A blade outer air seal (BOAS) for a gas turbine engine, comprising:
- a seal body having a radially inner face and a radially outer face that axially extend between a leading edge portion and a trailing edge portion;
- and
- a multitude of cooling fins disposed around the radially outer face of the seal body, at least one of the multitude of cooling fins having at least one aperture.
A gas turbine engine, comprising:
- an engine casing;
- a seal body having a radially inner face and a radially outer face that axially extend between a leading edge portion and a trailing edge portion, the radially outer face adjacent to the engine casing;
- a seal secured to the radially inner face of the seal body;
- and
- a multitude of cooling fins disposed around the radially outer face between the leading edge portion and the trailing edge portion, at least one of the a multitude of cooling fins having at least one aperture.
A method of controlling a specific rate of thermal expansion that will match a corresponding blade design by using a cooling fin arrangement attached to a blade outer air seal (BOAS) for a gas turbine engine, comprising:
- controlling an area of at least one aperture in each of a multitude of cooling fins disposed around a radially outer face of the seal body.
