Abstract
The present disclosure is generally related to a vane assembly for an open fan engine having a rotor and a stator. The vane assembly is a plurality of vanes each arranged about the stator. Each of the vanes of the vane assembly has a leading edge (LE) with a leading edge angle (LEA). A combination of aircraft angle of attack, sideslip, and upwash due to lifting bodies can create a flow angularity into the engine. The leading edge angle (LEA) of each of the vanes varies depending upon the circumferential location about the stator so that the impact on the flow angularity into the engine is reduced or increased in different circumferential regions.
