  • Goldmann, Andreas; Sauter, Waldemar; Oettinger, Marcel; Kluge, Tim; Schröder, Uwe; Seume, Jörg R.; Friedrichs, Jens; Dinkelacker, Friedrich (Basel : MDPI AG, 2018)
    With the growth of aviation traffic and the demand for emission reduction, alternative fuels like the so-called electrofuels could comprise a sustainable solution. Electrofuels are understood as those that use renewable ...
  • Denkena, Berend; Flöter, F. (Amsterdam : Elsevier BV, 2012)
    In the re-contouring process of aircraft engine components, the unknown geometry and inhomogeneous material properties of the workpiece are major challenges. For this reason a new repair process chain is supposed which ...
  • Alfred, Irene; Nicolaus, Martin; Hermsdorf, Jörg; Kaierle, Stefan; Möhwald, Kai; Maier, Hans Jürgen; Wesling, Volker (Amsterdam : Elsevier B.V., 2018)
    Components in aircraft engines and gas turbines are exposed to extreme conditions in order to increase performance and efficiency of the overall engine, hence there is an increasing need for cost-effective and time-efficient ...

  • Denkena, Berend; Boess, V.; Nespor, D.; Rust, F.; Floeter, F. (Amsterdam : Elsevier, 2014)
    Re-contouring in the repair process of aircraft engine blades and vanes is a crucial task. Highest demands are made on the geometrical accuracy as well as on the machined surface of the part. Complexity rises even more due ...
  • Rottwinkel, Boris; Nölke, Christian; Kaierle, Stefan; Wesling, Volker (Amsterdam : Elsevier B.V., 2014)
    The formation of cracks in single crystal (SX) turbine blades is a common problem for aero-engines. To repair cracks, which are located under the tip-area, a new method is to clad with single-crystal-technology. This ...
  • Mueller, J.-K.; Bensmann, A.; Bensmann, B.; Fischer, T.; Kadyk, T.; Narjes, G.; Kauth, F.; Ponick, B.; Seume, J.R.; Krewer, U.; Hanke-Rauschenbach, R.; Mertens, A. (Basel : MDPI AG, 2018)
    Active high-lift systems of future civil aircraft allow noise reduction and the use of shorter runways. Powering high-lift systems electrically have a strong impact on the design requirements for the electrical power supply ...
  • Urbano, Jose; Golowin, Andrej; Löhnert, Stefan; Bestle, Dieter (Les Ulis : EDP Sciences, 2018)
    Currently, prediction of crack initiation by corrosion pits is only possible by assuming regular geometrical shapes, such as semi-spheres or semi-ellipsoids. Moreover, typical fatigue life diagrams associate the crack ...
  • Denkena, Berend; Dahlmann, Dominik; Floeter, F.; Bruehne, T. (Amsterdam : Elsevier, 2014)
    Difficult-to-machine materials are still challenging the production industry. Examples are highly complex components of aircraft engines. Alongside innovative processes, also improved machine tool components are helping ...
  • Gilge, Philipp; Kellersmann, Andreas; Friedrichs, Jens; Seume, Jörg R. (London : SAGE Publications Ltd., 2019)
    Deterioration of axial compressors is in general a major concern in aircraft engine maintenance. Among other effects, roughness in high-pressure compressor reduces the pressure rise and thus efficiency, thereby increasing ...
