Workshop on Nonlinear Aeroelasticity and Flight Dynamics of Very Flexible Aircraft

13 November 2014, 10.00 AM - 13 November 2014, 10.00 AM

Venue: Engineers' House, Clifton, Bristol Speaker: Carlos Cesnik, University of Michigan, IAS Benjamin Meaker Visiting Professor

At Engineers’ House, The Promenade, Clifton Down, Bristol BS8 3NB

For highly efficient long duration flight, optimum configurations present longer wingspan than typically seen in traditional aircraft. Examples of such are found on high-altitude, long-endurance (HALE) aircraft and future “green” commercial transport aircraft designs. The requirements lead to geometrically nonlinear wing deformations, making aeroelastic-coupled-flight-dynamic considerations even more critical in the design cycle due to the inherent nonlinear nature of the problem.

This two-day workshop, lead by Carlos E. S. Cesnik, will discuss a range of techniques for geometrically-nonlinear modelling and simulation in this new flight regime, along with the needs and challenges involved in experimental characterization. A mix of lectures and group discussions will be used to better explore the issues in this important new direction for aircraft development.

Carlos Cesnik is a Professor of Aerospace Engineering and the Director of the Active Aeroelasticity and Structures Research Laboratory ( at the University of Michigan, USA, and is currently the Benjamin Meaker Visiting Professor at the University of Bristol. His research interests have focused on computational and experimental aeroelasticity of highly flexible wings, coupled nonlinear aeroelasticity and flight dynamic response in high-altitude long-endurance (HALE) aircraft and hypersonic vehicles, bio-inspired micro air vehicle (MAV) aeroelasticity, and active vibration and noise reductions in helicopters. Before his appointment at the University of Michigan, Prof. Cesnik was the Boeing Assistant/Associate Professor of Aeronautics and Astronautics at MIT, USA, after working as a research engineer at EMBRAER (Brazil). Professor Cesnik is a Fellow of the American Institute of Aeronautics and Astronautics (AIAA) and the Royal Aeronautical Society (RAeS).

This workshop is part of the Marie-Curie ALPES (Aircraft Loads Prediction using Enhanced Simulation) Initial Training Network, a four-year project to develop improved aircraft loads modelling and prediction.  There are currently five researchers based at the University of Bristol and Siemens who are part of the project.
