The Rolls-Royce Model MT5S gas turbine engine was selected for use in the auxiliary turbine genset (ATG) of the DDG1000. This engine initially used the same fuel nozzle as the Model 501-K34 engine used in the DDG51 class ships. The Model MT5S can operate at higher powers levels and fuel flows. The fuel nozzle for the Model MT5S gas turbine engine experienced coking problems at the higher fuel flows. This paper discusses the investigation and solution to the problem to extend the operating range of the fuel nozzle for other applications.
