Like issi noho said, a mighty impressive cv
. Which makes the above misunderstanding all the more interesting.
All turboprops I have flown had a cockpit gauge labelled "torque"; and a turbine powered helicopter still needs a tail rotor!
Torque can be thought of as the reaction to the angular momentum imparted to the airflow. Any propeller or rotor blade will develop torque, whatever sort of engine drives it.
