The focus of the faculty's work is aligned with the BTU's research field of "Energy efficiency and sustainability". Future fields are highly efficient, modern propulsion systems as well as energy- and resource-saving, sustainable product development and production. This includes the already extremely successful field of aircraft engine technology with the Rolls-Royce UTC "Multidisciplinary process integration" as well as research into efficient, safe and low-emission aircraft engines and the corresponding production and IT processes. In addition, the focus is on energy conversion and management in the development of vehicles, including energy-efficient lightweight solutions. Here, the focus is on MMD (multi-material design) solutions with fiber composites and metals as well as the manufacturing technologies and processes required for this. This includes a multidisciplinary, integrated approach that takes a holistic view of relevant problems.
