Abstract
Described is an abradable component for a gas turbine engine that includes a base having an outboard side which receives a supply of cooling air in use and an inboard side with a plurality of walls thereon. The walls intersect one another to define an abradable network of open faced cells on a gas washed surface thereof, and at least one of the walls includes one or more through-holes for providing a flow of cooling air from the outboard side to the gas washed surface of the abradable network of open faced cells, when in use.

An abradable component for a gas turbine engine, comprising:
- a base having an outboard side which receives a supply of cooling air in use and an inboard side with a plurality of walls thereon, the walls intersecting one another to define an abradable network of open faced cells on a gas washed surface thereof,
- wherein at least one of the walls includes one or more through-holes for providing a flow of cooling air from the outboard side to the gas washed surface of the abradable network of open faced cells, when in use, and
- wherein one of the walls or an intersection at which two or more of the walls intersect one another includes a boss through which one of the one or more through-holes passes.
