Assignee: RTX CORPORATION
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F | IPC F

Claim 17:
18. An assembly for a turbine engine with a flowpath, comprising:
a fuel injection system including a fuel source, a fuel treatment device, a first fuel injector, a second fuel injector and an air swirler;
the fuel injection system configured to process supply fuel output from the fuel source to provide first fuel and second fuel, wherein the second fuel has a different composition than the first fuel, the fuel treatment device is configured to at least partially crack the supply fuel using a catalyst to provide the first fuel;
the first fuel injector configured to inject the first fuel into a cowl plenum upstream of a combustion chamber along the flowpath for combustion within the combustion chamber;
the second fuel injector configured to inject the second fuel into the flowpath at an inlet into the combustion chamber for combustion in the combustion chamber; and
the air swirler located at the inlet into the combustion chamber, and the air swirler arranged fluidly between the cowl plenum and the combustion chamber along the flowpath, wherein the first fuel injector is configured to inject the first fuel into a portion of the cowl plenum radially outboard of the air swirler.
