A closer coupling of wing aeroelasticity and flight control systems in the design process opens new opportunities to explore previously unviable designs. Common methods and tools across the disciplines also provide a way to rapidly adapt existing designs into derivative aircraft, at a reduced technological risk (e.g. using control to solve a flutter problem discovered during development). Flutter Free FLight Envelope eXpansion for ecOnomical Performance improvement (FLEXOP) thus opens a complete new dimension for derivative aircraft design. In order to validate the different methods and tools developed in this project, a flight test campaign is planned, in which the design and manufacturing of stiff wings (-0), very flexible wings (-1) with active flutter control, as well as tailored wings (-2) for passive loads alleviation will be verified. At the end of FLEXOP the concept for cost efficient wing stretch will be demonstrated in a scale-up task. The resulting derivative aircraft will have an extended wingspan by retrofit on the wings, tailoring modifications in the wing structure, flutter mode control, as well as increased payload.
