ABSTRACT:
A rotor for a gas turbine engine includes a turbine wheel with a centerbore therethrough, a main shaft projecting through the centerbore, a turbular stub shaft surrounding the main shaft at a turbine end of the latter and being rigidly connected thereto so that the stub shaft defines a radially spaced reverse flange on the main shaft, a tubular reference shaft around the main shaft having an output end rigidly connected to an output end of the main shaft and a turbine end rotatably journaled on an inside surface of the stub shaft, a plurality of axial slots in the stub shaft, a plurality of pole supports projecting radially from the reference shaft turbine end through the stub shaft slots, a plurality of first pole pieces on the pole supports, a plurality of second pole pieces on the stub shaft between the first pole pieces, and a stationary pick-up operative to develop an electrical signal proportional to the spacing between the pole pieces while the rotor rotates which spacing is proportional to rotor torque.
