Abstract
A combustor seal system for a gas turbine engine is provided that includes a rear inner discharge nozzle (RIDN) configured to engage a liner of a combustor. The system further includes a nozzle guide vane (NGV) positioned adjacent the RIDN. The NGV and the RIDN together define a cavity. The system further includes a seal in contact with the RIDN and positioned in the cavity. The seal curves along a surface of the cavity and contacts the RIDN at a first point and a second point in the cavity. The seal contacts the NGV at a third point.

A combustor seal system for a gas turbine engine, the system comprising:
- a rear inner discharge nozzle (RIDN) configured to engage a liner of a combustor;
- a nozzle guide vane (NGV) positioned adjacent the RIDN, wherein the NGV and the RIDN together define a cavity;
- and
- a seal in contact with the RIDN and positioned in the cavity, wherein the seal curves along a surface of the cavity and contacts the RIDN at a first point and a second point in the cavity, and the seal contacts the NGV at a third point.
A combustor seal assembly for a gas turbine engine, the assembly comprising:
- a seal comprising a first end, a second end, and a seal body extending between the first end and the second end;
- a rear inner discharge nozzle (RIDN) comprising an upstream portion and a downstream portion relative to a primary flow path of the gas turbine engine;
- and
- a nozzle guide vane (NGV), wherein the NGV is positioned adjacent the RIDN, the RIDN and the NGV together defining a cavity, wherein the seal is positioned in the cavity, wherein the seal curves along a surface of the cavity, wherein the seal contacts the upstream portion of the RIDN at a first point and a second point, and the seal contacts the NGV at a third point.
A method of assembly of a combustor seal system, the method comprising:
- providing a rear inner discharge nozzle (RIDN), the RIDN comprising an upstream portion and a downstream portion relative to a primary flow path of a gas turbine engine;
- positioning a seal on the RIDN, the seal comprising a first end, a second end, and a seal body extending between the first end and the second end;
- and
- positioning a nozzle guide vane (NGV) and the RIDN adjacent to each other, the RIDN and the NGV together defining a cavity, wherein the seal is positioned in the cavity and curves along a surface of the cavity, wherein the seal contacts the upstream portion of the RIDN at a first point and a second point, and wherein the seal contacts the NGV at a third point.
