  • Patent number: 10190428
    Abstract: A seal for a gas turbine engine includes a top, a bottom, a left side, a right side, a back and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side. The top includes a first vane mating surface and the bottom includes a second vane mating surface.

  • Patent number: 10132176
    Abstract: A method of fabricating airfoil cluster includes providing an airfoil cluster that has a pair of spaced-apart airfoils that extend from a common platform wall. The airfoil cluster is then divided through the common platform wall to provide separate first and second airfoil segments. At least one cooling hole is then formed in at least one of the first and second airfoil segments. The segments are then metallurgically fused together in a distinct metallurgical joint in the common platform wall.

  • Publication number: 20170167381
    Abstract: A gas turbine engine component includes a body defining a cooling airflow passage thereat configured for directing a cooling airflow therethrough. A plurality of turbulators are positioned at at least one passage wall of the cooling airflow channel. Each turbulator of the plurality of turbulators includes a plurality of facets extending outwardly from a central portion. A gas turbine engine includes a combustor and a plurality of gas turbine engine components positioned in fluid communication with the combustor. Each component includes a body defining a cooling airflow passage thereat configured for directing a cooling airflow therethrough. A plurality of turbulators are located at at least one passage wall of the cooling airflow channel, each turbulator of the plurality of turbulators including a plurality of facets extending outwardly from a central portion.

  • Patent number: 9115591
    Abstract: A seal for a gas turbine engine is shown. The engine may have a first vane for imparting a first twist to air passing thereby and/or a second vane for imparting a second, different twist to air passing thereby, each of the first and second vanes having a mounting area for mounting the seal thereto. The seal includes a top, a bottom, a left side, a right side a back, and a front. The back is parallel to the front and the left side is parallel to the right side such that a non-square shape is formed by the intersection of the back, the left side, the front and the right side so that the seal may mate with the mounting area of the first vane and, if the seal is inverted, may mate with the mounting area of the second vane.
