Abstract
A replacement method facilitates replacing of a portion of a nuggeted combustor liner within a gas turbine engine combustor in a cost-effective and reliable manner. The combustor includes a combustion zone that is defined by an inner and an outer liner. The inner and outer liners each include a series of panels and a plurality of nuggets formed by adjacent panels. The method includes the steps of cutting between an outer surface and an inner surface of at least one liner panel through at least one nugget, removing at least one panel that is adjacent the area of the liner that was cut, and installing a replacement panel into the combustor for each panel that was removed from the combustor.
Claims17
A method for replacing a gas turbine engine combustor liner panel, the combustor having a combustion zone formed by inner and outer liners, the inner and outer liners each including a series of panels and a plurality of cooling features, the cooling features formed by overhanging portions of the inner and outer liner panels, the cooling features between adjacent panels, a plurality of the panels including cooling nuggets, said method comprising the steps of:
- cutting through at least one panel nugget to remove at least one panel from the combustor;
- and
- installing at least one replacement panel into the combustor such that the series of panels are arranged in steps relative to one another.
A method for replacing a portion of a combustor liner within a gas turbine engine combustor, the combustor having a combustion zone formed by an inner and outer liner, the inner and outer liners each including a series of panels and a plurality of nuggets, the nuggets formed by adjacent panels, said method comprising the steps of:
- cutting between an outer surface and an inner surface of at least one liner panel nugget;
- removing at least one panel adjacent an area of the liner cut;
- and
- installing a replacement panel into the combustor to replace each panel removed from the combustor.
A method for replacing at least one deteriorated combustor liner panel within a gas turbine engine combustor including an annular liner including a multinugget region, a multihole region, and an inner surface, the liner including a plurality of nuggets, the multihole region extending downstream from the multinugget region, said method comprising the steps of:
- cutting through at least one nugget downstream from the at least one deteriorated combustor liner panel to be replaced and within at least one of the liner multinugget region and the liner multihole region;
- removing the at least one deteriorated combustor liner panel from the combustor;
- and
- welding at least one replacement panel to at least one existing panel within the combustor for each deteriorated combustor liner panel removed.
