本文介绍利用点起爆原理试制成功一种新型无枪身聚能射孔弹。这种射孔弹的总炸药量为13.7克,平均穿透钢锭80毫米以上,孔径8—10毫米,射孔不破坏套管,这对提高射孔弹质量是个突破。 In this paper, a new type of gun-free shaped projectile is successfully trial-produced by using the principle of point detonation. The total explosive charge of this type of projectile was 13.7 grams, with an average penetration of 80 mm or more in the ingot and a diameter of 8-10 mm. The perforation did not destroy the casing, which was a breakthrough in improving the quality of the perforation charge.
