Abstract: An airblast fuel injector is provided for a fuel spray nozzle of a gas turbine engine. The injector has an annular air passage for the passage of a swirling air flow therethrough. The swirling air flow is used by the injector to produce an atomized fuel spray. The air passage contains a swirler for producing the swirling air flow, the swirler comprising a circumferential row of vanes which span inner and outer side walls of the air passage. Viewed on a longitudinal section through the injector, the air passage has a bend downstream of the swirler, the bend changing the direction of the air passage. The vanes are configured to introduce a radial component to the air flow exiting the swirler, the radial component guiding the air flow around the bend.

Abstract: Music Display, Collaboration, Annotation, Composition, and Editing (MDCACE) systems and methods are provided. Elements in music scores are presented as “layers” on user devices which may be manipulated by users as desired. For example, users may elect to hide or show a particular layer, designate a display color for the layer, or configure the access to the layer by users or user groups. Users may also create annotation layers, each with individual annotations such as music symbols or notations, comments, free-drawn graphics, staging directions, or the like Annotations such as staging directions and orchestral cues may also be generated automatically by the system. Real-time collaborations among multiple MDCACE users are promoted by the sharing and synchronization scores, annotations or changes. In addition, master MDCACE users such as conductors may coordinate or control aspects of the presentation of music scores on other user devices.
