    摘要： A liquid fuel injector includes a cylindrical center body including a center axis, an annular shroud concentrically disposed outside the center body, an annular fuel injection body disposed between and concentrically with the center body and the shroud, and including a fuel passage formed therein, a plurality of inner swirl vanes that are arranged in an equal cycle in an inner air passage between the center body and the fuel injection body, and are provided with an inner swirl vane action surface on an upstream side, a plurality of outer swirl vanes that are arranged in an equal cycle in an outer air passage between the fuel injection body and the shroud, and an outer swirl vane action surface on the upstream side.

    摘要： An object includes an annular outer body having an interior surface; and an annular inner body disposed inside the annular outer body, the annular inner body having an exterior surface defining an annular passage with the interior surface of the annular outer body. A plurality of suspension elements connects the interior surface of the annular outer body to the exterior surface of the annular inner body, each suspension element configured to substantially rigidly locate a position of the annular outer body relative to the annular inner body in axial and lateral directions while permitting controlled deflection in a radial direction. Each suspension element has an at least partially tear-shaped cross-section.

    摘要： A fuel injector comprises an elongate fuel passage (38) having an elongate axis extending from an upstream inlet end to a downstream outlet end. One or more outlets (38a) at an end of the passage extend obliquely with respect to the elongate axis. The elongate fuel passage is defined by an inner skin (35a) of a double skinned pipe, the double skinned pipe defining a first annular cavity (39) between the inner skin (35a) and outer skin (35). The inner skin (35a) and the outer skin (35) meet adjacent the one or more outlets (38a) to close an end of the first annular cavity (39). A second annular cavity (40) is defined by an annular outer wall (40a) extending from downstream of the passage end to a position downstream of the one or more outlets (38a). The fuel passage outlets (38a) emerge at a radially outer surface of the annular outer wall (40a). The annular outer wall (40a) is convergent at a downstream end whereby to define an orifice (40b) centred nominally coincident with the elongate axis. The annular outer wall (40a) may form part of an annular air swirler arranged nominally concentrically on the elongate axis.

    摘要： A nozzle includes a nozzle body defining a longitudinal axis and including a primary distributor and a secondary distributor. The primary distributor has an inner air passage fed by a radial swirler; a first fuel circuit radially outboard from the inner air passage with respect to the longitudinal axis; a second fuel circuit radially outboard from the first fuel circuit with respect to the longitudinal axis, wherein each of the first fuel circuit and the second fuel circuit extends from a respective fuel circuit inlet to a respective annular fuel circuit outlet; and an outer air passage defined between a fuel circuit outer wall and an outer air passage wall, wherein the outer air passage is a converging non-swirling outer air passage. The secondary distributor similar to the primary distributor is downstream of the primary distributor with respect to the longitudinal axis.
