摘　　要：利用二级轻气炮，进行了980～1870m／s速度范围内小尺寸弹体非正侵彻半无限混凝土靶实验，详细测绘了弹道轨迹及特征参数，重点研究了高速非正侵彻的弹道特性，并根据侵彻机理进行了侵彻过程分区。研究结果表明：与中、低速条件下的弹道不同，高速弹体非正侵彻半无限混凝土靶的侵彻弹道偏转更为明显，表现为典型的“J”形弹道，弹体终点姿态变化很大，弹道末端的偏转角可达130°。The experiments of small scale projectile obliquely penetrating a semi-infinite concrete target with a velocity from 980 to 1 870 m/s are performed by a two-stage light gas gun. The ballistic trajec- tory and characteristic parameters are tested and painted. The results show that the trajectory deflec- tion of the penetrator obliquely penetrating a semi-infinite concrete target with high velocity is more obvious than that with intermediate and low velocities,and presents a shape of ＂J＂. The penetration process can be divided into four phases according to the penetration mechanism. In addition,it is found that the terminal gesture of the projectile changes greatly, and the deflection angle at endpoint can reach up to 130°.
