Abstract
A bleed case assembly is provided comprising an annular outer case and an inner case. The inner case comprises an annular shroud portion having a radially outer surface opposite a radially inner surface, and a generally planar flange extending radially outwardly from the radially outer surface. The flange includes a circumferential array of bleed openings formed therethrough. The flange is attached to the outer case so as to reduce the thermal response of the inner case.
Claims14
A bleed case assembly, comprising:
- an annular outer case having an aft wall;
- and
- an inner case comprising:
- an annular shroud portion having a radially facing outer surface opposite a radially facing inner surface and a forward wall extending between said inner surface and said outer surface;
- and
- a flange extending radially outwardly from said outer surface at a location aft of said forward wall, said flange including a circumferential array of bleed openings formed therethrough;
- wherein said flange is attached to said outer case so that an annular bleed slot is defined by said forward wall and said aft wall.

A case for a gas turbine engine, comprising:
- an annular shroud portion having a radially facing outer surface opposite a radially facing inner surface and a forward wall extending between said inner surface and said outer surface, said forward wall being disposed at an acute angle to said inner surface;
- and
- a flange extending radially outwardly from said outer surface at a location aft of said forward wall, said flange including:
- a circumferential array of bleed openings formed therethrough, radially adjacent said shroud portion, and
- a circumferential array of mounting holes formed therethrough, radially outward of said bleed openings.

A compressor assembly comprising:
- a rotor having a plurality of radially outwardly extending blades attached thereto;
- an annular outer case having an aft wall;
- and
- an annular inner case including:
- a first shroud portion surrounding said blades, said first shroud portion having a radially facing inner surface opposite a radially facing outer surface, said inner and outer surfaces being connected by a forward wall, and
- a flange which extends radially outward from said outer surface, said flange being connected to said outer case, aligned with the axial position of said blades, and having a plurality of bleed openings formed therethrough;
- wherein said inner case is disposed in spaced-apart relationship from said outer case so that an annular bleed slot is defined between said aft wall of said outer case and said forward wall of said first shroud portion of said inner case.
