It has been established both theoretically and experimentally that the penetration of a well developed jet produced by a hollow charge can be regarded as a quasi-steady state process. Under such circumstances, the penetration process can be characterized by the relation between jet velocity u_j and penetration velocity u.This paper examines u_j-u relation as well as the penetration of a jet, part of which has broken up into pieces. Five problems are discussed:1) on an empirical u_j-u relation;2) superposition...

It has been established both theoretically and experimentally that the penetration of a well developed jet produced by a hollow charge can be regarded as a quasi-steady state process. Under such circumstances, the penetration process can be characterized by the relation between jet velocity u_j and penetration velocity u.This paper examines u_j-u relation as well as the penetration of a jet, part of which has broken up into pieces. Five problems are discussed:1) on an empirical u_j-u relation;2) superposition of the depth of penetration and time relations;3) a proposal to determine u_j-u relation experimentally;4) on the thickness of the "hydrodynamic" zone;5) penetration of a broken up jet.

这篇报告以射流速度与侵彻速度的关系(简称u_j-U关系)和拉断后射流的侵彻为中心,讨论射流侵彻中互相有联系的几个问题。报告分为以下几个部分: 一、u_j-u的经验关系; 二、穿深、时间关系的叠加; 三、关于u_j-u关系试验测定的一个建议; 四、关于“流体区”的厚度; 五、拉断后射流的侵彻。

Hollow projectile is virtually a thin-walled tube, also known as tube projectile. It is characterized by its light weight, high muzzle velocity and desired aerodynamic behaviour. Hence it provides the advantages of lower impulse, straighter trajectory, smaller dispersion and excellent penetrating power.

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。

A tank is taken as a revolving hollow ellipsoid. Equations for the calculation of magnetic field are derived, based on a special coordinate system established around that ellipsoid. A numerical example is finally given to illustrate the method.

本文将坦克近似为一个空心的旋转椭球体,应用旋转椭球坐标系,推导出坦克磁场的计算式,并举例计算了坦克的磁场,对了解坦克磁场有参考价值。
