Abstract
A method for simulating an autorotation phase of a simulated rotorcraft. This method comprises a training phase carried out with a training rotorcraft comprising a single training combustion engine for rotating a training lift rotor. The training phase comprises assigning of a stored training value to a regulation limit, by a regulator, and regulation of the training combustion engine, by the regulator, keeping the torque parameter of the training rotorcraft less than or equal to the regulation limit, the training value being less than a nominal value, so that the training combustion engine produces a power equal to a reference power produced by a simulated electric motor.

A method for simulating an autorotation phase on a simulated rotorcraft comprising a single simulated combustion engine for rotating a simulated lift rotor when no failure has occurred and a simulated electric motor for rotating the simulated lift rotor during the autorotation phase,
- wherein the method comprises a training phase carried out with a training rotorcraft, the training rotorcraft comprising a single training combustion engine for rotating a training lift rotor, the training combustion engine being regulated by a regulator of a control system, keeping a torque parameter of the training rotorcraft less than or equal to a regulation limit, the training phase comprising:
- activation of the training phase by operating a human-machine entry interface of the control system;
- and
- in response to the activation, assigning of a stored training value to the regulation limit, by the regulator, and regulation of the training combustion engine by the regulator, keeping the torque parameter of the training rotorcraft less than or equal to the regulation limit, the training value being less than a nominal value assigned to the regulation limit prior to the activation, so that the training combustion engine produces a power equal to a reference power produced by the simulated electric motor during an autorotation phase in the simulated rotorcraft.
A method for simulating an autorotation phase on a simulated rotorcraft comprising a simulated turboshaft engine for rotating a simulated lift rotor when no failure has occurred and a simulated electric motor for rotating the simulated lift rotor during the autorotation phase,
- wherein the method comprises a training phase carried out with a training rotorcraft, the training rotorcraft comprising a training turboshaft engine for rotating a training lift rotor, the training turboshaft engine regulated by a regulator of a control system, keeping a torque parameter of the training rotorcraft less than or equal to a regulation limit, the training phase comprising:
- activating the training phase by operating a human-machine entry interface of the control system;
- and
- in response to the activating, assigning a stored training value to the regulation limit, by the regulator, and regulating the training turboshaft engine by the regulator, keeping the torque parameter of the training rotorcraft less than or equal to the regulation limit, the training value being less than a nominal value assigned to the regulation limit prior to the activating, so that the training turboshaft engine produces a power equal to a reference power produced by the simulated electric motor during an autorotation phase in the simulated rotorcraft.
