  • Publication number: 20080277090
    Abstract: An investment casting core combination includes a metallic casting core and a ceramic feedcore. A first region of the metallic casting core is embedded in the ceramic feedcore. The metallic casting core includes a plurality of body sections. The first region is along at least some of the body sections. The metallic casting core includes a plurality of springs spanning gaps between adjacent body sections and unitarily formed therewith.

  • Patent number: 7431559
    Abstract: A vane for use in a gas turbine engine has a leading edge facing an upstream combustor. The vane has hollow areas that receive an impingement tube for delivering impingement air. The impingement tube includes a radially outer portion and a radially inner portion. An end wall of the radially outer portion is angled relative to a rotational axis of the turbine such that air entering the impingement tube from a radially outer source has dirt directed away from the leading edge. Thus, dirt is less likely to clog leading edge air supply holes. In one embodiment, the inner and outer portions are formed as separate pieces, and in another embodiment, the inner and outer portions are formed as a single piece.

  • Publication number: 20080219854
    Abstract: An airfoil for a gas turbine engine component such as a turbine blade or a vane includes at least one microcircuit cooling channel having a plurality of sub-channels extending along a radial direction of the airfoil. The plurality of channels are axially spaced, and are fed by radially spaced inlets.

  • Publication number: 20080031739
    Abstract: An airfoil suitable for use in the turbine section of a jet engine. Said airfoil contains a core having a passage for conducting a coolant through said airfoil and discharging the coolant through a radially disposed slot at the trailing edge of the airfoil. A flow barrier is mounted adjacent to the discharge slot within the flow passage which contains openings for tailoring the coolant flow distribution profile in the trailing edge region based upon some identifiable airfoil property such as the airfoil's pressure and/or temperature profile, or a combination of the pressure and temperature profiles.

  • Publication number: 20070243065
    Abstract: A gas turbine engine component has a cooling scheme that utilizes an impingement tube to cool the suction wall and the pressure wall of a mid portion of an airfoil. The impingement tube is formed to not have impingement holes on an end of the impingement tube spaced toward the trailing edge along the suction wall. Impingement holes are formed in the same portion on a side of the impingement tube facing the pressure wall. Pedestals extend from an inner face of the suction wall toward the impingement tube in this area. The use of the pedestals over this area provides greater cooling to a focused area on the suction wall of the airfoil that might otherwise receive inadequate film cooling.

  • Publication number: 20070166161
    Abstract: A turbine airfoil includes an outer wall and a plurality of cooling passages or minicores formed in the outer wall. A web separates each adjacent pair of the minicores. In order to provide more effective, even cooling of the airfoil, a baffle inside the airfoil includes a plurality of outlets aligned with the webs. The fluid outlets direct the cooling fluid directly onto the web. The cooling fluid then flows through the minicores and out through exits in the minicores.
