Diffused holes for inter-segment purge and method

(canceled)

A ceramic matrix composite (CMC) blade outer air seal (BOAS) segment forming a portion of a substantially ring-shaped BOAS stage, the CMC BOAS segment comprising:

• a mateface extending axially between a leading edge and a trailing edge of the CMC BOAS segment and configured to form an inter-segment gap with an adjacent CMC BOAS segment;
• and
• a plurality of film cooling holes arranged in a plurality of rows and having constant diameter meters and diffused openings at the mateface configured to provide film cooling of the mateface.

A method of providing an inter-segment purge flow to a ceramic matrix composite (CMC) component segment forming a portion of a substantially ring-shaped gas turbine engine stage, the method comprising:

• disposing a first mateface of the CMC component segment next to a second mateface of an adjacent CMC component segment to form an inter-segment gap;
• and
• providing first film cooling of the first mateface via a first plurality of film cooling holes arranged in a plurality of rows and having constant diameter meters and diffused openings at the first mateface.
