PROBLEM TO BE SOLVED: To provide a turbine engine component relating to heat transfer through a component wall. SOLUTION: A turbine engine component such as a shroud, an airfoil portion or the like includes a wall (10) having a first wall surface (12) which receives a first temperature from flow in the engine. The wall (10) contains a second wall surface (14) substantially opposing to the first wall surface (12). The second wall surface (14) is exposed to cooling fluid, for example, cooling air. The second wall surface (14) includes a plurality of adjacent ribs (16) projected from the second wall surface (14) to promote heat transfer from the second wall surface (14). The rib (16) includes a plurality of elongated rib portions (22). The adjacent rib portions (22) are provided with a gap (20) interposed therebetween. The gap (20) has a length (24) ranging from about 0.002 inches to 0.05 inches (0.0508 mm to 1.270 mm). COPYRIGHT: (C)2003,JPO
