Abstract
A turbine blade for a turbine engine having a cooling system in the turbine blade formed from at least one elongated tip cooling chamber for passing cooling fluids in close proximity to an outer surface of the tip section of a turbine blade. The cooling system may include one or more elongated tip cooling chambers positioned in the tip section of a turbine blade for receiving cooling fluids through metering slots for regulating the flow and for exhausting those fluids from the turbine blade through the pressure sidewall to be used in external film cooling applications. The elongated tip cooling chambers enable the outer wall forming the tip section to be cooled internally and externally with cooling fluids.
