1. A shroud for providing a flowpath boundary for hot combustion gas in a turbine of a gas turbine engine comprising:

  • a panel having a leading edge for first receiving said combustion gas, a trailing edge at an opposite end thereof from which said combustion gas flows downstream therefrom, an inner surface extending between said leading edge and said trailing edge defining said flowpath boundary, and an outer surface extending between said leading edge and said trailing edge and spaced from said panel inner surface;

    said panel further including a cooling passage extending from an intermediate location between said leading and trailing edges toward one of said leading and trailing edges;

    said cooling passage having an inlet disposed at said intermediate location for receiving cooling air from adjacent said panel outer surface, a plurality of spaced apart turbulators disposed adjacent to said panel inner surface for enhancing heat transfer, and an outlet disposed at said one edge for discharging said cooling air from said cooling passage and along said panel inner surface at least a portion of said passage between said inlet and said outlet being generally parallel to said panel inner surface.
