We are a student team from Technical University of Munich. We participate in REXUS mission 23. The REXUS program gives universities all over Europe the opportunity to perform experiments on sounding rockets. It is realized as a bilateral agreement between DLR and the Swedish National Space Board. The scheduled launch window is between 4th and 5th of March 2019 in Kiruna, Sweden.
Up to now the structural modules of a REXUS rocket are made of aluminum. A funding by DLR Space Administration allowed the TUM Chair of Carbon Composites (LCC) to develop a manufacturing strategy for a CFRP module.
Team TESOS uses this CFRP module to measure the temperature loads of the REXUS rocket in-flight within the laminate by fiber optic sensors.
