Abstract
The present invention relates to an axial flow rotary machine and to a maintainable compressor bleed system therefore. The axial flow rotary machine comprises a primary flow path for a working medium, a secondary flow path for the working medium, a bleed system for allowing a bleed portion of the working medium flowing in the primary flow path to be delivered to the secondary flow path, a support structure for the bleed system located radially inboard of the bleed system, and the panels for gaining access to the bleed system. The panels are located radially outboard of the bleed system. The panels form the inner flow wall for the primary flow path.
Claims18
An axial flow rotary machine comprising:
- a primary flow path for a working medium;
- a secondary flow path for said working medium;
- a bleed system for allowing a bleed portion of the working medium flowing in said primary flow path to be delivered to said secondary flow path;
- a support structure for said bleed system located radially inboard of said bleed system;
- and
- a panel for gaining access to said bleed system, said panel being located radially outboard of said bleed system.
A bleed system for use in a gas turbine engine for opening and closing a bleed passageway which allows a working medium to flow from a primary flow path to a secondary flow path, said bleed system comprising:
- a bleed valve movable between a first position where said bleed passageway is closed and a second position where said bleed passageway is open;
- actuation means for moving said bleed valve between said first position and said second position;
- said actuation means being supported by a support structure;
- said valve and said actuation means being located radially outboard of said support structure;
- and
- a removable access panel secured to said support structure.
