Aerodynamic Simulation of a Large Aspect Ratio Loitering Munition with Morphing Wings and Tails

In order to supply multifunctional requirements, aerodynamic numerical simulation is carried out for the new concept configuration of loitering munition. Firstly, the basic design features of the concept configuration are reviewed. Secondly, the numerical simulation method was validated and applied to the aerodynamic analysis of loitering munition. And then, the longitudinal and lateral aerodynamic performance of cruise and flights at variable speeds are simulated by numerical simulation method. Finally, the numerical simulation of rapid maneuvering flight was conducted and analyzed. The research shows that the loitering munition has good longitudinal and lateral static stability at multi-mode flight, which can achieve self-balancing. The cruise factor of the long endurance cruise mode and the maximum lift-drag ratio is greater than 20 respectively.
