초록

Embodiments of the invention relate to a vane assembly formed by a forward airfoil segment and an aft airfoil segment. The aft segment is made of metal and can define the trailing edge of the vane assembly. The forward segment can be made of ceramic, CMC or metal. The forward and aft segments cannot be directly joined to each other because of differences in their rates of thermal expansion and contraction. The forward and aft segments can be positioned substantially proximate to each other so as to form a gap therebetween. In one embodiment, the gap can ...

What is claimed is: 1. An airfoil assembly comprising: a forward airfoil segment defining the leading edge of the airfoil assembly at one end and providing an interface surface at an opposite end; an aft airfoil segment defining the trailing edge of the airfoil assembly at one end and providing an interface surface at the opposite end, the aft airfoil segment being made of metal, wherein the interface surfaces of the airfoil segments are positioned substantially proximate to each other so as to form a gap therebetween; and a sealing device positioned in...
