Abstract
An improved joint for a turbine component including an outer wall member, an inner wall member disposed within the outer wall member, and at least one air channel formed therebetween. The improved joint preferably includes a plurality of elongated ribs extending from one of the outer and inner wall members, and a plurality of elongated grooves spaced from the other wall member and facing in registry with the plurality of ribs. The ribs are received in the grooves at joint interfaces to form a plurality of joints for interconnecting the inner and outer wall members. The formation of the elongated ribs and grooves in the improved joint provides a mechanical interlock at the joint interface to improve the strength of the joints, as well as to reduce undesirable heat transfer through the joints.
