Research on the Discarding Characteristic of a Novel Sabot
-
摘要: 为避免脱壳穿甲弹出炮管后与炮口制退器的相互干扰，在传统“马鞍形”弹托的基础上研究了一种新型结构弹托。分析了这种弹托的脱壳机理，并对该弹托进行了脱壳试验。研究结果表明，通过调整迎风面倾斜角度、减小迎风槽和背风槽的体积大小、在前定心部开设均匀分布的圆柱形通孔，可以减小弹托的分离角度，避免了弹托与制退器的相互干扰。Abstract: In order to avert the mutual interference that occurs between the armor piercing discarding sabot and the muzzle brake when the armor piercing projectile ejects out of the gun barrel, a novel sabot was designed based on the traditional saddle-shaped sabot.The discarding mechanism of the novel sabot was analyzed, and the discarding experiments of the sabots were carried out.The results show that by adopting a series of measures such as adjusting the tilt angle of the windward side, reducing the volume of the windward and the leeward troughs, distributing uniformly the opened cylindrical holes in the sabot's leading edge, the discarding angle of the sabot can be reduced, thereby averting the mutual interference between the armor piercing discarding sabot and the muzzle brake.
