Abstract
Systems provide enhanced cooling of tip regions of turbine blades. A cooling system includes a turbine blade with a root, a base, a tip, a leading edge, a trailing edge, an outer structure that includes a pressure side wall, a suction side wall and a tip cap at its tip. A core in the blade defines a leading channel that ejects cooling air through the leading edge. A primary tip flag channel ejects cooling air through the tip and the trailing edge. A secondary tip flag channel ejects cooling air through the trailing edge. The primary tip flag channel and the secondary tip flag channel promote cooling of the tip due to the locations in the tip area and their delivery of low temperature and high pressure cooling air thereto.
