Abstract
The present invention provides an airfoil body having a first wall including a plurality of ribs. An outer wall formed of a high temperature foil is attached to the ribs so as to form a plurality of channels. The first wall is protected from hot flowpath gases by the outer wall and by cooling air flowing through the channels.
Claims12
An airfoil comprising:
- an airfoil body having a root, a tip, a leading edge, and a trailing edge;
- a first wall extending from said leading edge to said trailing edge;
- a second wall extending from said leading edge to said trailing edge, said second wall having at least one rib extending therefrom;
- and
- an outer wall disposed in spaced apart relationship with second wall and attached to said rib, said outer wall comprising a high temperature foil.

An airfoil comprising:
- an airfoil body having a root, a tip, a leading edge, a trailing edge, a pressure side wall and a suction side wall;
- a suction side tip wall disposed at said tip and extending from said leading edge to said trailing edge;
- a pressure side tip wall disposed at said tip extending from said leading edge to said trailing edge, said pressure side tip wall being offset from said pressure side wall so as to define a tip shelf and having at least one rib extending therefrom;
- and
- an outer tip wall disposed on said pressure side of said tip in spaced apart relationship with said pressure side tip wall and attached to said rib, said outer tip wall comprising a high temperature foil.
