Grid ceramic matrix composite structure for gas turbine shroud ring segment
摘要:
A ceramic matrix composite (CMC) component such as a ring seal segment (50, 50A, 50B, 50C, 50D) 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.
