Abstract
An integrally bladed rotor includes a monolithic rotor body that has a bore portion, a rim, and a web that joins the bore portion and the rim. A plurality of blades extends outwardly from the rim. An arm that extends axially off of the rim, and there is a pocket on a radially inner side of the arm.
Claims19
An integrally bladed rotor comprising:
- a monolithic rotor body that includes a bore portion, a rim, a web joining the bore portion and the rim, a plurality of blades that extend outwardly from the rim, an arm that extends axially off of the rim, the arm having a first portion and a second frustoconical portion, and a pocket on a radially inner side of the arm, wherein a radially most outward surface of the rim is configured to bound a fluid flowpath at one or more of the blades, and wherein a first end of the second frustoconical portion is directly connected to the first portion and a second end of the second frustoconical portion is directly connected to a forward edge of the most radially outward surface.
A gas turbine engine comprising:
- a compressor section;
- a combustor section in communication with the compressor section;
- and
- a turbine section in communication with the combustor section,
- wherein the compressor section has an integrally bladed rotor that includes:
- a monolithic rotor body that includes a bore portion, a rim, a web joining the bore portion and the rim, a plurality of blades that extend outwardly from the rim, an arm that extends axially off of the rim, the arm having a first portion and a second frustoconical portion, and a pocket on a radially inner side of the arm, wherein a radially most outward surface of the rim bounds a flowpath of fluid through the compressor section at one or more of the blades, and wherein a first end of the second frustoconical portion is directly connected to the first portion and a second end of the second frustoconical portion is directly connected to a forward edge of the most radially outward surface.
