Abstract
A turbine blade includes a tip cap disposed over an outer wall of a blade airfoil. A trench is defined on a radially outer side of the tip cap facing a hot gas path fluid. The trench is formed by a trench floor flanked on laterally opposite sides by first and second trench side faces such that the trench floor is located radially inwardly in relation to a radially outer surface of the tip cap. The trench extends from a trench inlet located at or proximal to an airfoil leading edge to a trench outlet located at or proximal to an airfoil trailing edge. The trench is configured to entrain a tip leakage flow from the trench inlet to the trench outlet.
