摘要： A gas turbine engine (10) includes a combustor (16) having a fuel nozzle assembly (24) for delivering fuel to a combustion chamber (20). A sensor (40) is at least partially housed within the fuel nozzle assembly (24) for sensing a parameter associated with the delivery of fuel to the combustion chamber (28). In one example, the sensor (40) is an optical sensor coupled to an optical decoder (42) for ascertaining the parameter. A trim valve (34) is in communication with the fuel nozzle assembly. A controller (44) is in communication with the sensor (40) and is programmed to actuate the trim valve (34) to adjust the amount of fuel delivered through the fuel nozzle assembly in response to the parameter. In one example, an end of the optical sensor (40) is arranged near a fuel exit (38) of the fuel nozzle assembly. The controller (44) actuates the trim valve (34) for the fuel nozzle assembly to achieve a desired air/fuel ratio and/or balance the fuel delivery of the fuel nozzle assembly relative to another fuel nozzle assembly within the gas turbine engine's combustor system.

摘要： A method of reducing the tendency of the combustion flame to attach to the centerbody of a tangential entry nozzle 10 is disclosed which comprises mixing fuel and air in a mixing zone 28 within a fuel nozzle assembly, thereby producing a first fuel/air mixture, which is isolated from the combustion products by maintaining sufficiently high axial velocities throughout the mixing zone. The nozzle has a longitudinal axis 26 and two cylindrical-arc scrolls 22,24 with the centerline of each offset from that of the other. Overlapping ends of these scrolls form an air inlet slot therebetween for the introduction of an air/fuel mixture into the fuel nozzle. A combustor-end endplate 18 has a central opening 20 to permit air and fuel to exit into a combustor, while at the opposite end another endplate 16 blocks the nozzle flow area. The scrolls are secured between these endplates. A centerbody 12 is located between the scrolls coaxial with the axis. The centerbody 12 has a base 58 which includes at least one air supply port extending therethrough, and an internal passageway 64. It includes a frustum portion (54) and aerodynamic ramps theat prevent flow reversal and flame stabilisation between the endplates 16,18.

摘要： A combustor panel (110) may include an attachment feature (106). Because conventional attachment features of conventional combustor panels may be insufficiently cooled, the present disclosure provides various combustor configurations for reducing hotspots in the vicinity of attachment features (106) and/or for providing cooling airflow to and in the vicinity of attachment features (106).

摘要： A combustor assembly (12) includes a convergent segment (34) followed by a divergent segment (36) to advantageously improve combustion. The combustor assembly includes a first segment (34) beginning at a forward end (24) that transitions to a second segment (36) past a transition segment (58) in a direction along a combustor axis (22) toward an aft end (26). The reduction in cross-sectional area within the first segment (34) provides desirable fuel and air mixing properties. The convergent first segment (34) in combination with the divergent second segment (36) decreases residence time of fuel-air mixture within the combustor chamber that decreases production of undesirable emissions from the combustor assembly.
