  • Method for making and repairing effusion cooling holes in cumbustor liner
    Patent number: 9089933
    Abstract: A method for making or repairing a laser drilled hole in a component of gas turbine engines, to meet requirements of air flow through the hole, includes deformation of an excess material melted during the laser drilling process and remaining around an opening end of the hole, thereby causing a marginal reduction in an effective diameter of the hole.
    Type: Grant

  • GAS TURBINE COMBUSTOR REPAIR USING A MAKE-UP RING
    Publication number: 20100095525
    Abstract: A method of repairing a one-piece annular combustor of a gas turbine engine includes cutting through the combustor liner to separate the combustor into two pieces, repairing the combustor as desired, and then closing the combustor by using a make-up ring, which may be welded in place between the two pieces of the combustor. The make-up ring may be provided with an axial length selected such that an overall length of the combustor after the repair process is substantially equal to an initial overall length of the combustor before the repair.
