A gas turbine engine includes a rotor that that has a seal surface, a shaft that has an annular seal channel that opens to the seal surface, and a seal disposed in the annular seal channel for sealing against the seal surface. The seal is made of a composite having carbon fibers disposed in a carbon matrix.

Gas turbine engine with carbon/carbon composite piston seal

A gas turbine engine is provided and includes a first rotor element defining a groove, a second rotor element disposed to rotate about the first rotor element and a piston seal ring (PSR) disposed in the groove to form a seal between the first rotor element and the second rotor element. The second rotor element is formed to define bypass flow channels about the PSR that extend between opposite axial sides of the PSR.

Seal flow bypass

A method of plugging a honeycomb body is disclosed herein, the method comprising: contacting a first end of the honeycomb body comprising a plurality of channels with a light curable sealing mixture such that an infiltrate of the light curable sealing mixture flows into the plurality of channels proximate the first end; emitting a light toward a first portion of the infiltrate within the plurality channels of the filter; and curing the first portion of the infiltrate within the channels with the light to form a plurality of seals.
