Abstract: A cooling assembly comprises a coolant source chamber inside an airfoil that directs coolant inside the airfoil that extends between a hub end and a tip end that includes a tip body and tip rail along a radial length. A first body cooling chamber and a second body cooling chamber are disposed inside the tip body. The second body cooling chamber is positioned between the tip end and the first body cooling chamber. At least one of the first or second body cooling chambers are fluidly coupled with the coolant source chamber. The coolant source chamber directs the coolant into the first or second body cooling chambers. A rail cooling chamber disposed inside of the tip rail is fluidly coupled with the first or second body cooling chambers. The first or second body cooling chambers directs coolant out of the body cooling chambers and into the rail cooling chamber.
