Title:
タービン構成要素ならびにタービン構成要素を作製および冷却する方法
Document Type and Number:
Japanese Patent JP7094664
Kind Code:
B2
Abstract:
A turbine component (10) includes a root (11) and an airfoil (12) extending from the root (11) to a tip (14) opposite the root (11). The airfoil (12) forms a leading edge (15) and a trailing edge portion (42) extending to a trailing edge (16). Radial cooling channels in the trailing edge portion (42) of the airfoil (12) permit radial flow of a cooling fluid through the trailing edge portion (42). Each radial cooling channel has a first end (50) at a lower surface (52) at a root (11) edge of the trailing edge portion (42) or at an upper surface (56) at a tip (14) edge of the trailing edge portion (42) and a second end (54) opposite the first end (50) at the lower surface (52) or the upper surface (56). A method of making a turbine component (10) and a method of cooling a turbine component (10) are also disclosed.
