The directional stabilizer device and a rotor anti - torque carene and inclined, and a tail unit in a 'v' asymmetric and helicopter relates to such a device.

摘要

The directional and stabilizer device comprises a rotor anti - torque carene7, drives in rotation in a vein transversale9 provided carenage10 in an inclined on the vertical an angle ranging between 0 and 45. / p & & p & it comprises also a tail "- v" fixed to the top of the carenage10, and the two surfaces aerodynamiques15, 16 are extend of asymmetric with respect to the vertical plane passing through the top of the carenage10. The surfaces aerodynamiques15 et16 are incline according to the angular ranges between 0 and 45. / p & & p & application to the equipment of helicopters has a single rotor lift a mechanical drive.
