    Abstract: 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.

    Abstract: A tangential air entry fuel nozzle (10) has a combustor inlet port (20) to permit air and fuel to exit into a combustor (56). The port includes a convergent surface (116), a combustor surface, and a cylindrical surface (118) extending therebetween. The convergent surface extends a first distance along the longitudinal axis (26) of the nozzle, the cylindrical surface extends a second distance along the axis, and the second distance is at least 30% of the first distance.

    Abstract: A tangential air entry fuel nozzle 10 has a combustor inlet port 20 to permit air and fuel to exit into a combustor. The port includes a convergent surface 116, a divergent surface 117, and a cylindrical surface 118 extending therebetween. The convergent surface 116 extends a first distance along the longitudinal axis of the nozzle, the cylindrical surface 118 extends a second distance along the axis, and the second distance is at least 5% of the first distance.

    Abstract: A gas turbine engine (20) includes a high spool assembly (22) and a low spool assembly (26) each having a rotational axis (24, 28) that are spaced from one-another. The engine further includes a combustor (30) that may have a centerline (44) spaced from the rotational axes of each spool assembly (22, 26). Turning ducts (50, 52, 54, 56) of the engine are configured to re-direct airflow from one spool assembly (26) to the next and/or between one spool assembly (24, 26) and the combustor (30).
