SEAL ARC SEGMENT WITH CMC-PLY CUTOUTS FOR COOLING CHANNELS, GAS TURBINE ENGINE AND METHOD OF FABRICATING A SEAL ARC SEGMENT
A seal arc segment (62) includes a wall (63) that defines radially inner and outer sides (62e, 62f), forward and aft ends (62a, 62b), and first and second circumferential sides (62c, 62d). The wall (63) includes a CMC ply lay-up of a radially inner-most CMC ply (68a) on the inner side (62e), a radially outer-most CMC ply (68b) on the radially outer side (62f), and radially intermediate CMC plies (68c) therebetween. At least one of the radially intermediate CMC plies (68c) has cutout voids (70) that define cooling channels in the wall (63). The cooling channels are bound on lateral channel sides (70a, 70b) by the at least one of the radially intermediate CMC plies (68c), bound on a radially inner channel side (70c) by a first adjacent one of the CMC plies, and bound on a radially outer channel side (70d) by a second, different adjacent one of the CMC plies. The radially outer-most CMC ply (68b) includes at least one inlet hole (65) connected to the cooling channels for providing cooling air.
