Development of new lightweight construction concepts for aircraft turbines

(Kopie 3)

Project Leader: Prof. L. Wagner (Dr.Eng)

Funding period: 07/2012 – 12/2015
Funding body: BMBF

Within a joint project initiated by the Federal Ministry for Education and Research (Bundesministerium für Bildung und Forschung, BMBF), within the scope of the Material Innovations for Industry and Business (Werkstoffinnovationen für Industrie und Gesellschaft, WING) program, the Institute for Material Engineering and Material Technology is to receive funding in the amount of €760,000 for the next 3 years. Within the joint project, with total funding amounting to around €4 million, 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.

Through the use of titanium-based multi-orbital friction-welded tool pairings, a noticeable cost reduction should be realised in comparison to previous production methods. The new manufacturing process also enables the implementation of innovative cooling concepts for the turbines, which enables and increase in the turbine inlet temperature and thus increases the efficiency of the engine. In particular, this approach also seeks to meet the requirements regarding the reduction of the specific fuel consumption (SFC) and of the emission of pollutants. Within the context of the BMBF project, the IWW is also to receive a multi-orbital friction-welding system for the planned joint tests on the hybrid connections consisting of various titanium and nickel alloys.
