Technology transfer of aircraft actuation to marine and propulsion

Abstract

The most flUlclamental concept in designing multi-lane smart electromechanical actuation systems, besides meeting performance requirements, is the realization of high integrity. The main aim of this paper is to discuss flUlclamental consolidation designs and monitoring schemes in different architectures and to address threshold settings methodologies, inherent randonmess, lane equalization, and control strategy. The analysis is based on a 4-lane actuation system capable of driving aerodynamic and inertial loads (with 2 lanes failed) of an aileron control surface similar to that of the Sea Harrier.
