ABSTRACT:
A turbulator used in a turbine blade of a gas turbine engine, the turbulators arranged along a wall of the cooling air passage in an inverted V-shape with a diffusion slot between adjacent turbulators. The turbulators have a frontal surface and a top surface that are both substantially flat, and in which both have an increasing width and height in the direction from the passage side wall toward the slot. The turbulators have an end face forming the slot that is substantially flat, and because of the slanted angle of the adjacent turbulators forms the divergent opening or slot between adjacent end faces.
