Abstract
A device is described for determining the torque which is applied to a turbine shaft (10), the determination device having at least one system for contactless measurement of the integral torsion of the turbine shaft (10) and a unit for contactless measurement of the restoring constant of the turbine shaft (10). Furthermore, a method is described for determining the torque which is applied to the low-pressure turbine shaft (10) of a turbine engine, which is distinguished in that, to determine the torque, the integral torsion of the turbine shaft is measured by a contactless method and the restoring constant of the turbine shaft is measured.
