  • ROTOR STAGE
    Publication number: 20180073377
    Abstract: A boundary layer Ingesting (BLI) fan system operates with a highly non-uniform flow field that propagates through the fan stage. The fan stage suffers from hub separations, increased wake thicknesses and casing losses. These loss sources can be reduced or eliminated by varying the inlet metal angles and/or chordal lengths of the downstream fan stators.
