  • Modular fuel nozzle assembly for gas turbine engines
    Patent number: 4938418
    Abstract: A modular fuel nozzle assembly includes a precalibrated, stand-alone valve module having a fuel metering valve and a precalibrated, stand-alone nozzle module having a fuel injection nozzle. The valve module and nozzle module include separate support housings joined together at an interface between the two modules to facilitate manufacturing, testing and maintainability of the fuel nozzle assembly. Fuel tubes extend across the interface to interconnect fuel passages in the joined modules.

  • Reduced coking of fuel nozzles
    Patent number: 4798330
    Abstract: Coking of the hot external face of fuel nozzles operating in the combustor of a gas turbine engine is reduced by controlling air discharging from the nozzle face in a manner to provide a recirculation zone spaced away from the nozzle face a distance effective to substantially reduce coking and yet maintain a stable flame front in the combustor.
