A turbine rotor blade (10) includes an airfoil (12) having pressure and suction sidewalls (26,28) extending longitudinally in span from root (30) to tip (32). The sidewalls (26,28) are spaced apart between leading and trailing edges (34,36) and joined together by longitudinal partitions (38) defining flow channels (1-8) therein. Rows of first and second slant turbulators (40-46) extend from one of the sidewalls in one of the channels and are offset longitudinally. The first and second turbulators (40-46) overlap chordally to eliminate an axial gap therebetween while maintaining a radial gap for tripping cooling air channeled along the span of the channel.
