Popis: International audience; Reduction of aircraft environmental footprint has become over years a keyobjective for the industry. Particularly, for decades winglets have been proven to eficiently reduce drag and fuel consumption. However, the design of those wingtip extensions mainly relies on an aerodynamic shape optimisation for a given cruise condition resulting in suboptimal behaviour for the rest of the flight. Active winglet concept proposes to optimise the winglet cant angle along the flight to compensate the loss of eficiency inherent to fixed designs. The variation of winglet deflection impacts the lift distribution with repercussion on wing deformation that must be investigated. Besides, the presence of moving massesat the tip of the wing also has influence on dynamic response and particularly on flutter onset. This work proposes to evaluate those impacts through an aeroelastic analysis ofboth static and dynamic implications of active winglets combined with an aerodynamicperformances optimisation. The XRF1, an Airbus provided industrial standard multi-disciplinary research test case representing a typical configuration for wide body long-range aircraft, is used as the baseline aircraft. Coupled CFD/CSM computations areperformed to assess the evolution of wing shape with respect to winglets deflections and theconsequences on mission performance optimisation. While a parametric flutter analysisis carried-out to highlight the dependence of critical flutter speed on winglet cant angle.
