A mid-span shroud assembly comprises a suction side shroud body which defines a first spar. The first spar is formed to extend at least partially through a spar opening defined within the airfoil and includes a root portion, a tip portion, an upper face and a lower face. The upper and lower faces converge from the tip portion towards the root portion. The mid-span assembly further includes a pressure side shroud body. The pressure side shroud body defines a second spar which is formed to extend at least partially through the spar opening of the airfoil and includes a root portion, a tip portion, an upper face and a lower face. At least a portion of the upper face of the second spar is formed to be substantially parallel with the lower face of the first spar when both the first and second spars are inserted into the spar opening.

Turbine blade mid-span shroud

A mid-span shroud assembly for a turbine blade airfoil includes a pressure side shroud body which is associated with a pressure side wall of the airfoil and a suction side shroud body which is associated with a suction side wall of the airfoil. At least one of the pressure side shroud body and the suction side shroud body defines a coupling spar which is formed to extend at least partially through a bore hole defined within the airfoil of the turbine blade.
