ABSTRACT:
A turbine blade for a turbine engine having a cooling system in at least an outer wall. The cooling system in at least the outer wall formed from at least a first plurality of parallel cavities intersected by a second plurality of parallel cavities positioned in a nonparallel position relative to the first plurality of parallel cavities. In at least one embodiment, the second plurality of parallel cavities may include an alternating configuration of cavities, such that a first cavity may be positioned proximate to an inner surface of the outer wall and a second cavity adjacent to the first cavity is positioned proximate to the outer surface of the outer wall. The first cavity may also be offset from the second cavity to form a spiral gas flow path. The cooling system in the outer wall of the turbine blade may form a spiral flow path.
