Abstract
This disclosure provides components and methods for blade extensions with internal features. An airfoil extends from a root connector and includes an airfoil body defining at least one air channel enclosed within the airfoil body. The air channel extends to a build surface. An additive extension extends from the build surface of the airfoil body. The additive extension includes an additive structure extending the air channel from the build surface to an external surface of the additive extension.
