ABSTRACT:
A turbine blade has a shroud, a blade portion and a T-section root portion configured to lock into a T-section channel in a turbine rotor adjacent like blades in a ring. The blade portion is pre-twisted so that mutual alignment of the edges of the root and the shroud portion along the axis of the turbine in the final assembled condition provides a torsional bias which maintains the shroud in frictional contact with its neighbours to resist relative radial movement. The root portions have generally flat-sided surfaces occupying opposed substantially parallel radial planes of the T-section, but have circumferential abutments in the form of lands projecting from each side of the root portion at the same radius. When the circumferential abutments are radially aligned in the final assembled position, angular separation between adjacent blades is greater, by an amount related to the combined thickness of the abutments, than when the abutments are radially staggered.
