Abstract: A fuel system includes an external cool air source, and a fuel injector. The fuel injector includes a fuel circuit, an outer air circuit, an inner air circuit, and an outlet. The fuel circuit receives liquid fuel from a fuel inlet. The outer air circuit receives cool air from the cool air source and substantially surrounds the fuel circuit. The inner air circuit is in fluid communication with the outer air circuit and a portion of the fuel circuit substantially surrounds the inner air circuit. The outlet provides atomized fuel from the fuel circuit, outer air circuit and inner air circuit to a combustor.

Abstract: A nozzle is provided including a fuel swirler having an outer wall, an interior wall, and a fuel flow path configured to receive a fuel flow. The fuel flow path extends from adjacent and inlet end of the nozzle to a discharge end of the nozzle and is arranged between the outer wall and the interior wall. The fuel flow path includes a first inlet portion and a volute. The first inlet portion is generally offset from a center of the fuel swirler.

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.
