设计了一种长径比为 0 .375 ,罩锥角为 12 0°的大锥角小长径比聚能装药。利用闪光X射线摄影技术观察了小长径比聚能装药正向起爆时形成的射流图象以及逆向起爆时药型罩的压垮图象和射流图象。给出了形成射流的头部速度、射流的质量分布等射流特性参数。试验的聚能装药逆向起爆时射流头部速度为 7.48km/s,而正向起爆时仅为 4.34km/s。试验研究表明通过逆向环形起爆 ,小长径比聚能装药获得高速射流是可行的
A long-diameter ratio of 0. 375, a large taper angle of 12 0 ° with a large taper angle and a smaller length-diameter ratio was designed. The jet image formed by the positive protuberance with small aspect ratio and the protuberant protuberance and the jet image were observed by flash X-ray photography. The jet velocity parameters, such as the head velocity and jet mass distribution, are given. Experimental reverse charge of charged charge jet head speed of 7.48km / s, and only 4.34km / s forward detonation. Experimental studies have shown that it is feasible to obtain a high-velocity jet by convergent charge with a small aspect ratio through reverse toroidal initiation
