TO CERTIFYa new aircraft, it must be proved that it can withstand loads caused by turbulence and gusts [1]. According to the certification regulations [2, 3], two types of excitations have to be considered: discrete “1− cosine”(one minus cosine) gusts and continuous turbulence. In the first case, an aircraft model is excited with a single 1− cosine gust profile, the model outputs [eg, the wing root bending moment (WRB) or the vertical acceleration] are computed, and the simulation is repeated for several gust lengths. Moreover, the complete process has to be performed for many flight points such that the entire design envelope (defined by velocity, altitude, loading, etc.) is covered. Finally, the maximum and minimum peak of every output for all these simulations are used to define the limit loads due to discrete gusts. The other type of excitation, namely, continuous turbulence, considers the stochastic nature of turbulence …
