| 摘 要： | 为了解双层变燃速发射药的热膨胀性能规律,采用膨胀系数测定仪测定了一种类双基型中心开孔双层变燃速发射药的线膨胀系数,结果表明,外层药的线膨胀系数大于内层药的线膨胀系数.推导了变燃速药型的轴向线膨胀系数与内、外层药的线膨胀系数以及几何尺寸之间的理论关系式,并计算了变燃速发射药的线膨胀系数,与实测值的相对误差小于10%. |
| 关 键 词： | 材料科学 变燃速发射药 线膨胀系数 几何尺寸 热膨胀 |

| Abstract: | In order to understand the thermal expansion behavior rule of two-layer variable burning-rate gun propellant,the linear expansion coefficients were measured by use of an expansion coefficient determinator for a kind of variable burning-rate gun propellant samples which are analogous to double-base gun propellant and have a central hole and two layers.The results show that the linear expansion coefficient of outer layer is larger than that of inner layer.Aiming to this shape of variable burning-rate gun prop... |
