摘要:
为了研究单基发射药对意外剧烈热刺激的响应特性，开展了单芳-X（DF-X）与单芳-Y(DF-Y)两种发射药的快速烤燃、约束强度对快速烤燃响应特性影响的相关试验。结果表明，相同约束强度下，DF-X的快速烤燃响应等级为爆燃，比DF-Y的快速烤燃响应等级更高。与DF-Y相比，DF-X粒度小、比表面积大、装药密度高、孔隙率低、导热效率高。因此，DF-X的反应燃速更快，响应等级更高。壳体约束强度对两种单芳类发射药快速烤燃响应程度均有显著影响。随着约束壳体厚度从2 mm增加到3 mm，DF-X与DF-Y的快速烤燃响应等级未发生阶跃改变；但是，随着壳体约束强度的增加，烤燃弹试件内部的环境压力变大，导致发射药燃速加快，快速烤燃响应剧烈程度更高。
Abstract:
In order to study the response characteristics of single-base propellants to accidental severe thermal stimulation, fast cook-off tests of single-aromatic-X (DF-X) propellant and single-aromatic-Y (DF-Y) propellant were conducted, and the influence of constraint strength on their response characteristics during fast cook-off tests were also studied. The results show that under the same constraint intensities, the fast cook-off response level of DF-X is deflagration, which is higher than that of DF-Y. Compared with DF-Y, DF-X has the characteristics of smaller particle size, larger specific surface area, higher charge density, lower porosity and higher thermal conductivity. Therefore, DF-X has a faster reaction burning rate and higher response level. The constraint intensity of the shell has a significant impact on the fast cook-off response of the two single-aromatic propellants. As the thickness of the confining shell increases from 2 mm to 3 mm, the fast cook-off response levels of DF-X and DF-Y remain unchanged. However, with the enhancement of constraint intensity, the internal environmental pressure of the cook-off test specimen elevates, resulting in an accelerated burning rate of the propellant and a higher degree of fast cook-off response.
