Abstract
A system for performing feed-forward anticipation of rotor torque demand on a helicopter engine is disclosed which includes a flight control computer adapted and configured to predict the total torque required at the main and tail rotors of the helicopter, and an engine fuel control system adapted and configured to compute the rate of change of the total torque, convert the rate of change of the total torque to an engine acceleration/deceleration rate, and obtain a demanded engine acceleration/deceleration rate therefrom.
