A variable geometry combustor having a combustor liner that defines at least one dilution port in order to provide air to a dilution zone within the combustor. At least one valve is positioned adjacent the dilution port for controlling the flow of air through the dilution port wherein the valve is settable to maintain one of a plurality of different open configurations.

Variable geometry combustor

A fuel injection apparatus () for a gas turbine engine () comprising a prefilmer (), the prefilmer () comprises a body (), the body () defines an axis (), an annular surface () and a downstream edge (), the prefilmer () arranged so that when working in operative association with the fuel injection apparatus () fuel impinges on the surface () and flows, by means of a passing airflow, to the downstream edge (), from where the fuel is shed, characterized in that the fuel injector () further comprises a means for circumferentially varying the residence time of the fuel across the surface ().

Fuel injection apparatus

A variable geometry pre-mixing fuel injector () for injecting a fuel/air mix in a downstream direction, comprising: an air inlet (); a fuel inlet () positioned downstream of the air inlet (); a duct () extending at least downstream of the fuel inlet () to define a fuel and air pre-mixing zone (), that narrows to form an opening (); and means for varying the flow of fuel/air mix from the pre-mixing zone () through the opening ().
