The German Aerospace Congress 2026 took place in Aachen from 8 to 10 September. HYTRAC's contribution addressed the preserved technological foundation of Sänger II and perspectives for reactivation.

The central question was how historical systems and propulsion knowledge can be reconstructed, digitized and reassessed under present-day conditions. The approach aims to establish a sound basis for future research and demonstrator programmes.

Dr.-Ing. Helmut Warth was the presenting author. Co-authors were Rolf Kramer, Joachim Kretschmer and Dr.-Ing. Guido Kurth.
