Wolfgang Hütter (designer)

Wolfgang Hütter (born October 2, 1909 in Vienna ; † April 3, 1990 in Göppingen ) was an Austrian - German engineer.

Life

Born in Vienna on October 2, 1909, Hütter grew up in Salzburg . Here he began studying mechanical engineering and designed the first aircraft such as the IMI flying wing . The wooden plane built together with his brother Ulrich did not fly, the HT 23 glider remained in the design stage. In 1934 he began flight tests on the Hütter H 17 , which he had designed with his brother, on the Gaisberg near Salzburg. In 1936 the H 28 followed , in 1938 the simplified version of the H 28 II and in 1939 the H 28 III with an enlarged span from 12 to 13.50 meters. The H 30 , designed for wooden shell construction during the Second World War and constructed after 1945, was finally built by Ursula and Eugen Hänle by replacing many assemblies with GRP constructions . In the early 1960s, he and Eugen Hänle constructed the H 301 dragonfly and designed its wing profile . As a diploma thesis in his studies, which he continued at the Technical University of Stuttgart with Professor Georg Madelung , he designed the two-seater school glider Göppingen Gö 4 with staggered seats and double steering while working for Schempp-Hirth Flugzeugbau in Kirchheim in 1937 . In 1938, together with Ulrich Hütter, he developed the air brakes that became known as the Schempp-Hirth valve . He headed his Hütter GmbH, founded in 1939 for the construction of the twin-engine long-range reconnaissance aircraft Hütter Hü 211 , until April 30, 1944 and then became chief designer of Wolf Hirth's "Versuchsbau Teck" in Nabern . After he had already carried out tests to determine human performance in the 1930s and, for example, had built a bicycle ergometer in 1936, he designed and built the HVS muscle- powered aircraft together with Franz Villinger and Wilhelm Schüle from 1974 for the Kremer Prize .

Some of his designs were widely used: In addition to the Schempp-Hirth flaps, these were the trailing arm drive used in 1944 for the rudder flaps of the Hü 211 and the tongue-and-fork wing connection of the H 30.

He died on April 3, 1990 in Göppingen.
