<p>There is provided a counter-torque control assembly (60) for mounting to a tail boom (40) of a rotorcraft where the rotorcraft has a single main rotor (14), no tail rotor, and no tail fin. The assembly has an air intake chamber (62) with at least a first opening for receiving an air flow stream and a vane assembly (74) housed within the air intake chamber. The vane assembly (74) has at least two vane elements (76) capable of counter-rotation in the air flow stream. The assembly further has one or more microjet (80) propulsion devices coupled to a second end of the air intake chamber. The one or more microjet propulsion devices (80) draw the air flow stream over the vane elements (76) to generate a counter-torque force to counter a torque from the single main rotor (14).</p> |
