| Abstract: | In this paper, based on incompresible fluid model, the jet formation theory oi' linear shaped cumulative charge cutter under glancing detonation is investigated. The jet. velocity, the condition to be satisfied for piercing fluid-model and the effect of spraying jet on cutting results are discussed. The best opening angle of cutter hood when the jet energy in vertical direction is maximal is ascertained too. |
