Compressor stator vane with variable pitch having an extended fillet

摘要

An example variable stator vane assembly (29) includes at least one button (38), a vane airfoil (40) adjacent to the button (38), and a fillet (52) defined between the button (38) and the airfoil (40). In one example, the fillet (52) defines a constant radius and extends beyond the button (38) at least greater than a distance of 60% of a length of an overhang portion (58) of the vane airfoil (40).
