Abstract
In one aspect, the present subject matter is directed to a gas turbine sealing assembly that includes a first static gas turbine wall and a second static gas turbine wall. A seal is disposed between the first static gas turbine wall and the second static gas turbine wall. The seal includes a first seal layer defining a first seal layer aperture extending therethrough. A second seal layer defines an elongated slot extending therethrough. The elongated slot includes a first end and a second end. A third seal layer defines a third seal layer aperture extending therethrough. The second seal layer is positioned between the first seal layer and the third seal layer such that the first seal layer aperture is in fluid communication with the first end and the third seal layer aperture is in fluid communication with the second end.
