摘要： A method for simulating an engine failure on a rotorcraft comprising several engines for setting a rotary wing in motion. The method comprises a training mode that comprises controlling each engine with a controller in order to simulate an engine failure, this control comprising limiting the power of each engine to a respective control restriction value. The training mode comprises the following steps: i) determining, with the controller, a maximum mass at least as a function of external conditions, and an initial mass of the rotorcraft at least as a function of an unladen mass of the rotorcraft, a mass of a crew present in the rotorcraft, and an estimated mass of fuel on-board; ii) comparing, with the controller, the initial mass with the maximum mass; and iii) determining, with the controller, each control restriction value as a function of the comparison.

摘要： A method of monitoring a first freewheel interposed between a first drive shaft of a first engine and a rotor. The state of operation of said first freewheel is correct if the first inlet speed of rotation of the first drive shaft lies in a second range of values corresponding to the current stage of operation while the outlet speed of rotation of the rotor lies in a first range of values corresponding to the current stage of operation.
