Method of assisting piloting, piloting assistance means, and a piloting assistance device for a rotorcraft using said piloting assistance means to implement said piloting assistance method
First Claim
1. A method of assisting the piloting of a rotorcraft, the rotorcraft having a flight control for controlling a rotor via at least one linkage, in which method, in order to generate an additional force with the help of piloting assistance means arranged in parallel with the linkage and also as a function of a setpoint force relating to the position of the flight control and an instantaneous force as measured on the linkage, the following steps are performed:
- measuring in real time an instantaneous force exerted on the linkage;
measuring the position of the flight control;
using at least one pre-established force relationship to determine a setpoint force that ought to be felt by the pilot operating the flight control when the flight control is at the measured position, and then determining the additional force to be equal to the difference between the setpoint force and the instantaneous force; and
determining the setpoint current to deliver to the piloting assistance means in order to cause the piloting assistance means to generate the additional force, and then electrically powering the piloting assistance means in compliance with the setpoint current.

Abstract
The present invention relates to a device and method of assisting the piloting of a rotorcraft, the rotorcraft having a flight control (10) for controlling a rotor (20, 21) via at least one linkage (35), during which method an additional force is generated by at least one piloting assistance means (100) mechanically linked to the linkage (35), the additional force being a function of the position of the flight control (10) and of an instantaneous force as measured on the linkage (35).
