gliding organisation during his summer vacations. He teamed up his spare time with his elder brothers Wolfgang and Heinrich to construct experimental flying machines. As their designs became more ambitious, in 1932 Ulrich and Wolfgang started to take lessons to qualify as Glider pilots, using the knowledge gained to develop more sophisticated flying machine models of their own design. One product of their enthusiasms during these years was a basic glider which the brothers constructed in 1930/31. During the two years it took, the project was reported to have cost the brothers approximately 500

It was purchased in November 1931 by the "Vienna Academic Flyers' Group" (''"Akademische Fliegergruppe"''). In 1936 Ulrich Hütter switched to the College of Technology (subsequently renamed) in

to study aeronautical technology, and emerging two years later with his degree in the subject. Meanwhile, in July 1932 Ulrich and his brother Wolfgang had joined the NSDAP (party), a move which presumably appeared career enhancing at the time, although it would cause problems for him after 1945. Hütter received his doctorate in 1942 from the Vienna College of Technology. His work, supervised by Prof. Dr.-Ing, Eugen Feifel, was submitted as "a contribution to the design fundamental for wind power plants". It expounded what subsequently became known as "Hütter's wind rotor theory". Between 1939 and 1943 he was actually living not in

College of Technology. In May 1945 war ended and he was interned, but the duration of his detention was reportedly brief. As a former party member he underwent a denazification process, during the course of which he was classified as a "Mitläufer" (''loosely, one who had run with the pack'') rather than an instigator or perpetrator of Nazi atrocities, and was accordingly permitted to set himself up as a freelance engineer and specialist consultant on wind energy at the home of his wife's parents in Kirchheim, just outside Stuttgart. In some ways it was a question of starting again, but despite the difficulties of the post-war years, Hütter seems to have little difficulty in finding work and being well paid for it.

Under more normal circumstances it would have been unusual for someone intending to pursue a career as a universities level teacher in Germany to wait till they were 46 before obtaining a habilitation degree, but Hütter's career path towards the universities sector had been far from direct, and had included the twelve Hitler years.

In 1959 Hütter accepted an extraordinary professorship in the context of his appointed as head of the college's newly founded Department of Flight Physics. As the size and scope of the department expanded, Hütter's status and seniority grew correspondingly, together with his international reputation. In 1965 Ulrich Hütter was appointed to an ordinary (i.e. full) professorship, with his own teaching chair at University of Stuttgart">the college. The final fifteen years of his professional career were increasingly focused on teaching and promoting wind turbine technology, both in Europa and further afield. His turbine designs increasingly attracted interest internationally, notably in South Africa, Abyssinia, Spain, Italy and France. Hütter not infrequently travelled to wind-energy construction sites in person, in order to be able to advise on (and learn from) issues arising with new installations. He also received and accepted invitations to deliver lectures and provide consultations in Sweden and North America. He appeared before the US House of Representatives in the context of hearings on wind energy, though it was probably more as a result of his lucid published work on the topic that his ideas exercised significant influence on the early US wind energy programmes and on subsequent developments in the sector, both in the
