Patent abstract
A turbine blade for a turbine engine having an internal cooling system formed from a plurality of cooling chambers extending radially in the blade and configured to create vortices within the chambers. In at least one embodiment, the cooling system may be formed from leading edge cooling chambers, trailing edge cooling chambers, suction side mid-chord cooling chambers, and pressure side mid-chord cooling chambers that are configured to receive cooling fluids from supply channels in a root of the blade and to create vortices in the cooling chambers. The vortices of cooling fluids increase heat removal from the turbine blade. The cooling fluids may be exhausted from the turbine blade through film cooling orifices.
