Abstract
An igniter assembly () of a gas turbine () is presented, including an igniter () disposed within an igniter housing (). The igniter is extendable from the igniter housing through an opening () in a combustion liner () to an extended position, and is retractable from the extended position back through the opening to a retracted position (). The igniter assembly further includes a compressible assembly () disposed between a base () of the igniter housing and the combustion liner to form a sealed interface () with a perimeter () of the opening (). The compressible assembly is configured to restrict an air flow from passing between the igniter housing base and the perimeter of the opening. The compressible assembly is variable in length to accommodate a respective variation in a separation between the igniter housing base () and the opening ().
