The Numerical Simulation on Jet Formation of Double-layered Conical Liner Forming F-charge

In order to study the formation of jet from double-layered conical liner (DLCL) forming F-charge, the LS-DYNA program was used for simulating the formation process of the DLCL forming F-charge. The effect of different materials of outside layer and different space between the layers on characteristics of the jet from DLCL were discussed. The result shows that the material used as the outside layer and the space between the double layers have an influence to the characteristic of the jet from DLCL forming F-charge. Reasonably adjusting the outside cover's material and the space between the layers can help to improve the performance of the jet.
