Urban environments are aerodynamically challenging for unmanned air vehicles (UAVs) because of complex flow structures and high levels of turbulence encountered around buildings. Therefore, studies have started focusing on the effects that gusting has on UAV aerodynamic performance. This study develops gust modelling capabilities towards understanding the aerodynamic response and more specifically gust mitigation strategies for UAVs operating in gusty urban environments. In particular, a radial basis function is applied to a modified split-velocity method for the numerical modelling of pitching wings for gust mitigation.
