  • Single-rotor helicopter having a compound anti-torque system, and a method of countering the torque induced by said single rotor
    Patent number: 5388785
    Abstract: A helicopter comprising: a single main rotor for forwards motion and for support; and an anti-torque system comprising: an auxiliary, anti-torque rotor rotated from the engine means of said main rotor and exerting controllable anti-torque lateral thrust; and at least one steering airfoil that is controllable in steering and that generates anti-torque transverse lift. According to the invention, the helicopter includes automatic swivel control means for automatically controlling the swivel angle of said steering airfoil as a function of the collective pitch angle of said main rotor and of the forward speed of said helicopter.
