Abstract
A turbine airfoil () includes a trailing edge coolant cavity () located in an airfoil interior () between a pressure sidewall () and a suction sidewall (). The trailing edge coolant cavity () is positioned adjacent to a trailing edge () of the turbine airfoil () and is in fluid communication with a plurality of coolant exit slots () positioned along the trailing edge (). At least one framing passage () is formed at a span-wise end of the trailing edge coolant cavity (). The airfoil () further includes framing features (A-B,A-B) located in the framing passage (). The framing features are configured as ribs (A-B,A-B) protruding from the pressure sidewall () and/or the suction sidewall (). The ribs (A-B,A-B) extend partially between the pressure sidewall () and the suction sidewall ().
