Abstract
A turbine engine has a first disk and a second disk, each extending radially from an inner aperture to an outer periphery. A coupling, transmits a torque and a longitudinal compressive force between the first and second disks. The coupling has first means for transmitting a majority of the torque and second means, radially outboard of the first means, for transmitting a majority of the force.
Claims23
A turbine engine comprising:
- a first disk and a second disk, each extending radially from an inner aperture to an outer periphery;
- and
- a coupling, transmitting a torque and a longitudinal compressive force between the first and second disks and comprising:
- first means for transmitting a majority of the torque;
- and
- second means, radially outboard of the first means for transmitting a majority of the force.
3 more elements
A thermally-controlled, center-tied, rotor comprising:
- a central shaft;
- a plurality of blade disks, the disks each having a central aperture surrounding the shaft, and the disks defining annular cavities between adjacent pairs of the disks;
- one or more circumferentially-distributed anti-vortex tubes extending within at least a first of said cavities between first and second of said disks;
- and
- a radially compliant seal between the shaft and at least one of said disks.
2 more elements
A turbine engine rotor comprising:
- a plurality of disks, each disk extending radially from an inner aperture to an outer periphery;
- a plurality of stages of blades, each stage borne by an associated one of said disks;
- a plurality of spacers, each spacer between an adjacent pair of said disks;
- and
- a central shaft carrying the plurality of disks and the plurality of spacers to rotate about an axis with the plurality of disks and the plurality of spacers, wherein:
- a first of the spacers transmits a longitudinal compressive force between a first and a second of the disks;
- and
- interfitting first and second portions of said first and second disks radially inboard of said first spacer transmit longitudinal torque between the first and second disks.
5 more elements
A system for coupling first and second turbomachine disks comprising:
- first interfitting portions of the first and second disks;
- and
- a spacer, spaced radially outboard of the first interfitting portions, the spacer having a longitudinally outwardly concave portion.
