Abstract:
1. A fuel injector for a gas turbine engine comprising: a) a feed arm having a fuel inlet fitting for delivering fuel to at least one fuel conduit extending through the feed arm; b) a nozzle body depending from the feed arm having a pilot fuel circuit and a main fuel circuit outboard of the pilot circuit extending therethrough, wherein the pilot fuel circuit and the main fuel circuit are configured and adapted to receive fuel from the feed arm and to issue fuel from an exit orifice of the nozzle body; and c) sensing means configured and adapted to provide temperature feedback in order to control fuel flow in at least one of the main and pilot fuel circuits to maintain fuel temperature within a predetermined range, wherein the sensing means are in a swirler housing of the nozzle body adjacent to at least one of the main and pilot fuel circuits for sensing fuel temperature.
