Abstract: According to one embodiment, a rotorcraft includes a main rotor system, an anti-torque rotor system, an anti-torque rotor enhancement system, and an anti-torque rudder system. The anti-torque rotor enhancement system includes an aerodynamic structure having an opening therethrough and a support structure coupling the aerodynamic structure to the body of the rotorcraft such that the opening is positioned proximate to a rotation path of the at least one anti-torque rotor blade. The anti-torque rudder system includes at least one rudder surface operable to provide a second force on the body in the direction of rotation of the at least one main rotor blade.
