International audience; Entropy noise is produced when temperature fluctuations (entropy spots) are accelerated by the mean flow, through a nozzle or a turbine stage for instance. When it propagates outside the engine it contributes to community nois

International audience; Modern UHBR (Ultra High Bypass Ratio) aeroengines are characterized by reduced fan speeds and very short asymmetric intakes, so that the mean flow entering into the nacelle is no more uniform along the azimuthal direction (par
