WARR (German: Wissenschaftliche Arbeitsgemeinschaft für Raketentechnik und Raumfahrt, English: Scientific Workgroup for Rocketry and Space Flight) is a student group at the Technical University of Munich (TUM). Founded in 1962 by , its initial objective was to compensate for TUM’s lack of an institute astronautics. In 1966, the university established such an institute, allowing WARR to focus on the practical aspects of space flight, as opposed to the theoretical.
Today, the objective of the student group is to enable students from various fields of study to apply their theoretical knowledge and gain practical experience.
One of WARR’s greatest achievements to date is the construction and launch of the first German hybrid rocket called Barbarella, on 12 March 1974, which is now displayed in the German Museum in Munich.
Existing since the foundation of WARR in 1962, the department for rocketry is the oldest project group of WARR. With the launch of the first German hybrid rocket in 1974, WARR achieved its first major success, which was promptly followed by the construction of multiple test engines. In 2009 the development of its next rocket began, called WARR-Ex2, powered by the in-house developed hybrid engine HYPER-1 with solid HTPB fuel and nitrous oxide as oxidizer. The rocket was successfully launched on 20th of May 2015 from the missile base CLBI on the Atlantic coast of Brazil and reached a maximal altitude of approximately 5 km. Even before the launch of WARR-Ex2, WARR had begun working on its successor, WARR-Ex3, as part of project STERN (STudentische Experimental-RaketeN) (German abbreviation for “student experimental rocketry”), organized and financed by the German Aerospace Center. As the given objectives of STERN were already reached within WARR-Ex2, it was decided to build a larger rocket, which should break the European altitude record for student rockets, counting 21.5 km for now. To reach this goal, the WARR-Ex 3 will use liquid oxygen instead of nitrous oxide, while maintaining the use of HTPB. The launch of WARR-Ex3 is currently planned for the beginning of 2017.
