    Abstract: A computer-implemented method for determining a scheduled maintenance session for a proportional actuator includes transmitting a command signal to a controller of the proportional actuator and generating, using the controller, a drive signal for controlling the proportional actuator using the command signal. The position of a component actuator of the proportional actuator is changed, on the basis of the drive signal, and the position of the component actuator is measured, using a sensor, and a position feedback signal is generated on the basis of the measurement. A condition indicator is estimated, with a processor, using only one of the command signal, the drive signal, or the position feedback signal. A health indicator is estimated, with the processor, using the condition indicator, and a scheduled maintenance session of the proportional actuator is determined, with the processor, using the health indicator.

    Abstract: Embodiments of a combined overspeed and fuel stream selector system are provided. In an embodiment, the assembly includes a conduit network, a Discharge Select Valve (DSV), and a shutoff valve. The DSV is fluidly coupled to a primary fuel inlet, a secondary fuel inlet, and a primary fuel outlet included in the conduit network. The shutoff valve is fluidly coupled between the primary fuel inlet and the primary fuel outlet. In a standard operation mode, the shutoff valve is maintained in an open position, while fuel received at the primary fuel inlet is directed through the shutoff valve, through the DSV, and to the primary fuel inlet. Conversely, in a backup operation mode, the shutoff valve is closed to block fuel flow from the primary fuel inlet to the primary fuel outlet, while the DSV directs fuel flow received at the secondary fuel inlet to the primary fuel outlet.
