端羟基聚叠氮缩水甘油醚与六硝基六氮杂异伍兹烷基四元混合炸药能量释放研究

为研究六硝基六氮杂异伍兹烷(CL-20)的能量潜力，结合含能粘合剂端羟基聚叠氮缩水甘油醚(GAP)，计算了GAP、CL-20、氧化剂、可燃剂四元混合炸药的爆炸能量。计算结果表明，使用高氯酸锂作氧化剂可显著提高体系的能量密度，但将其在浇注混合炸药中得到应用需要进一步改性研究。制备了GAP、CL-20、高氯酸铵、铝粉四元混合炸药样品，利用水下爆炸测试方法，测试并估算了其水下爆炸能量。试验结果表明：在该四元体系中，CL-20含量为15%~20%时，体系能量密度可得到最大值；在CL-20含量为20%条件下，铝氧比为0.50时冲击波能可取得最大值，铝氧比为0.51~0.71时CL-20混合炸药能量密度可达到最大，通过水下爆炸试验数据估算其能量密度可达到2.88倍TNT当量。

Study of the Energy Release of CL-20/GAP-based Quaternary Explosive

CL-20 is one kind of high energy explosive with wide application prospect. The explosion energy of GAP/CL-20/oxidant/combustible agent quaternary system explosive is calculated to study its potential energy. The calculated results show that lithium perchlorate can be used significantly to improve the explosion heat, but the use of it in the cast explosive needs the further research on its modification. The samples of GAP/CL-20/AP/Al explosive were prepared, and the test method of underwater explosion was used to test and estimate its underwater explosion energy. The test results show that the energy density of the quaternary explosive can achieve the maximun with a CL-20 content of 15-20 wt%, and the explosion heat of CL-20 based GAP cast explosive can achieve the maximum when the Al/O is between 0.51-0.71 with a CL-20 content of 20wt%. According to the test data, the estimated energy density of the explosive can be up to 2.88 times of TNT equivalent.
