MechaTwing Summer School

we kindly invite you to our first Summer School from June 2 to June 6 as part of the project MechaTwing, funded by the European Union. We will bring together scientists and experts for lectures, workshops, and technical discussions with a focus on the aeroelastic and structural challenges in future aircraft design.Future transport aircraft are characterized by the urgent need to lower climate-damaging emissions. From the aircraft design point of view, new concepts, such as high aspect ratio wings, show great promise. They lower the induced drag significantly but implicate a number of aeroelastic challenges. The demanding aerodynamic design for transonic airspeeds and the high structural flexibility of high aspect ratio configurations require new methods for the multidisciplinary (aeroelastic) analyses and optimization. Nonlinearities are present in all the disciplines involved, and advanced control methods are required to ensure feasibility and safe operation (e.g. loads and flutter control). Also novel actuation technologies based on mechatronic systems which can drive control surfaces in limited space with high bandwidth are required. Various topics related to these challenges are treated in this summer school in terms of lectures and workshops, including experiments and the introduction of specific software:
