who we are

Dipl.-Ing. (FH) Tobias Ruhe M.SC.

Tobias Ruhe, born 1976, studied Aerospace Engineering at the University of Applied Science Aachen – graduated 2005 as Dipl.-Ing. (FH). He did his diploma thesis at the RWTH Aachen University about investigations of an advanced leak identification method for the AMS-02 particle detector on board the International Space Station (ISS). From 2005 until 2009 he worked as A380 Change Manager at Airbus Deutschland GmbH, Hamburg. With his passion in space technologies he switched to the German Aerospace Center (DLR), Facility of Space Operations and Astronaut Training, Department: Mobile Rocket Base (MORABA) at Oberpfaffenhofen, Munich. Besides in 2016, he received his Master’s Degree of Science in Aerospace Systems Engineering from the University of German Armed Forces Munich. After 8 years of conducting international sounding rocket projects (flight systems), Ruhe moved forward to the Institute of Structures and Design, Department: Space System Integration (RSI) at DLR base Stuttgart. There, he is designing aerodynamic, thermal-stable, hypersonic flight and re-entry vehicles since 2017.

Dipl.-Ing. (FH) Henning Elsäßer

Henning Elsäßer, born in 1982 in Fassberg, Germany, received his Diploma in Aerospace Engineering from the University of Applied Science Aachen in 2007 (Dipl.-Ing. FH). Beside the study, he gained first practical experience in optimizing and manufacturing of Ultra-light Aircrafts (ULA) in Carbon/Glas Fibre Reinforced Plastic (CFRP/GFRP) materials at Wolfgang Dallach Flugzeugbau GmbH. In 2007 he switched to DLR Stuttgart, Institute of Structures and Design, Department of Space System Integration and was involved in the development of cryogenic Ceramic Matrix Composites (CMC) and CFRP combustion chambers. Since then, he is concentrated in design and testing of cost effective thermo-mechanical loaded structures, especially structures for re-entry and hypersonic flight experiments combining all kind of CMC´s, CFRP and ablative materials. Using this experience in hi-performance materials and hybrid designs, 2010, Elsäßer started to develop sounding rocket fins for the Brazilian VS40 launcher system. Thus, he refers to more than 10 years of successful experiences in hypersonic and sounding rocket fin designs, tests and flight missions.
