In this paper, the buckling driven non-linear response is used to passively alleviate dynamic gust load. A novel aeroelastic framework is used to simulate the non-linear stiffness behaviour through a time-marching simulation that evaluates the dynamic response and the load alleviation achieved. The results show how the buckling can be tailored to alleviate the load and to save structural mass.
