Abstract: A gas turbine engine augmentor (72) nozzle has an inlet (104) for connection to an augmentor fuel conduit and an outlet (106) for expelling a spray of fuel. A passageway (110) between the inlet (104) and outlet (106) is at least partially bounded by outlet end surface portions (126,128) diverging from each other. The nozzle (70) may be used as a replacement for a non-divergent nozzle and may reorient a fuel jet centerline (150) toward radial.

Abstract: A tangential entry premixing fuel injector (10) for a gas turbine engine combustor includes a pair of offset scrolls (18) whose ends define a pair of entry slots (36) for admitting primary combustion air tangentially into a mixing chamber (28) bounded by the scrolls (18) and by longitudinally spaced endplates (14,16). An array of fuel injection passages (42) extends along the length of the slots. The passage array is configured to inject a primary fuel nonuniformly along the length of the air entry slots and to control the fuel penetration depth d in proportion to slot height H. The injector also includes a flame disgorging centerbody (48) having a bluff tip (54) longitudinally aligned with the injector's discharge plane (22) and a secondary fuel conduit (80) extending through the centerbody for discharging a secondary combustible fluid, preferably gaseous fuel, through a series of fuel discharge openings (84) in the tip (54). The flame disgorging centerbody improves fuel injector durability by resisting ingestion of combustion flame into the mixing chamber (28) and reliably disgorging any flame that is ingested.

Abstract: A cooling system for a turbine exhaust assembly 10 comprises an annular case 20, 21, a flow-path ring 12 and a splash plate or baffle 32. The flow-path ring 12 is coaxially disposed within the annular case 20, 21, and the splash plate or baffle 32 extends axially between the annular case 20, 21 and the flow-path ring 12. A plurality of cooling fluid apertures 31 are formed in the annular case 20, 21 in order to provide cooling fluid flow onto the splash plate or baffle 32. A plurality of impingement holes 33 are formed in the splash plate or baffle 32 in order to provide impingement cooling flow onto the flow-path ring 12. The flow-path ring may be provided with film cooling apertures 41 along the aft portion and/or the full axial length thereof. A blocker door 28 may be provided outside of the annular case 20, 21, downstream of the apertures 31, to increase a relative pressure of the cooling fluid flow. The annular case 20, 21 may comprise an inner turbine exhaust case or an outer turbine case.
