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 system includes a cover segment configured to mount in first and second grooves circumferentially along a blade mounting region of a turbine rotor. The cover segment includes a cover body and at least one fastener. The cover body includes first and second lips extending along first and second circumferential portions of the cover body at an offset from one another. The first lip is configured to mount circumferentially along the first groove and the second lip is configured to mount circumferentially along the second groove. The at least one fastener is configured to retain the cover body to the turbine rotor or at least one blade mounted in the blade mounting region.
