CERAMIC MATRIX COMPOSITE AIRFOIL SEGMENT FOR GAS TURBINE ENGINE, CERAMIC MATRIX COMPOSITE STRUCTURE, AND METHOD FOR ASSEMBLING THE CERAMIC MATRIX COMPOSITE STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a geometry that provides continuity to fibers of a ceramic matrix composite material, and to maximize the strength per weight.SOLUTION: In each structure of the air foil segments 82, the box-shape ceramic-matrix-composite-fiber geometry 98 is used. Each of the ceramic matrix composite airfoil segments 82 defines a rectilinear pressure side bond line 100P and a rectilinear suction side bond line 100S on a circumferential segment of the ceramic matrix composite airfoil segments 82 to maintain aerodynamic performance and provide a strong bonding part. The rectilinear pressure side bond line 100P and the rectilinear suction side bond line 100S approximately align with a front edge 84L, a rear edge 84T, and respective platforms 90, 92.
