摘要：
A fan of an aircraft engine is provided with a rotating fan rotor for feeding air aftward as a spiral flow and a stator vane for rectifying the spiral flow to be an axial flow. The fan stator vane is provided with a hub end portion extending radially relative to a rotating axis of the fan rotor and a tip end portion leaning toward a suction side. Leading edges of the hub end portion and the tip end portion have sweepback angles of from 27 degrees to 33 degrees relative to a radial direction defined by the rotating axis.
