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, 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.
Abstract(Chinese):

一种陶瓷基复合材料（CMC）组件，例如用于燃气涡轮发动机（10）的环形密封段（50,50A，50B，50C，50D），所述部件形成有基板（52）和框架部分 ），其基本上正常地从基板围绕其周边延伸。 在框架部分中的基板上形成有相交的CMC肋（73）的格栅。 这些肋的高度（H）可以在底板的总厚度（B）的3倍内，包括至少大部分肋长度结合到底板上的任何肋基座（39）。 肋的格栅可以从结合到基板的CMC杯（40）阵列到相邻的杯和框架部分组装。
