The coupled aeroelastic-flight dynamic response of very flexible aircraft to discrete lateral gusts is investigated using two independent state-of-the-art simulation and analysis frameworks. They are both built by coupling a geometrically-nonlinear composite beam finite-element discretization of the primary slender structures and a thin-surface unsteady vortex-lattice approximation to the potential-flow aerodynamic equations. Results are presented for the University of Michigan X-HALE unmanned aerial vehicle configuration, and show very good comparison between the two simulation tools, thus working as a partial verification of their implementation, while providing some new insights into the simulation requirements for complex nonlinear response of very flexible aeroelasticallydriven aircraft.
