US 2012/0055163 A1 · FUEL INJECTION ASSEMBLY FOR USE IN TURBINE ENGINES AND METHOD OF ASSEMBLING SAME

Abstract

A method for assembling a fuel injection assembly for use in a turbine engine is provided. The method includes providing at least one cap member that has at least one first opening extending at least partially through it and at least one second opening extending at least partially through it. The method includes coupling a plurality of tube assemblies within the turbine engine. Each tube assembly includes a plurality of tubes. Moreover, the method includes coupling an injection system to the cap member to enable a fluid from a fluid source to be discharged through the at least one second opening. This fluid provides a barrier between adjacent tube assemblies to facilitate reducing dynamic pressure oscillations within the fuel injection assembly during turbine engine operation.
