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.
