Funding body: BMBF
The Institute of Materials Science and Engineering is receiving funding of around €760,000 over the next 3.5 years from the Federal Ministry of Education and Research (BMBF) as part of the Materials Innovations for Industry and Society (WING) program. Rolls-Royce Deutschland, Thyssen Krupp VDM, Otto Fuchs KG, Dyconn GmbH, the University of Erlangen-Nuremberg and the IWW are working together on the development of new lightweight construction concepts for aircraft turbines in the joint project with total funding of around €4 million.
The use of multiorbital friction-welded material pairings based on titanium and nickel should lead to a noticeable cost reduction in engine construction compared to the previous production route. The new production route also enables the implementation of innovative cooling concepts for the turbine, which allows an increase in the turbine inlet temperature and thus increases the efficiency of the engine. In particular, this approach also meets the requirements for reducing specific fuel consumption (SFC) and pollutant emissions. As part of the BMBF project, the IWW will also receive a multiorbital friction welding system for the planned joining tests on the mixed joints made of various titanium and nickel alloys.
