A torque resisting device for a helicopter, wherein the helicopter includes a body and a main rotor. The device includes a deflector secured to and movable relative to the body, wherein the body includes opposing lateral sides and the deflector is movable to a position to extend away from only one of the lateral sides of the opposing lateral sides. The deflector includes a dimension extending in a plane generally non-parallel to a plane of the main rotor. Further included is a method for counteracting a torque created by the rotation of a main rotor of a...

1. A torque resisting device for a helicopter comprising: a body comprising opposing lateral sides, wherein only one of the opposing lateral sides comprises a deflector secured to and movable relative to the body such that the deflector is movable to a position to extend away from the one lateral side in a direction nonparallel to a longitudinal axis of the helicopter. 2. The torque resisting device of claim 1 wherein the deflector extends away from the body from a position between a main rotor and a tail rotor associated with the body. 3. The torque resisting device of claim 1 further including the deflector rotatably hinged to the body. 4. The torque resisting device of claim 1 wherein the deflector is movable to a deployed position with the deflector extended in a direction forming a desired angle relative to the longitudinal axis of the body with at least a portion of the deflector positioned spaced apart from the body. 5. The torque resisting device of claim 4 wherein the deflector has a non-deployed position with the deflector positioned without extending away from the body. 6. The torque resisting device of claim 5 wherein the deflector is positioned generally along an exterior portion of the body with the deflector in the non-deployed position. 7. The torque resisting device of claim 5 wherein the deflector comprises a portion of the body with the deflector in the non-deployed position. 8. The torque resisting device of claim 7 wherein the deflector is positioned generally flush with the body with the deflector in a non-deployed position. 9. The torque resisting device of claim 4 further comprising a rotation sensing device which senses a number of rotations over a period of time of a tail rotor which is associated with the body, wherein the sensing device is operatively associated with an actuator connected to the deflector such that the deflector is automatically moved to the deployed position with the sensing device sensing at least one of a specified decrease in number of rotations of the tail rotor over a period of time and senses no rotation of the tail rotor. 10. The torque resisting device of claim 9 wherein the sensing device comprises a tachometer. 11. The torque resisting device of claim 4 further comprising a deployment control device which is operatively associated with the deflector to automatically position the deflector to the deployed position at the desired angular relationship relative to the length of the body wherein the deployment control device is operatively associated with at least one of an air speed control device, directional gyro heading indicator, autopilot and Nav Aid. 12. The torque resisting device of claim 11 wherein the deployment control device comprises one of an electrically powered actuator and a hydraulic powered actuator. 13. The torque resisting device of claim 11 wherein the deployment control device comprises right and left pedals, the right and left pedal being operatively associated with the deflector such that an operator of the helicopter may position the deflector at a desired angular position relative to the length of the body by moving the right and left pedals. 14. A method for counteracting a torque created by the rotation of a main rotor of a helicopter, comprising the steps of: providing a body of the helicopter comprising opposing lateral sides wherein only one of the opposing lateral sides comprises a deflector secured to and movable relative to the body such that the deflector is movable to a position to extend away from the one lateral side in a direction nonparallel to a longitudinal axis of the helicopter; andmoving the deflector to extend away from the one lateral side of the body. 15. The method for counteracting a torque of claim 14 the step of providing further includes the deflector extending away from the body from a position between the main rotor and a tail rotor associated with the body. 16. The method for counteracting a torque of claim 14 the step of moving further includes positioning the deflector in a deployed position with the deflector forming a desired angle relative to the longitudinal axis of the body with at least a portion of the deflector positioned spaced apart from the body. 17. The method for counteracting a torque of claim 14 further including the step of sensing rotations of a tail rotor associated with the body wherein with the tail rotor under performing a predetermined number of rotations, the deflector is moved to extend away from the body. 18. The method for counteracting a torque of claim 14 the step of moving includes moving the deflector from a non-deployed position with the deflector not extending away from the body. 19. The method for counteracting a torque of claim 18 the step of moving includes the non-deployed position with the deflector generally aligned with the body. 20. The method for counteracting a torque of claim 14 further providing a deployment control device which is operatively associated with the deflector to automatically move the deflector to a deployed position at a desired angular relationship relative to the length of the body wherein the deployment control device is operatively associated with at least one of an air speed control device, directional gyro heading indicator, autopilot and Nav Aid. 21. The method for counteracting a torque of claim 20 wherein the step of providing a deployment control device comprises providing at least one of a hydraulic and electric actuator being operatively associated with the deflector. 22. A method for installing a device to counteract a torque created by the rotation of a main rotor of a helicopter wherein the helicopter comprises a body with opposing lateral sides, comprising the steps of: securing a deflector to the body such that the deflector is movable relative to the body to extend away from only one of the opposing lateral sides in a direction nonparallel to a longitudinal axis of the body, wherein the other of the opposing lateral sides is absent of another deflector secured to the body which would be movable relative to the body to extend away from the other of the opposing lateral sides in a direction non parallel to the longitudinal axis and such that deployment of the deflector would create an imbalanced drag on the helicopter with the helicopter in motion. 23. The method for installing a device to counteract a torque created by the rotation of a main rotor of a helicopter of claim 22 wherein the step of securing includes positioning the deflector between the main rotor and a tail rotor of the helicopter. 24. The method for installing a device to counteract a torque created by the rotation of a main rotor of a helicopter of claim 22 further including the step of securing one of an electrically powered actuator and hydraulically powered actuator to the deflector.
