An electromechanical inlet guide vane actuation system includes one or more electric motor driven actuators that are used to appropriately position the inlet guide vanes in a gas turbine engine. The actuation system includes a control circuit that supplies guide vane actuation control signals in response to guide vane position command signals it receives. The guide vane actuation control signals are supplied to one or more electric motors, which position actuators, and thus the inlet guide vanes, to the commanded position.
We claim: 1. A variable inlet guide vane actuation system, comprising a control circuit including a primary channel and a secondary channel, each channel adapted to receive one or more guide vane position control signals and operable, in response thereto, to selectively supply guide vane actuation control signals; a primary electric motor coupled to receive the guide vane actuation control signals from the primary channel and operable, in response thereto, to supply a drive force; a secondary electric motor coupled to receive the guide vane actuation co...
