Primary flight controls () for main and/or tail rotors () of helicopters with electro-mechanical interface between any of fly-by-wire and/or fly-by-light controls and hydraulic servo actuators () for control force amplification towards said main and/or tail rotor controls (). For each of the main and/or tail rotor controls () there is provided but one of the hydraulic servo actuators (), connected by one mechanical linkage () to one electro motor (), said one hydraulic servo actuator () being of the type having the one mechanical linkage () connected to its input () and its output () and the one electro motor () being of the direct drive type, the position of said electro motor () having a reference to said one mechanical linkage () and the torque delivered by said electro motor () to the hydraulic servo actuator () being related to the power consumption of said electro motor ().

Primary flight controls

For emergency piloting of a manual flight control system () of an aircraft (), in the event of flexible connection means () breaking, an upstream control device () takes authority over the electronic control unit () of series actuator (). An output pivoting quadrant () is subjected by a centering rod () to a blocking and centering action. In the event of the system breaking, the output pivoting quadrant () forms a bearing point for the series actuator (), so that an emergency control actuate a airfoil surface ().

Emergency piloting by means of a series actuator for a manual flight control system in an aircraft

A device for assisting the piloting of a rotorcraft, the rotorcraft having a flight control () for controlling a rotor () via at least one linkage (. An additional force is generated by at least one piloting assistance means () mechanically linked to the linkage (. The additional force is a function of the position of the flight control () and of an instantaneous force as measured on the linkage ().

Device for assisting the piloting of a rotorcraft

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