Abstract: A method of providing cooling structure for a component including forming a first cavity in the component and forming a first passageway in the first cavity in fluid communication with a second cavity positioned inside the component, the second cavity in fluid communication with a cooling air source. The method includes forming a unitary insert including a first surface, a second surface, the insert having an inlet formed in the first surface and an outlet formed in the second surface. A second passageway is in fluid communication with the inlet and the outlet. The method includes positioning the insert in the first cavity into fluid communication with the first passageway, the first surface facing the first cavity; and rigidly attaching the insert in the first cavity.

Abstract: A process of producing a ceramic matrix composite component. The process includes positioning a plurality of ceramic matrix composite plies on top of one another and forming a cavity therein. At least a portion of the cavity includes a terminal diameter sufficiently small to permit infiltration of a densifying material. The plurality of ceramic matrix composite plies are densified to form a densified body. The densifying results in the portion of the cavity including the terminal diameter being filled with densifying material and the cavity is present in the densified body. A ceramic matrix composite having cavities therein is also disclosed.

Abstract: A turbine component is disclosed. The turbine component includes an outer shroud and an inner shroud having a first hook region extending over a first portion of the outer shroud and a second hook region extending over a second portion of the outer shroud. A first hook gap, a second hook gap, a first radial gap, and a second radial gap are arranged and disposed to permit the inner shroud to deflect from the outer shroud under thermal loading. Additionally or alternatively, the inner shroud includes ceramic matrix composite fibers having a thermal conductivity of less than 200 W/m·k and greater than 10 W/m·k.
