  • Patent number: 10502063
    Abstract: A method of fabricating an airfoil includes forming a tip portion and imaging a second end of a body portion to obtain image data of one or more mortises formed therein. One or more tenons are formed on the first end of the tip portion using the image data of the second end of the body portion. The one or more tenons are manufactured using one of additive or subtractive manufacturing techniques. To complete assembly, the first end of the tip portion is positioned relative to the second end of the body portion such that each of the one or more tenons of the tip portion align with and are in sliding engagement with a respective one of the one or more mortises of the body portion. The body portion and the tip portion are coupled together such that the tip portion and the body portion form the airfoil. An airfoil formed by the method is also disclosed.
