  • Aerodynamic damping of composite UHBR fans under the consideration of acoustic intake reflections 
    Gößling, Jan; Seume, Joerg R.; Flüh, Jan Peter; Paletta, Nicola; Eggers, Torben; Friedrichs, Jens; Natale, Nunzio (New York, N.Y. : The American Society of Mechanical Engineers, 2022)
    Steadily rising regulations and demands on aeroengines require the continuous reduction of CO2 emissions. Among other factors, particularly the weight reduction of the engine as well as synergetic engine-airframe integration ...
  • Composite UHBR fan for forced response and flutter investigations 
    Eggers, Torben; Friedrichs, Jens; Goessling, Jan; Seume, Joerg R.; Natale, Nunzio; Flüh, Jan Peter; Paletta, Nicola (New York, N.Y. : The American Society of Mechanical Engineers, 2021)
    In the CA3ViAR (Composite fan Aerodynamic, Aeroelastic, and Aeroacoustic Validation Rig) project, a composite lowtransonic fan is designed and tested. The aim is a scaled ultrahigh bypass ratio (UHBR) fan with state-of-the-art ...
  • Conceptual design of operation strategies for hybrid electric aircraft 
    Hoelzen, Julian; Liu, Yaolong; Bensmann, Boris; Winnefeld, Christopher; Elham, Ali; Friedrichs, Jens; Hanke-Rauschenbach, Richard (Basel : MDPI AG, 2018)
    Ambitious targets to reduce emissions caused by aviation in the light of an expected ongoing rise of the air transport demand in the future drive the research of propulsion systems with lower CO2 emissions. Regional hybrid ...
  • Design Decisions for a Powertrain Combination of Electric Motor and Propeller for an Electric Aircraft 
    Keuter, Ralf Johannes; Kirsch, Bastian; Friedrichs, Jens; Ponick, Bernd (New York, NY : IEEE, 2023)
    For the sizing of an electric motor, the diameter and length of the installation space are important parameters that significantly influence and limit the characteristics of the electric motor. From an aerodynamic point ...
  • A study on electrofuels in aviation 
    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 ...
  • 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 ...
  • Virtual process for evaluating the influence of real combined module variations on the overall performance of an aircraft engine 
    Goeing, Jan; Seehausen, Hendrik; Stania, Lennart; Nuebel, Nicolas; Salomon, Julian; Ignatidis, Panagiotis; Dinkelacker, Friedrich; Beer, Michael; Berend, Berend; Seume, Joerg; Friedrichs, Jens ([Zug] : GPPS, 2023)
    The effects of real combined variances in components and modules of aero engines, due to production tolerances or deterioration, on the performance of an aircraft engine are analysed in a knowledge-based process. For this ...
