Abstract
A turbine blade with a plurality of rows of micro sized near wall cooling channels formed within an outer side of the airfoil wall to produce near wall cooling of the hot surface of the airfoil. The near wall cooling channels extend around the entire airfoil surface from the trailing edge to the leading edge regions and are formed using a metal printing process. Each row of near wall cooling channels discharges into a trench that opens onto the blade tip to provide a seal against hot gas leakage across the blade tips.
