... of harmonics ( H  =   10) to obtain accurate results for μ ≥ 0.2 . While such results could be of interest from an academic standpoint, it goes beyond the scope of this article as typical friction coefficients in such blade-tip/casing contacts is usually less than 0.15. Nonetheless, even with H...

... an opportunity for the direct comparison of recently developed methodologies relative to nonlinear vibration phenomena in turbomachines, including rubbing events and blade-tip/casing contacts. To this end, the paper also contains original results for some of the most emblematic NASA blades, with an emphasis...

...Yann Colaïtis; Alain Batailly In this study, a frequency-domain approach based on the harmonic balance method coupled to a predictor-corrector continuation algorithm is implemented for the qualitative analysis of blade-tip/casing contacts in aircraft engines. Unilateral contact and dry friction...
