Riassunto analitico
Past work on JoinedWings pointed out the importance of including structural geometric
nonlinearities since the early stages of the design. However, the attention was mainly
focused on conservative loadings and several open questions needed an answer. In a effort
to simulate aerodynamic-pressure-like loads, this research focuses on non-conservative follower
forces. Several numerical evaluations demonstrate that follower loadings exacerbate
the risks of snap-instability in Joined Wings. The use of dynamical nonlinear approach it is essential to highlight the main issues in the design of the Joined-Wings. Finally, real aerodynamic forces have been used to study some particular configurations to mimic the real loading conditions of the wings.
