Abstract
A method for controlling combustor liner carbon formation on repaired combustors includes making modular effusion panel subassemblies remote from the combustor liner; removing a non-effusion or damaged panel from the combustor liner; and replacing the non-effusion or damaged panel with the modular effusion panel.
Claims26
A method of converting a non-effusion combustor liner to an effusion combustor liner comprising:
- removing at least one of a non-effusion inner panel and a non-effusion outer panel from said non-effusion combustor liner;
- and
- replacing said at least one non-effusion inner and outer panel with at least one of a modular inner effusion panel subassembly and a modular outer effusion panel subassembly, each subassembly including an effusion panel, and said modular outer effusion panel subassembly comprising six rows of first effusion holes proximate to one end of said effusion panel and wherein at least one of said six rows includes 239 first effusion holes and five rows of second effusion holes distal from said one end of said effusion panel and wherein at least one of said five rows includes 281 second effusion holes.
A method of converting a non-effusion combustor liner to an effusion combustor liner, comprising:
- making a first modular effusion liner panel subassembly remote from said non-effusion combustor liner;
- removing a first non-effusion liner panel subassembly from said non-effusion combustor liner;
- replacing said first non-effusion liner panel subassembly with said first modular effusion liner panel subassembly;
- wherein said first modular effusion liner panel subassembly includes:
- six rows of first effusion holes proximate to one end of said first effusion liner panel subassembly and wherein at least one of said six rows includes 239 first effusion holes;
- and
- five rows of second effusion holes distal from said one end of said first effusion liner panel subassembly and wherein at least one of said five rows includes 281 second effusion holes.
A method of repairing a combustor liner, comprising:
- making a first modular effusion panel of a first modular liner panel subassembly remote from said combustor liner;
- removing a first damaged panel from said combustor liner;
- replacing said first damaged panel with said first modular effusion panel;
- wherein said first modular effusion panel includes:
- six rows of first effusion holes proximate to one end of said first effusion panel and wherein at least one of said six rows includes 239 first effusion holes;
- and
- five rows of second effusion holes distal from said one end of said first effusion panel and wherein at least one of said five rows includes 281 second effusion holes.
A method of repairing a combustor liner, comprising:
- making a modular effusion panel of a liner panel subassembly remote from said combustor liner;
- removing a damaged panel from said combustor liner;
- replacing said damaged panel with said modular effusion panel;
- wherein said modular effusion panel comprises one of a first modular effusion panel and a second modular effusion panel;
- said first modular effusion panel including:
- six rows of first effusion holes proximate to one end of said first effusion panel and wherein at least one of said six rows includes 239 first effusion holes;
- and
- five rows of second effusion holes distal from said one end of said first effusion panel and wherein at least one of said five rows includes 281 second effusion holes;
- said second modular effusion panel including one of:
- four rows of third effusion holes and wherein at least one of said four rows includes 181 third effusion holes;
- and
- five rows of fourth effusion holes and wherein at least one of said five rows include 206 fourth effusion holes.
