Study on Linear Shaped Charge Jet Penetrating into Double Layer Targets by orthogonal optimization

A new type of linear shaped charge structure (LSC) was designed to penetrate a hollow double layer target with certain plate thickness and spacing. First, we set up a range of LSC structure parameters, including liner cone angle and thickness, bus bar length and explosive charge. Then, we obtained the structure with parameters close to the critical condition of penetrating into the target using numerical simulation method. Next, we determined the optimal combination of different factors at various levels using orthogonal optimization design with consideration of safety margin in practical application and the interaction between two different parameters. At last, we conducted a field test to validate the correctness of both numerical simulation and the optimal combination. The results indicated that the orthogonal optimization method and the simulation results agreed fully with the physical principal.
