Abstract
A rotor blade for a gas turbine configured for use within a row of samely configured rotor blades. The rotor blade may include an airfoil defined between pressure and suction faces and a midspan shroud. The midspan shroud may include pressure and suction wings. The pressure wing and suction wing of the midspan shroud may be configured so to cooperatively form an interface between neighboring ones of the rotor blades within the row of samely configured rotor blades. The interface may include: a pressure wing contact face disposed on the pressure wing that opposes across a gap a suction wing contact face disposed on the suction wing; and a predetermined offset between the pressure wing contact face and suction wing contact face. The predetermined offset may be configured for desirably aligning the contact faces when an expected operating condition closes of the gap.
