Modeling and aerodynamic characteristics analysis of morphing aircraft

In recent years, military and civil aviation have put forward higher and higher requirements to the performance of the aircraft. The morphing aircraft can adapt to a variety of environments, perform a variety of tasks and meanwhile maintain excellent flight performance. This paper researches the dynamic modeling method, aerodynamic parameter analysis and the dynamic characteristic response of morphing aircraft. The physical model of a variable-span variable-sweep morphing aircraft was simplified so as to use Kane Equation modeling. In this paper, the software Datcom is used to analyze the aerodynamic parameters of the morphing aircraft. Then the aircraft's longitudinal dynamic responses during the morphing process are simulated and analyzed. The simulation results show that the speed, height and pitch angle of the morphing aircraft will be greatly changed.
