COOLING STRUCTURE FOR STATIONARY BLADE

摘要

Embodiments of the present disclosure provide a cooling structure for a stationary blade (200), including: an endwall (204) coupled to a radial end of an airfoil (150); a chamber (218) positioned within the endwall (204) and radially displaced from a radially outer end of the trailing edge of the airfoil (150), wherein the chamber (218)includes a pair of opposing chamber walls (222), one of the pair of opposing chamber walls (222) being positioned proximal to the pressure side surface of the airfoil (150) and the other of the pair of opposing chamber walls (222) being positioned proximal to the suction side surface (158) and the trailing edge of the airfoil (150), and wherein the cooling fluid in the chamber (218) is in thermal communication with least a portion of the endwall (204) positioned proximal to the pressure side surface (156) and the trailing edge of the airfoil (150); and a plurality of thermally conductive fixtures (260) positioned within the chamber (218).
