HyEnD is the boundary-pushing student rocketry team of the University of Stuttgart. In 2023, we set the European altitude record for student and amateur rockets as well as the world altitude record for hybrid propelled student rockets, achieving an altitude of 64 km with the launch of N 2 ORTH SN1 - just seven years after setting the same record at 32.3 km. Fueled by our shared enthusiasm for rocketry, we are continously looking to develop exciting new technologies and strive to pass down our knowledge to newer members... In June 2006 Hybrid Engine Development was founded by the student working group "STAR" at the University of Stuttgart, located at the Institute of Space Systems. Over several years, the group gained a high level of understanding of the processes in hybrid combustion chambers. Hybrid rocket engines were chosen because of their inherent safety. They use simple, safe, easily available, storable and manageable propellants like paraffin wax and nitrous oxide. They have..
