The elliptical cross-section ogive-nose projectile (ECOP) has recently attracted attention because it is well suited to the flattened shape of earth-penetrating weapons. However, the penetration performance of ECOPs has not been completely understood. The objective of this study was to investigate the pene-tration performance of ECOPs into concrete targets using a theoretical method. A general geometric model of ECOPs was introduced, and closed-form penetration equations were derived according to the dynamic cavity-expansion theory. The model was validated by comparing the predicted penetration depths with test data, and the maximum deviation was 15.8%. The increment in the penetration depth of the ECOP was evaluated using the proposed model, and the effect of the major—minor axis ratio on the increment was examined. Additionally, the mechanism of the penetration-depth increment was inves-tigated with respect to the caliber radius head, axial stress, and resistance. 相似文献

ABSTRACT At the turn of the nineteenth century, China’s Qing dynasty (1644–1912) was hit by a sectarian rebellion. Commonly considered a breakpoint marking the end of the dynasty’s golden age spanning most of the eighteenth century, the war to suppress the rebels, referred to as the White Lotus War (1796–1804) in this article (‘White Lotus’ was the umbrella name used by both the authorities and some sectarians for their teaching), exposed many structural drawbacks of the Qing political and military systems and depleted the dynasty’s financial resources, which had never been recovered. Reluctant in embracing guerrilla warfare in the beginning, the insurgents quickly turned themselves into master guerrillas. Shuttling in two massive mountain ranges in central China, they managed to prolong their rebellion and fought some successful battles against their suppressors. Superior in manpower, weaponry, and logistical support, the government forces had to adapt to guerrilla warfare, albeit passively and ineptly. This article gives a brief introduction to this little-known episode of guerrilla war at the turn of the nineteenth century in Qing China, expounds the strengths and weaknesses of both sides, and sheds light on the roots of the war’s long duration and the grim consequences to the Qing state. 相似文献

为评估国防科技投资的区域经济效应,本文基于投入产出模型,运用湖南省2002年投入产出表中的相关数据进行实证分析,结果表明国防科技部门对国防科技投资分布密集的地区存在着重要影响。但国防科技部门的产业波及效应较小,说明需要进一步畅通军民融合渠道,以充分发挥国防科技对地区经济的影响。 相似文献

非战争军事行动中政治工作具有双重性特征,既要保证艰巨性任务的完成,更要保证政治性方向的贯彻;既要对内激励官兵,凝聚力量,更要对外宣传群众,稳定社会;既要保证部队指挥有力,更要保证军地协调到位。积极适应、正确把握非战争军事行动及其政治工作的双重性特征,对于提高政治工作的效率和效果具有重大意义。 相似文献

针对装甲装备传动装置旋转体密封部位经常发生漏油的现象,在分析现有密封环失效机理的基础上设计出一种新式密封环——搭接式弹性密封环,并对其结构特点、工作原理等进行了理论分析。经台架空载和实车使用试验表明:不仅使漏油问题得到彻底地解决,而且有效地提高了修理质量,维修工效也得到明显提高。 相似文献
