Abstract
An air bleed system for a gas turbine engine includes an annular bleed case with a manifold therein. The annular bleed case has a forward section and an aft section and ligaments connecting the two sections. The forward section, the aft section and the ligaments define bleed ports. The manifold is disposed radially outward of the ligaments and communicates with the series of bleed ports.
Claims20
An air bleed system for a gas turbine engine, comprising:
- an annular bleed case having a forward section, an aft section, ligaments connecting the forward section to the aft section, and bleed ports defined by the forward section, the aft section and the ligaments defining bleed ports;
- and
- a manifold disposed radially outward of the ligaments and communicating with the series of the bleed ports.
An air bleed system for a gas turbine engine, comprising:
- a compressor section;
- and
- a bleed case having an inlet and an outlet, the inlet communicating with the compressor section;
- the bleed case comprising:
- a forward section;
- an aft section;
- ligaments connecting the forward and aft sections;
- bleed ports are defined by the forward section, the aft section, and the ligaments, and wherein the bleed ports communicate with the inlet;
- and
- a manifold formed within the case adjacent the outlet and communicating with the bleed ports.
An air bleed system for a gas turbine engine, comprising:
- an annular bleed case having a forward section and an aft section and ligaments connecting the two sections, the forward section, the aft section and the ligaments defining a series of bleed ports circumferentially disposed around the circumference of the bleed case;
- and
- a manifold disposed radially outward of the ligaments and extending circumferentially to communicate with the series of bleed ports.
