Abstract
A blade includes an airfoil that extends from a root end to a tip end. The airfoil includes a cooling channel defined therein. The blade further includes a tip shroud extending from the tip end, and at least one fillet coupled between the tip end and the tip shroud. The at least one fillet includes an interior wall. The interior wall at least partially defines a cavity in downstream flow communication with the cooling channel.
