Innovative low noise fan stator technologies for 2030+ powerplants

Low noise fan stator solutions are key technological components for Future Generation UHBR to ensure continuous aircraft noise reduction while addressing low Fuel Burn and associated C02 targets. The objective is to mature innovative approaches such as passive flow control OGV design as well as soft (treated) stator options to overcome challenging UHBR fan module specificities (reduced rotor – stator spacing, reduced OGV count). Efficient stator concepts are to be designed. Experimental validation of most promising solutions will be performed on a large scale aero and acoustic fan rig while exploring in parallel new manufacturing processes to address engine integration constraints. The maturation of the solutions will be focussed on UHBR application, but results could have benefits on BLI or Open Rotor powerplant systems.
