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.

An igniter tube assembly includes an igniter, an igniter tower with a radially extending portion, a ferrule with a radially extending portion, and a retainer with a radially extending portion. The ferrule and retainer capture the radially extending portion of the igniter tower and sealing surface provides an area for the ferrule to interface with the igniter tower. The igniter moves relative to the casing in which it is secured while a fluid seal between the igniter and ferrule controls air flow.

Inverted cap igniter tube

A combination including a gas turbine engine extending along an axis is disclosed herein. The gas turbine engine includes an annular combustor having a combustor liner. The combination also includes a plurality of projections extending from the combustor liner and spaced from one another circumferentially about the axis. The combination also includes a free-standing ring disposed about the combustor liner and positioned adjacent to the plurality of projections along the axis. The plurality of projections engage the free-standing ring and circumferentially support the combustor liner while allowing relative radial displacement between the combustor liner and the free-standing ring. The combination also includes a plurality of pins each being integrally-formed with one of the plurality of projections. Each of the plurality of pins extends along the axis and is received in one of a plurality of slots formed in the free-standing ring.
