Parameters Simulation and Optimization of Flying Net for UAVs Interception

As to the countermeasures of low, small and slow "black flying" UAV, the flying net launching technology scheme for anti-UAV based on reluctance electromagnetic launcher was proposed, and the working principle of the system was analyzed. For the nonlinear large deformation problem of flying net, the default beam element model and mechanical model of flying net were constructed, and the simulation analysis was carried out. Based on the orthogonal experimental method, the optimization analysis of flying net parameters was carried out, and based on the range analysis results, the sensitivity of armature initial velocity, armature mass and initial angle to the effective distance of flying net was obtained, as well as the optimization parameter combination. The flying net launching experimental system was established and validation experiments were carried out. The results show that the reluctance electromagnetic launching technology can be used to launch the flying net, and the flying net can effectively intercept the UAV. Furthermore, the initial angle of the armature has the greatest influence on the effective distance of the flying net, while the velocity of the armature has the least influence.
