  • Thrust margin monitoring device for rotorcraft, rotorcraft and corresponding method
    Patent number: 11623741
    Abstract: A device for monitoring an available thrust margin of an anti-torque member of a rotorcraft as a function of flight conditions, said rotorcraft comprising a power plant driving at least one main rotor participating at least in the lift of said rotorcraft, said anti-torque member participating in the control of the yaw movements of said rotorcraft.

  • Rotorcraft having an airspeed sensor located at the top of a tail fin of the rotorcraft
    Patent number: 9415881
    Abstract: A method of calculating and displaying the true airspeed of a rotorcraft. At least one omnidirectional airspeed sensor is installed at the top of a tail fin of the rotorcraft. The true airspeed of the rotorcraft flying at speeds that are lower than or equal to at least one airspeed threshold of the rotorcraft is calculated by correcting the measurements supplied by the airspeed sensor installed at the top of the tail fin as a function of the effects produced by the air stream generated by rotation of the main rotor of the rotorcraft on the characteristics of the speed of the air stream measured by the tail fin airspeed sensor. For this purpose, a correction rule calibrated in test flight is advantageously applied to correct the measurements supplied by the airspeed sensor installed at the top of the tail fin.
