摘要： A combustor structure of an embodiment is disposed to penetrate, from a direction perpendicular to an axial direction of a turbine rotor in a suprecritical CO2 gas turbine which uses supercritical CO2 for a working fluid, a casing of the suprecritical CO2 gas turbine. The combustor structure includes a plurality of combustors. Each of the combustors includes: a combustor liner in a cylindrical shape, which combusts fuel and an oxidant; a fuel supply part which is provided at an upstream end of the combustor liner and supplies the fuel into the combustor liner; and an oxidant supply part which is provided at the upstream end of the combustor liner and supplies the oxidant into the combustor liner.

摘要： A fuel injector for a gas turbine engine includes a feed arm defining a conduit extending between an inlet end and an outlet end and a plunger. The plunger is disposed within the conduit and is movable between a plunger first position and a plunger second position. A flow area defined between the plunger and the feed arm is smaller in the plunger first position than in the plunger second position to bias fuel flow through the fuel injector. Fuel systems, gas turbine engines, and methods of controlling fuel flow in gas turbine engine fuel systems are also described.

摘要： A fuel injector comprises one or more elongate fuel passages (802) having an elongate axis extending from an upstream inlet end to a downstream outlet end. One or more outlets (803) are provided at the outlet end and extend obliquely with respect to the elongate axis. The elongate fuel passage is defined by an inner skin of a double skinned pipe, the double skinned pipe defining a first annular cavity (804) between the inner skin and outer skin. The inner skin and the outer skin converge adjacent the one or more outlets (803) to form a nose (808). A bridge is arranged within the fuel passage (802) and upstream of the nose (808), the bridge comprising a plurality of arms (811) extending radially from a centre (812) to a wall of the fuel passage (802), the centre (812) arranged in axial alignment with a centre of the nose (808).

摘要： Fuel supplied to a rotary fluid trap is centrifugally accelerated within a first cavity adjacent a first side of a rotor, and is then directed though a plurality of first passages extending through the rotor between and proximate to the blades, and shaped so as to at least partially conform to the shape of the blades. Second passages extend within the blades from the first passages and terminate within associated cavities proximate to the tips of the blades. Relatively cooler fuel in the first passages is thermosiphon exchanged for relatively hotter fuel in the second passages so as to cool the blades. The heated fuel flows into a second cavity adjacent to a second side of the rotor and is discharged from the rotating frame of reference directly into the combustion chamber through a second rotary fluid trap. A separate fuel distribution circuit is used for starting and warm-up.

摘要： A fuel injector includes an annular nozzle housing circumscribed about a nozzle axis and an annular fuel nozzle circumscribed about the nozzle axis within the housing. The annular fuel nozzle has at least one main nozzle fuel circuit, a pilot nozzle fuel circuit, and spray orifices extending radially away from the main nozzle fuel circuit through the annular fuel nozzle. Spray wells extend radially through the nozzle housing and are aligned with the spray orifices. An asymmetric cyclone means is located radially outwardly of the housing for generating a swirling flow around the nozzle and an asymmetric static pressure differential around the housing. The asymmetric cyclone means may be a symmetrical radial inflow swirler circumscribed about a cyclone axis that is not collinear with the nozzle axis or may have a plurality of angled flow swirling elements angled with respect to and asymmetrically circumscribed about the cyclone axis.

摘要： An auxiliary power unit (APU) includes a rotary fuel slinger, and a single-spool, two-stage turbine. The rotary fuel slinger receives a rotational drive force from the turbine, and a supply of fuel from a fuel source. The rotary fuel slinger injects the fuel into a combustor as a continuous “fuel sheet.” As a result, fuel mixing and atomization inside the combustor is improved, which reduces emissions and pattern factor, which in turn increases turbine life.
