Claims8
A turbine blade comprising:
- a root section for engaging with a rotor;
- a platform having a bottom surface connected to the root section, a top surface distal to the root section, and an edge circumscribing the platform and comprising an edge surface orthogonal to the bottom surface and the top surface;
- and
- an airfoil extending from the top surface of the platform, the airfoil having a suction side and a pressure side;
- wherein a portion of the edge surface of the platform proximate to the suction side comprises a plurality of serrated teeth that are arranged to form a plurality of ridges, each ridge interspaced with a valley and extending perpendicularly to the top surface.
