  • Berechnungsmodell zur Widerstandsbeeinflussung nicht-idealer Riblets auf Verdichterschaufeln 
    Lietmeyer, Christoph Jan (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2013)
    Vor dem Hintergrund, die CO2-Emissionen und die Betriebskosten von stationären Gasturbinen und Flugtriebwerken zukünftig signifikant zu reduzieren und dadurch politisch gesetzte und ökonomisch gebotene Ziele zu erreichen, ...
  • Grinding of riblets with "beaver tooth" multi-layer tools 
    Hockauf, Rolf; Asadi, Esmail; Denkena, Berend; Grove, Thilo; Wurz, Marc Christopher (Amsterdam : Elsevier B.V., 2018)
    To reduce friction in turbo machinery components, riblets are induced on compressor blades or pump impellers. Here, the grinding process enables a higher productivity in machining of riblet structures compared to knurling, ...
  • Prediction of the Principal Stress Direction for 5-axis Ball End Milling 
    Böß, Volker; Grove, Thilo; Denkena, Berend; Mücke, A.; Nespor, D. (Amsterdam : Elsevier, 2016)
    While regenerating damaged components, e.g. compressor blades, the removal of excess weld material called re-contouring often determines the surface integrity including the residual stress state. A load-specific residual ...
  • Surface roughness of real operationally used compressor blade and blisk 
    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 ...
  • Tools and Strategies for Grinding of Riblets on Freeformed Compressor Blades 
    Denkena, Berend; Grove, Thilo; Krawczyk, T. (Amsterdam : Elsevier BV, 2016)
    A major goal in the design of turbomachinery is the increase of efficiency. To attain this increase, the flow losses must be reduced. A substantial proportion of the losses is generated by skin friction between compressor ...
