. The lowest possible air resistance was the top priority when designing the aircraft. In contrast to the double-decker and boat designs still common at the time, the Vampyr had a closed hull. The wing was not braced except for two small auxiliary struts. The first single-spar construction of the wing with plywood-clad torsion nose (see Bredt's formula ) and ailerons as control surfaces, which was also adopted for powered aircraft, was groundbreaking .
use
In 1921 he first took part in the II Rhön competition on the Wasserkuppe. Arthur Martens covered 3580 meters in 5 minutes and 33 seconds in one flight. On September 5, he achieved a record flight of 7.5 km in 15 minutes and 40 seconds. In total, the Hanoverian prize money totaled 21,000 Reichsmarks.
A year later, the Vampyr was used in the same competition with a modified structure and set three new world records on August 18, 1922 with one hour and 6 minutes flight time, 8.9 km flight distance and 108 m cant, thus making the transition from gliding to Gliding. One day later, Friedrich Hentzen increased the flight time with the Vampyr to 2 hours 10 minutes, on August 21st even to 3 hours 6 minutes at 350 m cant.
A further development refined by Arthur Martens was the Strolch , which he flown at the IV Rhön Competition in 1923.
Whereabouts
The vampire was badly damaged in World War II and was in the basement of the Deutsches Museum in Munich. Cordes, a former director of Drägerwerke, took the initiative to restore the aircraft. The fuselage was restored in the Deutsches Museum, the wing, of which only the spar and fittings and fragments of the ribs remained, in the regional association workshop of the DAeC SH in Rendsburg- Schachtholm. The wing was returned to the Deutsches Museum in 1966 on the occasion of the German Aviation Day.
