Abstract
A system includes a turbomachine blade segment including an airfoil with an exterior surface, and a platform coupled to the airfoil having a first side and a second side. The system also includes a concave fillet transition extending between the airfoil and the platform. The concave fillet transition includes one or more interface ply segments extending across the exterior surface of the airfoil and the first or the second side of the platform to form a continuous surface between the airfoil and the platform.
Claims20
A system, comprising:
- a turbomachine blade segment, comprising:
- an airfoil comprising an exterior surface;
- a platform coupled to the airfoil, the platform comprising a first side and a second side;
- and
- a concave fillet transition extending between the airfoil and the platform, wherein the concave fillet transition comprises one or more interface ply segments extending across the exterior surface of the airfoil and the first or the second side of the platform to form a continuous surface between the airfoil and the platform.
