Alexander Polidar, M.Sc.

Alexander Polidar studied Mechanical Engineering at the Technical University of Darmstadt and the KTH Royal Institute of Technology in Stockholm. He specialized in Aerospace engineering and fluid mechanics. During his Master’s thesis, he designed an oxidizer-rich preburner for a staged combustion rocket engine at the company Rocket Factory Augsburg. With his experimental research, he aims to advance the flexibility of liquid-oxygen/methane (LOX-methane) rocket engines.
