Spreading and falling law of conductive fiber cluster moving in the air

To study spreading and falling law of the conductive fiber cluster, the trajectory model of the cluster was established. Based on the numerical calculation software of MATLAB, forth-order Runge-Kutta algorithm was used to write corresponding program, and the model was solved. Spreading and falling conditions of the clusters were tested by the ground scattering experiment and shooting range experiment, and the numerical calculation results are consistent with the experiment results, which proves that the model is reasonable. Numerical calculation results and test results provide references for determining scattering height of the shell, locating drop point of the cluster and further analyzing the damage efficiency to the target.
