EROSION-SHIELDED TURBINE BLADES AND METHODS OF MANUFACTURING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17973085 titled 'EROSION-SHIELDED TURBINE BLADES AND METHODS OF MANUFACTURING THE SAME

Simplified Explanation

The patent application describes a method of forming an erosion shield for a turbine blade by depositing layers of filler material and erosion-resistant material, machining the filler material, and attaching the shield to the leading edge of the blade.

• The method involves depositing a layer of filler material with an upper surface.
• A layer of erosion-resistant material is then deposited on top of the filler material.
• An interface is defined between the filler material and erosion-resistant material.
• The filler material is machined to create the erosion shield.
• The inner surface of the shield is shaped for attachment to the turbine blade.

Original Abstract Submitted

A method of forming an erosion shield for a turbine blade includes depositing a layer of filler material defining an upper surface. The method also includes depositing a layer of erosion-resistant material across the upper surface of the layer of filler material. An interface is defined between the layer of filler material and the layer of erosion-resistant material and has a shape of the upper surface. The method also includes machining the layer of filler material to produce the erosion shield. The erosion shield has the layer of erosion-resistant material, the machined layer of filler material, and the interface defined therebetween. An inner surface of the erosion shield is defined by the machined layer of filler material that is sized and shaped for attaching to a leading edge of the turbine blade. Each of the interface and the inner surface extend a length of the erosion shield.
