Abstract:
1. A torque resisting system for a helicopter which comprises a body, main rotor and a tail rotor, the system comprising: a deflector connected to an actuator for moving the deflector relative to the body, wherein the body comprises opposing lateral sides wherein only one lateral side of the opposing lateral sides is associated with the deflector such that the deflector is moveable to a position to extend away from the only one lateral side in a direction nonparallel to a longitudinal axis of the helicopter creating an imbalance of drag force on the helicopter between the only one of the lateral side compared to another lateral side of the opposing lateral sides, with the helicopter in motion; and a sensor operationally associated with the tail rotor and the actuator; wherein the actuator moves the deflector upon: receiving a signal indicating that the tail rotor is operating below a predetermined number of rotations for a given time period or sensing a loss of a signal from the sensor.
