Prediction of the Acoustic Reflection in a Realistic Aeroengine Intake With Three Numerical Methods to Analyze Fan Flutter

Thomas Bontemps, Stéphane Aubert, Maxime de Pret
Journal: Journal of Turbomachinery
Article Type: Research Papers
J. Turbomach. October 2021, 143(10): 101016.
Paper No: TURBO-21-1011
DOI: https://doi.org/10.1115/1.4051113
Published Online: July 5, 2021
...Thomas Bontemps; Stéphane Aubert; Maxime de Pret For a particular range of frequencies, an acoustic coupling between the fan and the air intake can modify fan stability regarding flutter. Previous works have shown that characterizing the reflection on the intake opening might be a crucial element...
