Abstract
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; and impinging the spray of fuel with a relatively higher velocity flow of air such that atomization of the fuel is increased.
Claims11
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 assembly and an airflow director, the nozzle assembly being operative to receive a flow of fuel and to disperse the fuel, the airflow director being operative to direct a flow of air from the exhaust case toward the fuel dispersed from the nozzle assembly such that interaction between the flow of air and the fuel dispersed from the nozzle assembly further disburses the fuel;
- and
- the augmentor assembly further including a mounting component configured to position a fuel conduit with respect to a vane, and an igniter extending through the mounting component.

A method for operating a gas turbine engine comprising:
- providing a gas path through the engine;
- introducing a spray of fuel along the gas path downstream of a turbine of the engine, the spray of fuel originating from a fuel conduit positioned in a vane via a mounting component;
- impinging the spray of fuel with a relatively higher velocity flow of air such that atomization of the fuel is increased;
- providing an igniter extended through the mounting component;
- and
- igniting the spray of fuel using the igniter.
