Abstract
A seal assembly for a gas turbine engine includes a seal carrier and a seal press fit within an inner diameter of the seal carrier. The seal includes an outer ring supporting a radially moveable shoe supported by at least one beam. The outer ring includes an inner radial surface having at least one tab extending radially inward toward the shoe for aiding removal of the seal from the carrier.

A seal assembly for a gas turbine engine comprising:
- a seal carrier;
- a seal press fit within an inner diameter of the seal carrier, the seal including an outer ring supporting a radially moveable shoe supported by at least one beam, the outer ring including an inner radial surface having at least one tab extending radially inward toward the shoe for aiding removal of the seal from the seal carrier, wherein the outer ring includes a first face and the seal carrier includes a stop wall portion extending radially inward, wherein the stop wall portion includes a plurality of circumferentially spaced carrier openings and the at least one tab comprises a plurality of tabs aligned circumferentially with and visible through the plurality of circumferentially spaced openings.
A seal assembly for a gas turbine engine comprising:
- a seal carrier;
- a seal press fit within an inner diameter of the seal carrier, the seal including an outer ring supporting a radially moveable shoe supported by at least one beam, the outer ring including an inner radial surface having at least one tab extending radially inward toward the shoe for aiding removal of the seal from the seal carrier, wherein the outer ring includes a first face and the seal carrier includes a stop wall portion extending radially inward, wherein the stop wall portion includes a plurality of circumferentially spaced carrier openings, wherein the at least one tab extends radially inward a distance less than a minimum distance between a radially outermost one of the at least one beam and the outer ring.
A gas turbine engine comprising:
- a core engine including a compressor section, a combustor and a turbine section;
- and
- a seal assembly disposed in at least one of the compressor section or the turbine section, wherein the seal assembly includes a seal carrier and a seal press fit within an inner diameter of the seal carrier;
- the seal including an outer ring supporting a moveable shoe supported by at least one beam, the outer ring including an inner radial surface having at least one tab extending radially inward toward the shoe for aiding removal of the seal from the seal carrier, wherein the at least one tab extends radially inward a distance less than a minimum distance between a radially outermost one of the at least one beam and the outer ring.
