Abstract
A compressor rotor includes a first disk and a conical section connected to the first disk. The conical section includes at least one flow hole. A bore cavity is defined between the conical section and the first disk. The bore cavity is arranged in fluid communication with the at least one flow hole. An anti-vortex tube is disposed within the at least one flow hole of the conical section and includes at least one feature arranged in contact with a surface of the conical section to restrict movement of the anti-vortex tube out of engagement with the conical section.
Claims20
A compressor rotor comprising:
- a first disk;
- a conical section connected to the first disk, the conical section including at least one flow hole;
- a bore cavity defined between the conical section and the first disk;
- the bore cavity being arranged in fluid communication with the at least one flow hole;
- and
- an anti-vortex tube disposed within the at least one flow hole of the conical section, the anti-vortex tube including at least one feature arranged in contact with a surface of the conical section to restrict movement of the anti-vortex tube out of engagement with the conical section.
A gas turbine engine, comprising:
- a compressor section, a combustor section, and a turbine section arranged in fluid communication such that an annular flow path extends axially through the compressor section, the combustor section, and the turbine section;
- the compressor section including:
- a conical section including at least one flow hole;
- a bore cavity defined within the conical section, the bore cavity being arranged in fluid communication with the at least one flow hole;
- and
- an anti-vortex tube disposed within the at least one flow hole of the conical section, wherein a contour of the anti-vortex tube restricts movement of the anti-vortex tube relative to the conical section.
A method of installing an anti-vortex tube relative to a compressor rotor comprising:
- inserting an anti-vortex tube into a flow hole formed in the compressor rotor;
- and
- transforming an inlet end of the anti-vortex tube inserted within the flow hole from a first configuration to a second configuration to restrict movement of the anti-vortex tube relative to the compressor rotor.
