UAV aircraft model for control system failures analysis

In the paper, influence of control surface failures on UAV aircraft dynamics is investigated. A method for control loads determination for a nonlinear UAV aircraft model is presented. The model has been developed to analyse the influence of various control surface failures on aircraft controllability and to form the background for developing reconfiguration methods of flight control systems. The analysis of the control system failure impact on the aircraft dynamics and the ability of the control system to reconfiguration are presented.
