Abstract
A gas turbine igniter includes an igniter rod disposed within a guide tube configured for travel between a hot-end region and a cold-end region and a cap connected to the guide tube, the cap defining an access passageway for the igniter rod. An attachment structure is provided for reducing the moment loading at the cold end of the igniter rod. The attachment structure has threaded outer surface configured to engage in a threaded connection with a threaded inner surface of the cap in an end portion of the cap that is proximate to the cold-end region, whereby the attachment structure is attachable to the end portion of the cap via the threaded connection. An inner surface of the attachment structure forms a guide surface for the igniter rod, at a reduced radial clearance with the igniter rod in comparison to the cap, proximate to the cold-end region.
