Abstract

A vane adapted for use in a gas turbine engine includes a forward following serpentine cooling path having a plurality of divider walls to direct cooling airflow. The serpentine cooling path optionally includes one or more bifurcating walls in the cooling path to split the airflow. The serpentine cooling path is in communication with an aft inlet in the vane and air passing through the serpentine cooling path exits a forward outlet in the vane into a forward rotor/stator cavity.
