Abstract
A turbomachine includes a rotor assembly including a wheel member. The wheel member includes a first portion that extends to a second portion through an intermediate portion. The intermediate portion partially defines a first wheel space and a second wheel space. The wheel member further includes a rotor inertia belt member arranged at the second portion. The rotor inertia belt member includes an extraction air cavity. The extraction air cavity includes an inlet, a first plurality of extraction air passages each including an inlet section and an outlet section, the outlet section leading into the first wheel space, and a second plurality of extraction air passages each including an inlet portion and an outlet portion, the outlet portion leading into the second wheel space.
Claims16
A turbomachine comprising:
- a rotor assembly including at least one wheel member having:
- a first portion, that extends to a second portion through an intermediate portion, the intermediate portion partially defining a first wheel space and a second wheel space;
- and
- a rotor inertia belt member arranged at the intermediate portion of the at least one wheel member, the rotor inertia belt member including an extraction air cavity having an inlet, a first plurality of extraction air passages each including an inlet section and an outlet section, the inlet section being fluidly connected to the inlet and the outlet section leading into the first wheel space, and a second plurality of extraction air passages each including an inlet portion and an outlet portion, the inlet portion being fluidly connected to the inlet and the outlet portion leading into the second wheel space.
A method of extracting air from a turbomachine, the method comprising:
- guiding an air flow into an extraction air cavity formed in a rotor inertia belt member of a wheel member;
- passing a first portion of the air flow through a first plurality of extraction air passages formed in the rotor inertial belt member, the first plurality of extraction air passages extending between the extraction air cavity and a first wheel space;
- and
- passing a second portion of the air flow through a second plurality of extraction air passages formed in the rotor inertial belt member, the second plurality of extraction air passages extending between the extraction air cavity and a second wheel space.
