1. A compressor bleed slot apparatus, comprising:
an annular compressor casing;
a blade row mounted for rotation about a centerline axis inside the compressor casing;
a bleed slot passing through a forward section of the compressor casing, wherein the bleed slot is bounded by inboard and outboard walls defined within the compressor casing, the bleed slot extending along a slot axis, at least a portion of the bleed slot lying within an axial extent of the blade row;
an array of struts interconnecting the inboard and outboard walls; and
an annular supplemental flange extending radially outward from the outboard wall of the compressor casing, wherein at least a portion of the annular supplemental flange is axially positioned within an axial extent of the bleed slot, wherein the annular supplemental flange does not provide a connecting function of the compressor casing, wherein the annular supplemental flange includes a necked-down portion adjacent the forward section of the compressor casing, the necked-down portion positioned axially between an inlet of the bleed slot and an outlet of the bleed slot, and wherein the outboard wall extends axially aft and radially outboard from the inlet of the bleed slot to define a wall of an annular extended diffuser, wherein the wall of the annular extended diffuser terminates in a free end that is located aft of the annular supplemental flange.
