Supporting implementation of 2030+ UHBR low noise fan technology solutions through enhanced modeling capabilities

Topic description

Specific Challenge:

The design of innovative low fan noise technologies for next generation UHBR engines is highly conditioned by the accuracy of aeroacoustic modelisations and related design tools. Recent advances in numerical techniques, allowing to foresee more integrated approaches associated with more realistic high fidelity aeroacoustic simulations will be considered to further guide UHBR Low fan noise design and noise reduction technologies concepts (such as fan frame liners and low noise OGV concepts). The aim of the topic is to develop new postprocessing solutions to be applied on numerical/experimental results to further identify 2030+UHBR fan noise sources components/mecanisms and improve noise status. The maturation of the modelling solutions will focus on UHBR application with a more integrated “under the wing” configuration, with results extrapolated to BLI power plant systems integration.
