| Abstract: | A morphing aircraft could enhance its behavior and performance by varying its state. In this paper,a kind of tailless folding wing morphing aircraft research model was built. Based on this model, the change of folding wing longitudinal static stability in wing folding process was calculated by using the Vortex Lattice Method (VLM). Through aircraft longitudinal disturbulance equations, the states of wing folded and unfolded of short period mode and phugoid mode were obtained, and then their longitudinal dyn... |
