Potential of additively manufactured particle damped compressor blades: A literature review

Niedermeyer, Jens; Ehlers, Tobias; Lachmayer, Roland (Amsterdam [u.a.] : Elsevier, 2023)

The high-cycle fatigue of compressors significantly impacts the lifetime of aircraft engines. Excitations in resonance lead to early blade fractures; therefore, vibration reduction measures for blades must be taken. ...
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 ...
