Abstract
A reinforced rotor disk assembly includes a rotor disk having a rim, hub, and web therebetween. The web includes at least one annular extension spaced radially inwardly of the rim. A plurality of rotor blades extend outwardly from the rim. And, a reinforcing ring is disposed radially around the extension for restraining radial outward growth thereof to react centrifugal load in the disk. The reinforcing ring preferably includes a plurality of circumferentially extending structural fibers in a corresponding matrix for carrying hoop loads therein.
Claims8
A gas turbine engine rotor assembly comprising:
- a rotor disk including a radially outer rim, a radially inner hub, and a web extending therebetween, said web including at least one coaxial annular extension spaced radially inwardly of said rim to define a cavity therebetween;
- a plurality of circumferentially spaced apart rotor blades extending radially outwardly from said rim;
- a reinforcing ring disposed in said cavity radially around said extension for restraining radial outward growth of said extension to react centrifugal load in said disk upon rotation thereof, and wherein said ring includes a plurality of circumferentially extending structural fibers in a matrix for carrying hoop loads therein;
- and
- means for axially retaining said ring on said extension including a split ring retainer disposed in a complementary slot in said rim and axially abutting said reinforcing ring.
A gas turbine engine rotor assembly comprising:
- a first rotor disk including a radially outer rim, a radially inner hub, and a web extending therebetween, said web including at least one coaxial annular extension spaced radially inwardly of said rim to define a cavity therebetween;
- a plurality of circumferentially spaced apart rotor blades extending radially outwardly from said rim;
- a reinforcing ring disposed in said cavity radially around said extension for restraining radial outward growth of said extension to react centrifugal load in said disk upon rotation thereof, and wherein said ring includes a plurality of circumferentially extending structural fibers in a matrix for carrying hoop loads therein:
- and
- means for axially retaining said ring on said extension including an adjacent second rotor disk fixedly joined to said first disk.
