1. A turbine shroud comprising:
a body including a structural member thereon, and a forward end positioned opposite an aft end, wherein the body is configured for coupling to a turbomachine casing; and
a cooling circuit within the body and in fluid communication with a cooling chamber defined radially outward of the body, the cooling circuit including:
a plurality of inlet passages extending through the structural member of the body and spaced along a length thereof, and
an outlet passage fluidly coupled to the inlet passages and extending through an external surface of the body,
wherein the structural member includes a rib on a radially outward surface of the body, the rib extending between the forward end and the aft end, and the cooling circuit includes at least one first plenum extending within the rib of the body and in fluid communication with the plurality of inlet passages, wherein the plurality of inlet passages are shaped to direct a cooling air into the first plenum and toward an underside surface of the structural member.
