Abstract
The present disclosure relates to a system for use with a gas turbine engine having a gas turbine shaft and an accessory gearbox drivably coupled to the gas turbine shaft. The system includes an accessory of the accessory gearbox. The system further includes an output shaft drivably coupled between the accessory gearbox and the accessory. The system further includes a sensor configured to generate a sensor signal. The system further includes a controller configured to determine a speed of the output shaft based on the sensor signal. The controller is further configured to determine a speed of the gas turbine shaft based at least on the speed of the output shaft.

A system for use with a gas turbine engine having a gas turbine shaft and an accessory gearbox drivably coupled to the gas turbine shaft, the system comprising:
- an accessory of the accessory gearbox;
- an output shaft drivably coupled between the accessory gearbox and the accessory;
- a sensor configured to generate a sensor signal indicative of a position of the output shaft;
- and
- a controller communicably coupled to the sensor, wherein the controller is configured to:
- determine a speed of the output shaft based on the sensor signal;
- and
- determine a speed of the gas turbine shaft based at least on the speed of the output shaft.
A method for use with a gas turbine engine having a gas turbine shaft and an accessory gearbox drivably coupled to the gas turbine shaft, the method comprising:
- determining a position of an output shaft drivably coupled between the accessory gearbox and an accessory of the accessory gearbox;
- determining a speed of the output shaft based on the position of the output shaft;
- and
- determining a speed of the gas turbine shaft based at least on the speed of the output shaft.
An apparatus for use with a gas turbine engine having a gas turbine shaft and an accessory gearbox drivably coupled to the gas turbine shaft, the apparatus comprising a controller configured to:
- determine a position of an output shaft drivably coupled between the accessory gearbox and an accessory of the accessory gearbox;
- determine a speed of the output shaft based on the position of the output shaft;
- and
- determine a speed of the gas turbine shaft based at least on the speed of the output shaft.
