The Space Team Aachen Hybrid Rocket, also called 'STAHR', is set to reach an apogee of 12 km. It is being designed and launched as part of the STERN (STudentische Experimental RaketeN) program of the German Aerospace Center (DLR), whose aim is to support student teams in the development of suborbital rockets. STAHR is set to launch in 2024 from Esrange, Sweden.
STAHR will be the first rocket of Space Team Aachen with a self-developed hybrid engine, which will be designed to reach an average thrust of 4kN. The rocket’s body will be manufactured out of carbon fiber using state-of-the-art winding, 3D printing techniques, and split mold manufacturing. The tank, necessary to store up to 30 kg of oxidizer at a pressure above 60 bar, will also be manufactured in-house out of CFRP, enclosing an aluminium liner. The rocket’s avionics, which monitor and gather its flight and engine data, are designed redundantly, using both student-developed and commercially available flight computers. The recovery system, which shall guarantee the rocket's safe return to the ground, will feature a dual parachute system consisting of a drogue and main chute. Unlike our previous rockets, the parachutes will not be bought but rather manufactured by students with support from our partner institutes of RWTH Aachen University.
