    Abstract: A torch igniter for a combustor of a gas turbine engine includes an igniter body and an igniter head. The igniter body is disposed within a high-pressure case of a gas turbine engine and extends primarily along a first axis, and includes an annular wall and an outlet wall. The annular wall surrounds the first axis and defines a radial extent of a combustion chamber therewithin. The outlet wall is disposed at a downstream end of the annular wall, defines a downstream extent of the combustion chamber, and includes an outlet fluidly communicating between the combustion chamber and an interior of the combustor. The igniter head is removably attached to the igniter body at an upstream end of the annular wall, wherein the igniter head defines an upstream extent of the combustion chamber, and includes an ignition source and a fuel injector.

    Abstract: A swirler for inducing swirl on a liquid flow includes a swirler body defining a downstream end and an upstream end; a plurality of axial slots on an external surface of the swirler body, each of the plurality of axial slots having a slot entrance and a slot exit; and a slot relief at the slot exit. Each of the plurality of axial slots are helical and configured to impart swirl on the liquid flow as the liquid flow traverses through each of the slots.
