Claims16
A system, comprising:
- a turbine engine, comprising:
- a combustor having a head end region;
- and
- a plurality of multi-nozzle assemblies, wherein each of the plurality of multi-nozzle assemblies comprises a plurality of swirl vane assemblies, each multi-nozzle assembly having a mounting base coupled to the head end region, wherein each multi-nozzle assembly comprises an inlet flow conditioner extending to the mounting base, the inlet flow conditioner comprises a load-bearing annular wall defining therethrough a plurality of air inlets, and the inlet flow conditioner structurally supports each multi-nozzle assembly at the mounting base, wherein each multi-nozzle assembly consists of a tri-nozzle that includes three fuel nozzles arranged in a generally triangular pattern.
