A shroud 22 includes a panel 28 having leading and trailing edges 28a,b and inner and outer surfaces 28c,d extending therebetween. A cooling passage 38 extends through the panel 28 from adjacent the leading edge 28a to an intermediate location and is generally parallel to the inner and outer surfaces 28c,d. The cooling passage 38 has an inlet 40 for receiving cooling air from adjacent the panel outer surface 28d, a plurality of spaced apart turbulators 42 disposed adjacent to the panel inner surface 28c, and an outlet 44 disposed at the leading edge 28a for discharging the cooling air from the passage 38.
