Abstract:
1. A turbomachine component, comprising: a turbine blade, which is rotatable about a rotor of a turbine for power generation operations; and a platform with which the turbine blade is to be assembled, the turbine blade being formed to define a main circuit having a circumferential appendage formed with radial tapering or curvature and extending circumferentially from the main circuit and the platform being formed to define: a platform circuit, and a substantially radially extendible pathway configured to be coupled to the appendage and to the platform circuit, wherein the appendage comprises a radially outward side, which is configured to be disposed proximate to the platform circuit, and which is configured with shallow tapering or curvature and a radially inward side, which is distant from the platform circuit, and which is configured with deep tapering or curvature, the deep tapering or curvature of the radially inward side being deeper than the shallow tapering or curvature of the radially outwardly side.
