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.

Abstract: The present disclosure is directed to a retention assembly for a stationary gas turbine component. A first stationary gas turbine wall defines a first wall cavity and a second stationary gas turbine wall constructed from a ceramic matrix composite defines a second wall cavity. A pin shaft constructed from a first material includes a first shaft end and a second shaft end. A pin head constructed from the ceramic matrix composite includes a first pin head end and a second pin head end. The pin head defines a pin head cavity extending inward from the first pin head end. The first shaft end is positioned in the first wall cavity, and the second shaft end is positioned in the pin head cavity. The second pin head end is positioned in the second wall cavity. The first material is different from the ceramic matrix composite.

Abstract: In one aspect the present subject matter is directed to a system for thermally isolating a turbine shroud of a turbine shroud assembly. The system includes a shroud support having an inner surface and a turbine shroud that is connected to the shroud support. The turbine shroud includes a hot side surface that is radially spaced from a back side surface. At least a portion of the back side surface is oriented towards the inner surface of the shroud support. The system further includes a coating that is disposed along the back side surface of the turbine shroud. The coating regulates heat transfer from the turbine shroud to the shroud support or other hardware that may surround or be adjacent to the turbine shroud.
