Beschreibung
Zusammenfassung:	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.
