Abstract
A gas turbine engine is provided. The gas turbine engine includes a stage of airfoil segments having a first ceramic matrix composite (CMC) airfoil segment, the first CMC airfoil segment includes: an end band having a radial surface defining a cold side surface area, A; and an airfoil coupled to or formed with the end band, the airfoil and the end band defining a joint therebetween, the joint including one or more radial interfaces defining a total radial interface surface area, A, and one or more axial interfaces defining a total axial interface surface area, A. The first CMC airfoil segment defines a first ratio of the cold side surface area, A, to the total axial interface surface area, A, and a second ratio of the total axial interface surface area, Ato the total radial interface surface area, A.
