A spacer for a gas turbine engine comprising:
- a rotor ring defined along an axis of rotation;
- and
- a plurality of core gas path seals which extend from said rotor ring, each of said plurality of core gas path seals extend from said rotor ring at an interface, said interface defined along a spoke, and wherein said interface includes a heat treat transition.
A spacer for a gas turbine engine comprising:
- a rotor ring defined along an axis of rotation;
- and
- a plurality of core gas path seals which extend from said rotor ring, each of said plurality of core gas path seals extend from said rotor ring at an interface, said interface defined along a spoke, and wherein said interface includes a bond.
A spacer for a gas turbine engine comprising:
- a rotor ring defined along an axis of rotation and wherein said ring defines a first circumferential flange and a second circumferential flange, said second circumferential flange thicker than said first circumferential flange, and further comprising a ramped interface between said second circumferential flange and said first circumferential flange;
- and
- a plurality of core gas path seals which extend from said rotor ring, each of said plurality of core gas path seals extend from said rotor ring at an interface, said interface defined along a spoke.
A spool for a gas turbine engine comprising:
- a first rotor disk defined along an axis of rotation;
- a plurality of first blades which extend from said first rotor disk;
- a rotor ring defined along said axis of rotation, said rotor ring in contact with said first rotor disk;
- a plurality of core gas path seals which extend from said rotor ring, said plurality of core gas path seals adjacent said plurality of first blades, each of said plurality of core gas path seals extend from said rotor ring at an interface, said interface defined along a spoke;
- and
- a first circumferential wire seal between said plurality of core gas path seals and said plurality of first blades.
