Abstract
A rotor assembly includes a first rotor, a second rotor mounted on the first rotor and co-rotatable there with, and a thermal shield interlocked with the second rotor for co-rotation there with.
Claims13
A rotor assembly comprising:
- a first rotor;
- a second rotor mounted on the first rotor and co-rotatable there with;
- and
- a thermal shield interlocked with the second rotor for co-rotation there with, wherein the first rotor has a first outer diameter and the second rotor has a second outer diameter that is smaller than the first outer diameter, and the second rotor includes at least one radially-extending tab and the thermal shield includes at least one radially-extending tab circumferentially interlocked with the at least one radially-extending tab of the second rotor.
