    Abstract: A fluid flow control apparatus includes first and second bodies, an inlet, and an outlet. The first body includes a slot, and the second body includes a vortex chamber. The second body is moveable relative to the first body to align the slot and the vortex chamber. The vortex chamber includes a chamber inlet section, an orifice, and a tapered section that has a frustoconical shape and tapers from the chamber inlet section to the orifice. The chamber inlet section is in fluid communication with the slot when the vortex chamber is aligned with the slot. The inlet is in fluid communication with the slot, and the outlet is in fluid communication with the orifice.

    Abstract: A swirler includes a swirler body defining a diverging upstream surface defining a longitudinal axis and a plurality of swirl vanes extending from the diverging upstream surface. The swirl vanes are angled to impart swirl around the longitudinal axis on a fluid flow over the diverging upstream surface. An airblast injector includes a swirler as described above, and a nozzle body defining an air passage therethrough along the longitudinal axis with a diverging outlet. The swirler is operatively associated with a diverging outlet of the nozzle body. An annular swirler outlet area can be defined between downstream ends of the swirler and diverging outlet of the air passage. A throat area can be defined in the air passage upstream of the diverging outlet thereof. The swirler outlet area can be greater than the throat area.

    Abstract: A fuel injector system for a torch igniter includes an injector body centered on an axis, a receiving aperture formed in a cap of the torch igniter, an injector aperture, an air channel, a fuel channel, and a purge passage formed in a housing of the torch igniter and fluidly connected to a cooling air source. The injector body includes an axial wall at a first axial end of the injector body, an outer wall connected to the axial wall and extending along the axis transverse to the first wall, and an inner portion connected to the axial wall and extending along the axis transverse to the axial wall. An outer surface of the inner portion is spaced a distance from an inner surface of the outer wall, forming an insulating space between the outer wall and the inner portion.

    Abstract: An embodiment of a torch igniter for a combustor of a gas turbine engine comprises a combustion chamber oriented about an axis, a cap defining an axially upstream end of the combustion chamber and oriented about the axis, a tip defining an axially downstream end of the combustion chamber, a structural wall coaxial with and surrounding the igniter wall, an outlet passage defined by the igniter wall within the tip, and a cooling system. The cooling system comprises an air inlet formed within the structural wall, a first flow path disposed between the structural wall and the igniter wall, and an aperture extending through the igniter wall transverse to the flow direction. The aperture directly fluidly connects the first flow path to the combustion chamber.

    Abstract: A torch ignitor system includes a torch wall defining a combustion chamber therein with a flame outlet passing out of the torch wall downstream of the combustion chamber. A fuel injector is mounted to the torch wall to issue fuel into the combustion chamber. At least one ignitor is mounted to the torch wall, positioned to ignite fuel issued from the fuel injector. A film cooler is defined through the torch wall and is operative to issue a film of cooling air from outside the torch wall along an interior surface of the combustion chamber for cooling the torch wall.
