Think again – supplying war: reappraising military logistics and its centrality to strategy and war

This article argues that logistics constrains strategic opportunity while itself being heavily circumscribed by strategic and operational planning. With the academic literature all but ignoring the centrality of logistics to strategy and war, this article argues for a reappraisal of the critical role of military logistics, and posits that the study and conduct of war and strategy are incomplete at best or false at worst when they ignore this crucial component of the art of war. The article conceptualises the logistics–strategy nexus in a novel way, explores its contemporary manifestation in an age of uncertainty, and applies it to a detailed case study of UK operations in Iraq and Afghanistan since 2001.

极化域-空域联合估计在反辐射导弹抗诱偏中的应用研究

提出了将极化阵列应用到反辐射导引头上,导引头利用目标与诱饵的极化差异,采用极化域-空域联合估计方法抗诱偏。首先,利用波达方向矩阵法,估算出雷达与诱饵的空间二维到达角和极化参数,将估算出来的二维到达角信息为反辐射导引头提供导引,极化参数用来鉴别雷达与诱饵,从而达到抗诱偏的目的。然后,结合导弹运动方程及导引方程对反辐射导弹抗三点源诱偏进行了全弹道数字仿真,并且采用Monte-Carlo方法对全弹道仿真进行了多次实验,仿真结果证明了将极化域-空域联合估计应用于反辐射导引头抗诱偏的可行性。     

North European security after the Ukraine conflict†

Russia’s illegal occupation and annexation of the Crimean peninsula in February–March 2014, and the country’s well-documented involvement in the separatist conflict in Eastern Ukraine, have led to a significant worsening of Russia’s relations with the West. Vladimir Putin’s move to redraw Russia’s southern borders through the use of military force and subversive measures has given rise to an uncertainty that goes well beyond the post-Soviet space. Since 2014, North Atlantic Treaty Organization (NATO) has had to reassess many aspects of its relationship with Russia. The alliance has also initiated various measures to strengthen the military security of its eastern member states, particularly the Baltic states, Poland, and Romania. Further to the North, NATO’s northernmost member – Norway – is following developments in Russia with a heightened sense of awareness. The same goes for non-aligned Sweden and Finland, which are trying to adapt to the emerging, and increasingly complex, security environment in Northern Europe.     

二次流引射对保形非对称喷管性能的影响

发动机与飞机后体结构设计合理与否直接影响发动机的部件匹配和性能。利用三维雷诺平均N-S方程和k-ωSST湍流模型对飞翼布局无人机保形非对称喷管在典型飞行状态下开展了内外流流场特性的数值分析,获得了后体尾喷管推力性能和三维流动特征随二次流压力比的变化趋势。结果表明:发动机喷管落压比条件一定的前提下,通过合理优化二次流通道、增大二次流压力比,可以有效改善后体/喷管主流流场特性;当二次流与主流的流量比在0. 2%～1. 86%内时,后体尾喷管轴向推力系数的变化幅度大约为3%,在一定程度上能够减弱发动机主流的过膨胀程度,减小发动机推力损失,无人机后体尾喷管性能得到显著提高。     

化学毒剂及相关化合物的色谱及质谱分析检测研究进展

介绍了当前对毒剂及相关化合物的色谱及质谱分析检测研究进展和发展趋势。仪器设备方面,气相色谱-质谱联用仪仍是主力仪器：但对热不稳定性及难挥发性化合物来说,用液相色谱-质谱来分析则更为合适;发展现场可用的、便携式鉴别技术和设备也是一个发展趋势。分析化合物方面,不能局限于附表化学品,应该积极开展对毒素及毒物与生物体加合物等复杂化合物的分析研究。样品基质方面,应该展开对新型消毒剂样品及生物样品的研究。     

大口径舰炮将重展雄风

由于浅水战争和不对称威胁,要求在中短距离上攻击各种目标,但这种条件常常严重地阻碍了反舰导弹性能的发挥。同反舰导弹相比,大口径火炮要便宜得多,能更加即时地使用,且快速灵活,所以现在各大军事强国都在加紧研制新型大口径舰炮,重新考虑使用大口径火炮来代替反舰导弹,并且提供海上火力支援,使大口径舰炮重新登上战舰的舞台。为此,介绍了美国、德国、英国、意大利、俄罗斯、法国的大口径火炮研制情况。
