Abstract: A method and system for fuel nozzle cleaning during engine operation is provided. The steps or operations include operating the compressor section to provide the flow of oxidizer to the combustion chamber, operating the fuel system at a first fuel flow condition, in which the first fuel flow condition provides a fuel-oxidizer ratio at the combustion chamber, operating the fuel system at a second fuel flow condition, in which the second fuel flow condition provides the fuel-oxidizer ratio at the combustion chamber equal at the first fuel flow condition and the second fuel flow condition, and operating the fuel system at a third fuel flow condition after operating the fuel system at the second fuel flow condition.

Abstract: A method and system for cleaning a fuel nozzle during engine operation is provided. Operations include operating the compressor section to provide the flow of oxidizer at a first oxidizer flow condition to the combustion chamber, wherein the first oxidizer flow condition comprises an environmental parameter; operating the fuel system at a first fuel flow condition to produce a fuel-oxidizer ratio at the combustion chamber; comparing the environmental parameter to a first environmental parameter threshold; and transitioning the fuel system to a second fuel flow condition corresponding to a cleaning condition at the fuel nozzle if the environmental parameter is equal to or greater than the first environmental threshold.

Abstract: A method for measuring shaft deflection in a turbomachine includes communicating one or more signals from a controller to a plurality of sensing devices positioned on a shaft of a turbomachine across an airgap defined between a rotating antenna positioned around the shaft and a stationary antenna aligned with the rotating antenna in a radial direction to excite the plurality of sensing devices; receiving a parameter of the shaft in a plurality of circumferentially spaced locations from the excited plurality of sensing devices; determining a magnitude of a deflection in the shaft as a function of the parameter of the shaft in the plurality of circumferentially spaced locations; and adjusting a startup sequence or a motoring sequence of the turbomachine based on the magnitude of the deflection
