低易损推进剂机械刺激下的试验、机理、配方的研究进展

Research Progresses of Experiment, Mechanism, and Formulas of Low Vulnerable Propellants under Mechanical Stimulations

基于我国的低易损推进剂试验和理论研究工作相比于国外起步较晚,尤其是子弹冲击、破片冲击、聚能射流冲击等机械刺激作用下的低易损研究,受到试验条件和评估标准的限制更为严重,研究的滞后性尤为突出。为了给后续研究工作提供一些帮助,总结了三个方面的研究进展。一是低易损推进剂子弹冲击、破片冲击、聚能射流冲击的试验结果;二是低易损推进剂在机械刺激下的响应机理;三是低易损推进剂的配方研究工作。最后提出了几点建议,希望对国内的相关理论研究和生产实践有所帮助。

The theoretical and experimental researches of low vulnerable propellants in China are hysteretic compared with other countries,especially in the fields of bullet impact,fragment impact,and shaped charge jet impact,because they are limited by experimental conditions and assessment standard.To provide assistants for subsequent researches,progresses in three aspects were summarized in this review,including the experimental results of bullet impact,fragment impact,and shaped charge jet impact,the response mechanism of low vulnerable propellants suffering mechanical stimulations,and formulas researches of low vulnerable propellants.Some advices were provided finally to help the theoretic researches and industry productions in China.
