Research and Analysis on modeling method of Tandem wing UVA

According to the aerodynamic structure characteristics and control scheme of tandem wing small cruise missile, based on the analysis of the advantages of tandem wing layout, the trajectory simulation model and guidance control simulation model are established; Taking lift as an example, the ballistic model focuses on the method of obtaining lift coefficient and thrust model; The guidance and control model is modeled in sections according to the flight characteristics of different stages; Finally, it can provide a certain reference for the simulation of the change of the trajectory angle and the deflection angle of the UAV, and provide the correct simulation results for the application of this kind of guidance technology.
