    Abstract: An igniter assembly for a gas turbine combustor includes a first electrode, a second electrode, and an insulator. The first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a cross-sectional area of the outlet passage, and the cross-sectional area of the outlet passage is substantially constant along a longitudinal extent of the outlet passage. In addition, the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

    Abstract: The present application provides for ceramic collars and metal rings for active brazing in sodium-based thermal batteries. The ceramic collar may be an alpha-alumina collar configured for active brazing, and thereby sealing, to outer and inner Ni rings for use in NaMx cells. The portions of the alpha-alumina collar active brazed to the outer and inner Ni rings may be outwardly facing and include inwardly extending recesses. The portions of the outer and inner Ni rings active brazed to the outwardly facing portions of the collar may be inwardly facing. The alpha-alumina collar may include a greater coefficient of thermal expansion than each of the outer and inner Ni rings, and the alpha-alumina collar and outer and inner Ni rings may be configured such that a portion of the outer and inner Ni rings is deformed into the inwardly extending recesses of the alpha-alumina collar after active brazing thereof.

    Abstract: A combustor for a gas turbine system includes a combustor casing having an interior-establishing wall, and a chamber extending to the interior-establishing wall. In addition, the combustor includes an igniter assembly disposed within the chamber such that a tip of the igniter assembly is positioned radially outwardly from the interior-establishing wall. The igniter assembly includes a first electrode, a second electrode, and an insulator. In addition, the first electrode, the second electrode, and the insulator form a cavity, the second electrode forms an outlet passage extending from the cavity, a maximum cross-sectional area of the cavity is greater than a minimum cross-sectional area of the outlet passage, and the first electrode and the second electrode are configured to ionize gas within the cavity in response to an electrical current applied to the first electrode or to the second electrode.

    Abstract: The present disclosure relates to gas turbine engine operation in which an igniter assembly is provided with an electrical energy input (e.g., an electrical waveform) that is configured to increase a likelihood of igniting a fuel-air mixture surrounding the igniter assembly. In certain embodiments, the igniter assembly is supplied with an augmented electrical waveform that may reduce a quantity of sparks generated by the igniter assembly before successful light-off (e.g., ignition) of the fuel-air mixture is achieved (e.g., as compared to a quantity of sparks generated to achieve ignition by an igniter assembly that receives an electrical energy input in the form of a conventional electrical waveform). Accordingly, the augmented electrical waveform may reduce wear (e.g., via oxidation) on electrodes of the igniter assembly, such as a primary electrode (e.g., a center electrode) and a secondary electrode (e.g., an outer shell electrode) disposed about the primary electrode.
