Abstract
An exemplary igniter assembly for a turbomachine includes an igniter extending along an axis from an igniting end portion to an opposing end portion.

Claims16
An igniter assembly for a turbomachine, comprising:
- an igniter extending along an axis in a first direction from an igniting end portion to an opposing end portion, wherein the igniting end of the igniter is configured to be received within a bore of a tube;
- a post mounted on the igniter and extending radially through the tube;
- a spring located radially outside the tube that biases the post in the first direction and that applies a force against the tube in a second direction opposite the first direction;
- and
- an annular seal restricts flow between the igniting end and the tube.

An augmentor assembly, comprising:
- an inner turbine exhaust case;
- a collar extending along an axis from the turbine exhaust case, the collar configured to receive a radially inner end of an igniter;
- an axial lock having a post that is biased against a slot wall to restrict movement of the igniter relative to the collar along the axis;
- and
- a spring positioned axially between a stop and a post, the spring biasing the post against the slot wall, wherein the stop extends radially outward from the collar.
