【摘要】 研究了吸收与未吸收硝化甘油（ＮＧ）这两种包覆单基发射药在老化过程中力学性能与界面粘接强度的变化规律，实验结果表明，吸收了ＮＧ的单基药能明显改善其界面粘接强度，在不同温度条件下老化后都不脱粘，符合低温度系数发射药的技术要求并取得最佳弹道效果。更多还原

【Abstract】 S The dependance of mechanical properties on interfacial bonding strength of two kinds of coated single base propellants during their aging process was studied. It is concluded that the interfacial bonding strength of coated single propellant can effectively be improved by absorbing nitroglycerin(NG) and makes it non debonding after aging under different temperature,which agrees with the requirements of low temperature coefficient propellants to reach the optimum ballistic effect.更多还原
