An electromechanical rudder system control using electromagnetic actuators provides dual redundancy to comply with safety demands. Diversity of possible interconnection distribution allows the manufacturer to choose the proper configuration to satisfy aircraft safety design, hardware savings and overall system quality improvements. A dual channel rudder system architecture includes reconfigurable electronic controllers used to control plural electromechanical primary actuators for rudder control, and a distribution of aircraft and cockpit sensors through the electronic controllers to guarantee minimum required safety standards in case of loss of input data. The plural electromechanical actuators driving a rudder surface are arranged in independent and redundant load paths.

Rudder system architecture for electrical actuators

A flexible distributed multi-system architecture for aircraft control integrates electronic computers comprising plural types of high integrity, dissimilar, generic and reconfigurable controllers (GECs) that can assume different purposes. GECs are configured as actuator controllers (able to control up to three channels including hydraulic or electro-mechanical actuators) or as Control Law Computers (able to calculate more sophisticated and processor demanding control laws). The multi-system architecture is built around a backbone of high performance, high integrity digital protocols and three hubs with dual connection to two different GECs.
