Abstract
Official abstract text for this publication.
An airfoil assembly includes an airfoil body extending from a root to a tip defining a longitudinal axis therebetween. The airfoil body includes a leading edge between the root and the tip. A sheath is direct deposited on the airfoil body. The sheath includes at least one metallic material layer conforming to a surface of the airfoil body. In accordance with another aspect, a method for assembling an airfoil assembly includes directly depositing a plurality of material layers on an airfoil body to form a sheath. In accordance with some embodiments, the method includes partially curing the airfoil body.
First claim
Opening claim text (preview).
What is claimed is: 1. An airfoil assembly comprising: an airfoil body extending from a root to a tip defining a longitudinal axis therebetween, wherein the airfoil body includes a leading edge between the root and the tip; and a sheath direct deposited on the airfoil body, wherein the sheath includes at least one metallic material layer conforming to a surface of the airfoil body, wherein the sheath defines an internal pocket surrounded by the sheath, wherein at least a portion of the sheath is between the internal pocket and the leading edge of the airfoil body, wherein the at least one metallic material layer surrounds the internal pocket, and wherein the internal pocket includes a lattice structure that is surrounded by the at least one metallic material layer. 2. An airfoil as recited in claim 1 , wherein the sheath is direct deposited on the leading edge of the airfoil body. 3. An airfoil as recited in claim 1 , wherein the airfoil body includes a composite material. 4. An airfoil as recited in claim 1 , wherein the sheath includes a plurality of layers, wherein at least one of a composite or fiberglass structure is bonded in between layers of the sheath. 5. An airfoil as recited in claim 1 , wherein the sheath includes a plurality of layers. 6. An airfoil as recited in claim 5 , wherein the layers are alternating material layers. 7. An airfoil as recited in claim 5 , wherein an exterior layer includes a material of a higher erosion resistance than an interior layer. 8. An airfoil as recited in claim 5 , wherein a first layer in direct contact with the airfoil body includes a material having a lower deposition temperature than layers exterior to the first layer.
