SEALS FOR A GAS TURBINE ENGINE

摘要

A sealing assembly may include a support, an engine component, and a seal. The engine component may be mounted relative to the support to define a gap between the engine component and the support. The seal may be arranged between the support and the engine component to block gasses from passing through the gap. The seal may be adapted to compress and expand to fill the gap during expansion and contraction of the adjacent components that occurs during operation of a gas turbine engine including the sealing assembly.

1. A sealing assembly comprising
a support having a support-seal surface, an engine component having a component-seal surface, the engine component mounted so that the component-seal surface is arranged in spaced-apart confronting relation with the support-seal surface to define a gap between the support and the engine component that grows and shrinks based on the temperature of the support and the engine component, and a seal adapted to block gasses from passing through the gap between the support and the engine component, the seal including a mount ring coupled to the support and spaced apart from the engine component, a ceramic tadpole gasket having a compressible head held in contact with the engine component by the mount ring and a flat body extending from the compressible head into a retention channel formed by the mount ring, and a retainer ring arranged to extend into the retention channel of the mount ring to trap the flat body of the tadpole gasket in the retention channel formed by the mount ring so that the tadpole gasket is coupled to the mount ring.
