Investigation on the pitching moment non-linear characteristics of the high-attitude long-endurance (HALE) diamond joined-wing configuration unmanned aerial vehicle (UAV) was carried out by both numerical simulation and theoretical analysis method. The results show that the aircraft have two obvious pitching moment non-linear regions and there is a pitch-up phenomenon. The turbulent kinetic energy is used to represent the strength and the influence area of flow field structure of the aft-wing changed by the frt-wing wake direct sweep, which explains one of the causes of the non-linear region of the pitch moment. The other reason for the pitching moment non-linear region and pitch-up moment is explained by analyzing the separation characteristics of the aft-wing and the frt-wing. The influence of the general layout parameters of the UAV on the pitching moment characteristics of diamond joined-wing UAV was studied. The results show that adjusting the overall layout parameters can effectively mitigate the impact of pitching moment non-linear characteristics on flight performance.
