  • COOLED TURBINE RING SEGMENTS WITH INTERMEDIATE PRESSURE PLENUMS
    Publication number: 20140286751
    Abstract: A ring segment for a gas turbine engine includes a panel and a cooling system. The cooling system is provided within the panel and includes an elongated intermediate plenum extending parallel to leading and trailing edges of the ring segment, and is located radially between an inner side of the panel and a hook structure extending from an outer side of the panel. A plurality of cooling fluid feed passages supply cooling fluid to the intermediate plenum, and a plurality of convective cooling passages extend through the panel from the intermediate plenum to one of the leading and trailing edges for cooling the inner side of the panel. The intermediate plenum is located in axial alignment with and defines an area of reduced thermal mass receiving impingement cooling adjacent to the hook structure.

    Publication number: 20140034215
    Abstract: An apparatus and method for improving friction spot welding process is described herein. According to the method of the present invention, two different metal sheets of similar or dissimilar material can be joined together with the help of a filler material that is filled in a cavity formed at the top of the upper metal sheet. Additionally, either a reinforcement material or an alloy element or combination of both is added in the cavity. The material is plasticized as the filler material is rotated and pushed in the cavity under the application of force. The weld is completed by filling the entire filler material at the weld interface. The addition of reinforcement material or an alloy element enables in customization of interface material properties enhancing the joint strength.
