射流撞击下发射装药的易损性响应特性

Vulnerability Response of Propellant Charges under Shaped Charge Jet Impact

用空心装药射流作标准射流源,研究了4种典型发射装药在空心装药射流撞击下的易损性响应特性。分析了约束条件、尺度效应等对响应结果的影响。结果表明,4种典型发射装药均发生了较为强烈的反应,由弱到强的排序为太根药、单基药、硝基胍药和硝胺药,其反应等级依次为爆炸、爆炸、部分爆轰和部分爆轰。

The vulnerability response characteristics of the four typical propellant charges under shaped charge jet impact were studied using shaped charge jet as standard jet source. The effects of the restrict condition and scale effect on the response results were analyzed. The results show that the reaction of the four typical propellant charges take place intensively,the order of vulnerability response from feeble to strong is as follows：TEGN propellant〈single-base propellant〈nitro-guanidine propellant〈nitramine propellant. Their reaction rating is explosive, explosive, part explode and part explode, respectively.
