Riassunto analitico
Past work on JoinedWings pointed out the importance of including structural geometric<br>nonlinearities since the early stages of the design. However, the attention was mainly<br>focused on conservative loadings and several open questions needed an answer. In a effort<br>to simulate aerodynamic-pressure-like loads, this research focuses on non-conservative follower<br>forces. Several numerical evaluations demonstrate that follower loadings exacerbate<br>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.<br>
