Abstract

The present disclosure is directed to a retention assembly for a gas turbine component including a first and a second gas turbine wall respectively defining a first and a second surface. A retainer, positioned between the first and the second surfaces, includes a flange, which contacts the first surface. A plurality of fingers extends outwardly from the flange. A first finger portion extends away from the first turbine wall toward the second wall. A second finger portion connected to the first finger portion extends substantially parallel to the flange. The second finger portion of a first finger of the plurality of fingers is positioned in a first slot defined in the second surface. The second finger portion of a second finger of the plurality of fingers adjacent to the first finger is positioned on the second surface adjacent to the first slot.
