Abstract
A fuel injector for a gas turbine combustor is disclosed which includes a feed arm having a flange for mounting the injector within the combustor and a fuel nozzle depending from the feed arm for injecting fuel into the combustor for combustion. An optical sensor array is located within the fuel nozzle for observing combustion conditions within the combustor.
Claims33
A fuel injector for a gas turbine combustor, comprising:
- a) a feed arm including means for mounting the injector within the combustor;
- b) a fuel nozzle depending from the feed arm for injecting fuel into the combustor for combustion, wherein the fuel nozzle includes a leading edge having a plurality of spaced apart viewing ports formed therein;
- and
- c) optical sensing means embedded in the viewing ports of the fuel nozzle for observing combustion conditions within the combustor.

A fuel injector for a gas turbine combustor, comprising:
- a) a feed arm including means for attaching the fuel injector to the combustor;
- and
- b) a fuel nozzle having an upstream end associated with the feed arm and a downstream end for issuing fuel into the combustor, the fuel nozzle including a leading edge having a plurality of spaced apart viewing ports containing an optical sensor array for viewing conditions within the combustor downstream from said nozzle.
A system for stabilizing combustion in a gas turbine engine, the system comprising:
- a) an optical sensing array embedded within a leadirnz edge of a fuel injector for observing conditions within a combustion chamber of a gas turbine engine;
- b) means for detecting combustion instabilities based upon conditions observed by the optical sensing array;
- and
- c) means for modulating a fuel flow rate to reduce detected combustion instabilities.
