Abstract: A gas turbine engine and system for measuring torque for a gas turbine engine shaft is provided. The system may include a first sensor module, a second sensor module, a first coupler, a second coupler, and a static antenna. The first and second sensor modules may include strain sensors positioned on the gas turbine engine shaft. The first coupler may be positioned on the gas turbine engine shaft and electrically connected with the first sensor module. The second coupler may be positioned on the gas turbine engine shaft and electrically connected with the second sensor module. The static antenna may include a first band and a second band. The first signal band may be in operable communication with the first sensor module and positioned radially outward from the first coupler. The second signal band may be in operable communication with the second sensor module and positioned radially outward from the second coupler.

Abstract: A system for measuring torque for a gas turbine engine shaft is provided. The system can include a torque sensor positioned at an engine shaft. The torque sensor, itself, can include a strain sensor for obtaining a strain measurement of the engine shaft and a temperature sensor for obtaining a temperature measurement of the engine shaft. The system can also include a wireless communication element operably connected to the torque sensor for transferring the strain measurement and the temperature measurement. In addition, one or more memory storage units co-located with the torque sensor can be provided. The one or more memory storage units can store calibration information for the system. The calibration information is used by one or more processors to calibrate the strain measurement obtained by the strain and the temperature measurement obtained by the temperature sensor. Methods of using the system are also provided.
