空心弹丸基本上是一个中空薄壁圆管(因而又称管式弹丸),它的重量轻、初速高、气动性能好,从而使得膛口冲量小、弹道低伸、散布小,并且具有优越的侵彻效果。本文在前人研究成果的基础上,结合我们的试验研究情况,比较详细地叙述了这一新弹种的低阻性能、散布精度和侵彻性能;从理论上分析对比了空心弹丸和实心弹丸的陀螺稳定性;给出了空心弹丸的阻力特性近似估算方法;最后,就这一新弹种在弹药上应用的可能性问题提出了一些看法和建议。 The hollow projectile is basically a hollow thin-walled circular pipe (henceforth called a tubular projectile). Its light weight, high initial speed and good aerodynamic performance make the bore impulse small, ballistic low, scattered small, and has excellent penetration effect. Based on the previous research results, this paper describes the low resistivity, spreading accuracy and penetration performance of this new species in combination with our experimental research. The theoretical analysis and comparison between hollow projectile and solid projectile Gyro stability of hollow projectile. The method to approximate the drag characteristic of hollow projectile is given. Finally, some opinions and suggestions are put forward on the possibility of applying the new projectile to ammunition.
