A rotor blade (100) is provided. The rotor blade includes an airfoil (106) extending radially between a blade root and a blade tip, and a tip shroud (112) extending from the blade tip. The tip shroud includes a pair of opposite sides (118, 120), a circumferential width measured between the pair of opposite sides, a first section (126) of increased cross-sectional thickness relative to at least some adjacent portions of the tip shroud, the first cross-sectional thickness section is adjacent to a first side of the pair of opposite sides and defining a first interlock surface (122) that forms a portion of the first side, a second section (128) of increased cross-sectional thickness relative to at least some adjacent portions of the tip shroud, the second cross-sectional thickness section is adjacent to a second side of the pair of opposite sides and defining a second interlock surface (124) that forms a portion of the second side, and an intermediate portion (130) extending along the circumferential width between the first and second increased cross-sectional thickness sections, the intermediate portion includes a reduced cross-sectional thickness relative to the first and second increased cross-sectional thickness sections. |
