초록 ▼

Gas turbine engine systems and methods involving enhanced fuel dispersion are provided. In this regard, a representative method for operating a gas turbine engine includes: providing a gas path through the engine; introducing a spray of fuel along the gas path downstream of a turbine of the engine;

대표청구항 ▼

1. A gas turbine engine comprising: a combustion section;an exhaust section located downstream from the combustion section, the exhaust section having an exhaust case and an augmentor assembly;the augmentor assembly having a nozzle and an airflow director, the nozzle being configured to receive fuel in a flow of fuel and to disperse the fuel, the airflow director being configured to direct a flow of air from the exhaust case toward the fuel dispersed from the nozzle such that interaction between the flow of air and the fuel dispersed from the nozzle further disperses the fuel;the augmentor assembly further including a first mounting component configured to position a fuel conduit with respect to a vane, a second mounting component configured to position the fuel conduit with respect to the vane, and an igniter extending through the first mounting component and contacting the second mounting component, the first and second mounting components defining the airflow director, wherein the airflow director includes a first aperture through which the fuel conduit is mounted and a first airflow gap defined between the fuel conduit and the mounting component at the first aperture and a second aperture through which the fuel conduit is mounted and a second airflow gap defined between the fuel conduit and the mounting component; andwherein the nozzle is directed toward the igniter such that fuel is dispersed toward the igniter from the nozzle. 2. The engine of claim 1, wherein the airflow director is positioned, at least partially, about the nozzle. 3. The engine of claim 1, further comprising cooling air apertures operative to direct cooling air toward a vicinity of the nozzle. 4. The engine of claim 3, wherein the exhaust section has a tail cone; and the air cooling apertures are located on the tail cone. 5. The engine of claim 1, wherein the vane extends across a gas path of the exhaust section, the nozzle being routed through at least a portion of the vane. 6. The engine of claim 1, wherein the engine is a turbofan gas turbine engine. 7. The engine of claim 1, wherein airflow through the aperture is aligned with a direction of the flow of fuel at the aperture. 8. The engine of claim 1, wherein fuel between said nozzle and an intersection of the flow of air and the fuel has a first magnitude of disbursement, and fuel downstream of the intersection between the flow of air and the fuel has a second disbursement, the second disbursement being greater than the first disbursement.
