Modeling of an innovative actuation system for high lift devices and its control logics.

The aim of this thesis is to analyse the applicability of an electric actuation system to control the secondary moving surfaces of a business jet, specifically the Lockheed Jetstar. In the study, different mechanical irreversibility devices are implemented, including the No-Back Brake and the Wing-Tip Brake, in order to guarantee the safety of the system. The model of the actuation system, developed in the MATLAB/Simulink environment, is based on a non-distributed configuration of the high-lift devicet acuation system. Control logics were also modelled to manage and limit any asymmetries between the two sides of the wing during the operation of the secondary moving surfaces, a critical requirement for the design of actuation systems.
