Abstract
An air blast fuel injector for a gas turbine engine includes an elongate feed arm having an inlet fitting for receiving fuel and for distributing the fuel to first and second fuel delivery conduits extending through the feed arm. A nozzle body is operatively connected to the feed arm. The nozzle body includes an on-axis inner air circuit and fuel circuitry radially outboard of the inner air circuit for delivering fuel to a fuel swirler outboard of the inner air circuit. The fuel circuitry includes a first fuel circuit configured and adapted to deliver fuel to the fuel swirler from the first fuel conduit of the feed arm and a second fuel circuit configured and adapted to deliver fuel to the fuel swirler from the second fuel conduit of the feed arm.
