The paper concerns the technology of the design, realization, and testing of a flexible smart
wing in a wind tunnel equipped with a turbulence generator. The system of smart wing …

Flutter is an unstable oscillation caused by the interaction of aerodynamics and structural
dynamics. It is current practice to operate aircraft well below their open-loop flutter speed in …

The paper presents the control design approaches for the European research project
FLEXOP. The ultimate goal is to develop and apply active flutter suppression and load …

The paper details the research and corresponding implementation and testing steps of the
FLEXOP demonstrator aircraft. Within the EU funded project an unmanned demonstrator …

The model-based flight control system design for a highly flexible flutter demonstrator,
developed in the European FLEXOP project, is presented. The flight control system includes …

The paper proposes a control design methodology for active flutter suppression for the
aeroservoelastic (ASE) aircraft of the European project FLEXOP. The aim of the controller is …

Structural weight reduction and high aspect ratio wings play a key role in improving the
performance of modern transport aircraft. This leads to a highly flexible aircraft structure …

For many dynamical systems, it is required to actively control individual modes, especially
when these are lightly damped or even unstable. In order to achieve a maximum control …

The present thesis is the result of my work at the Institute of System Dynamics and Control at
the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany. My thanks go to Prof …

The flutter phenomenon is a potentially destructive aeroelastic vibration studied for the
design of aircraft structures as it limits the flight envelope of the aircraft. The aim of this work …
