Abstract
A turbine vane usable in a turbine engine and having at least one cooling system. The cooling system including an aft cooling circuit formed from at least one serpentine cooling path. The serpentine cooling path having at least one rib may include bypass orifices for allowing air to pass through the rib to shorten the distance of the serpentine cooling path through which at least some of the air passes. The bypass orifices allow a greater quantity of air to pass through the vane and be expelled into a disc to which the vane is movably coupled as compared to a similar shaped and sized serpentine cooling path not having the bypass orifices.
