Ceramic matrix composite turbine engine components with unitary stiffening frame
First Claim
1. A turbine engine component comprising:
- a ceramic matrix composite body having a base portion and frame portion, the base portion and the frame portion being unitary, the frame portion including at least three unitary side walls that enclose a space, wherein each side wall transitions at opposite ends into one of the other side walls, each side wall extending substantially radially outward from the base portion, and wherein each side wall transitions into the base portion such that the frame portion is closed on one side wherein the transition between two side walls occurs in a side wall transition region, wherein the ceramic matrix composite includes a ceramic matrix and a plurality of fibers therein, wherein at least some of the fibers span continuously across the side wall transition region and extend into a portion of each of the two side walls;
the turbine engine component further including a combustor liner, wherein the body is operative connected to the combustor liner, whereby the turbine engine component is a heat shield.

Abstract
Aspects of the invention are directed to a ring seal segment having a base portion and a frame portion. The base portion and the frame portion are a unitary structure. The frame portion is made of four unitary side walls: a forward wall, an aft wall and a pair of transverse side walls. The side walls can be arranged in a rectangular configuration. At least a part of the base portion can be coated with a thermal insulating material. A ring seal segment according to aspects of the invention is well suited to withstand the expected operational loads in the turbine section. The transverse side walls can provide bending strength to the base and can strengthen the forward and aft side walls. Transition regions between the side walls and the base portion are strengthened by three perpendicular planes that cooperate to provide structural strength to the ring seal segment.
