Biography:
Andreas Rittweger since February 2014 professor of aerospace engineering at the Department of Production Engineering at the University of Bremen. He is also the new director of the Institute for Space Systems of the DLR (German Aerospace Center). Rittweger studied at the RWTH Aachen Aviation and aerospace engineering and a PhD at the Institute for Lightweight on the calculation of anisotropic shell structures. In the aerospace industry, he gained experience in the development of the Ariane 5 rocket, initially in Bremen, later in Les Mureaux near Paris. There, he managed the spacecraft engineering, among others responsible for the mechanics, the thermal budget and the construction of the Ariane 5 rocket and future support systems. In Bremen Rittweger will study at the Institute of Space Systems Concepts future spacecraft and space missions, develop scientific small satellites and planetary landers and build and to participate in the exploration of critical system-related technologies for future transport systems, landing and science missions.
