摘要
为了确定输出条件下燃气做功元件装药参数,用VLW状态方程计算了点火药和主装药的火药力、余容,结合诺贝尔-阿贝尔方程,对不同输出特性做功元件的装药参数进行了设计,容积为1cm3的做功原件压力输出试验结果表明:点火药(B／KNO3)为0.2g、主装药(RDX)为0.0995g时,做功元件输出最大压力平均值为179MPa,与设计值192MPa接近;点火药(B／KNO3)为0.2g、主装药(RDX)为0.199g时,做功元件输出最大压力平均值为348MPa,与设计值384MPa接近。
To determine the charge parameters of combustion pots in various conditions, VLW EOS method is used to calculate co-volume and impetus of ignition charges and explosive charges. The calculated results together with Nobel-Abel EOS, are used to predict charge parameters of combustion pots for attaining some maximum pressure output. Experiments with 1 cm3 combustion pot indicate that the average maximum pressure output of combustion pots with 0. 2 g B/KNO3 (ignition charge) and 0. 0995 g RDX (combustion charge) is 179 MPa, and that of combustion pots with 0.2 g B/KNO3 and 0.199 g RDX is 348 MPa,respectively close to 192 MPa and 384 MPa which are design values by VLW EOS method.
