Grid ceramic matrix composite structure for gas turbine shroud ring segment
Abstract: A ceramic matrix composite (CMC) component such as a ring seal segment ( 50, 50 A, 50 B, 50 C, 50 D) for a gas turbine engine ( 10 ), the component formed with a base plate ( 52 ) and a frame portion ( 54 ) that extends substantially normally from the base plate around its perimeter. A grid of intersecting CMC ribs ( 73 ) is formed on the base plate within the frame portion. The ribs have a height (H) that may be within 3 times the total thickness (B) of the base plate, including any rib base ( 39 ) bonded to the base plate, along at least most of the rib length. The grid of ribs may be assembled from an array of CMC cups ( 40 ) bonded to the base plate, to adjacent cups, and to the frame portion.
