摘要
通过中止燃烧试验及密闭爆发器试验研究了含FOX-7发射药的低压燃烧性能。结果表明:随着样品中FOX-7含量的增加,其燃速压力指数降低;发射药燃烧过程中,药体表面形成连续的熔融层,抑制了RDX的爆燃,发射药燃烧一致性变好,有利于发射药低压下的稳定燃烧。抗冲强度试验结果表明,增加配方中FOX-7含量,发射药抗冲强度增大。
The combustion performance of gun propellants containing FOX-7 at low pressure was studied by quenched burning tests and closed bomb tests. Results show that the pressure exponent reduces with increasing of the content of FOX-7 in propellant,and consecutive melted layer on propellants surface formes during combustion process. It restrains the deflagration of RDX,and the combustion consistency of propellant better,which is helpful for the stable combustion of propellant at low pressure. Impact test results indicate that with the increasing of FOX-7 content in formula,impact strength of propellants improves significantly.
