It was not until 1955 that the Allies lifted the last research bans, which still covered many areas of aviation. Yet despite this new-found freedom the problem of a lack of space remained. Teaching and research had to be conducted at separate sites.
When the decision was made in 1956 to create a new university site at the Pfaffenwald area, building work began straight away. The first buildings were completed in 1959. Now the testing and teaching facilities (design studios, photo laboratories, etc.) could gradually be brought under one roof. Much of the work was done by students and lecturers on a volunteer basis.
Between 1960 and 1969 the most important buildings were constructed for the new institutes. This construction phase saw the creation of five institutes: Aerodynamics and Gas Dynamics; Aircraft Construction; Statics and Dynamics of Aeronautic and Astronautic Structures; Thermodynamics of Aeronautics and Astronautics; and Turbo Aircraft Engines.
