脱壳穿甲弹弹托风洞测压试验及气动力特性

介绍了脱壳穿甲弹在弹托后定心部离开炮膛瞬间，弹托与弹有仍处在包紧（弹托与弹芯之间没有气体流过）状态下进行的脱壳穿甲弹弹芯与弹托组合体的风洞测压实验，文中给出通过所有测压点的分布曲线，在此基础上，通过对单瓣弹托轴对称和非轴对称部分的气动力计算，分析了单瓣弹托的受力及其气动力特性。上述所得结果为脱壳机理的研究提供了一定的依据。

Wind Tunnel Test of Measuring Pressure and Aerodynamics Characteristic on the Sabot of Armor Piercing Discarding Sabot

This paper introduces the situation of wind tunnel test of measuring pressure on the body composed of the core and the sabot of armor piercing discarding sabot (APDS),which tightly holded at the mpment the back centering section of APDS departing from the bore of a gun (no gas flows between the core and sabot). The testing and theoretically calculating pressure results are given in the paper- A pressure distribution curve through all measuring pressure points is completely obtained- According to this, the aerodynamics and aerodynamic characteristics of a single sabot are analysed through aerodynamic calculation of axial symmetric part and axial unsymmatric part on a single sabot. The resu1ts provide some criteria for researching discarding sabot mechanism.
