Abstract
A sealing assembly (100) for at least partially sealing a gap (102) leading to a void (104) between first and second members (110, 120), the first and second members forming part of a gas-washed surface of a jet engine, wherein the sealing assembly comprises: a bridging portion (130) couplable to one of the first and second members and movable to engage the other of the first and second members so as to block off the void between the first and second members from the gas-washed surface.
Claims18
A sealing assembly for at least partially sealing a gap leading to a void between first and second members, the first and second members forming part of a gas-washed surface of a gas turbine, wherein the sealing assembly comprises:
- a bridging portion couplable to one of the first and second members and engaging the other of the first and second members so as to block off the void between the first and second members from the gas-washed surface,
- the bridging portion being adapted to have a movable configuration in which relative movement between at least a part of the bridging portion and the other of the first and second members is permitted and a permanent locked configuration in which relative movement between the at least a part of the bridging portion and the other of the first and second members is prevented, wherein in the locked configuration the bridging portion is locked by a cured filler that directly contacts the first and second members and the bridging portion.
A method of installing a sealing assembly for at least partially sealing a gap leading to a void between first and second members, the first and second members forming part of a gas-washed surface of a gas turbine, wherein the method comprises:
- providing a bridging portion coupled to one of the first and second members, the bridging portion being adapted to have a movable configuration in which relative movement between at least a part of the bridging portion and the other of the first and second members is permitted and a permanent locked configuration in which relative movement between the at least a part of the bridging portion and the other of the first and second members is prevented, applying a filler directly to the first and second members and the bridging portion and curing the filler to put the bridging portion into its locked configuration.
