Dynamic Modeling and Flight Simulation of a Folding Wing-Tip UAV

In this paper, a novel modeling method and the aerodynamic analysis of folding wing-tip UAVs are proposed. The folding wing-tip UAV models are established by treating the aircraft as a single body but relaxing the condition of rigidity. As a typical kind of folding wing-tip UAVs, NASA spanwise adaptive wing morphing UAV (SAW) is modeled and analyzed in this paper. The missile datcom is also applied to analyze the aerodynamic performance during the folding process of wing-tip by establishing the 3D model of the SAW and conducting numeric simulations.
