Defence industry in Iran – between needs and real capabilities

ABSTRACT

The paper’s goal is to analyses the potential of the Iranian defence industry, including both research-and-development and production capabilities. It is argued that, despite official statements about the great power and sophistication of the Iranian defence industry, in reality its capabilities are very limited and cannot meet the operational needs of the Iranian armed forces. At the same time, it is argued that many official releases, which are abundantly available in the Iranian press and often unthinkingly repeated by the Western media, do not present the real and value of military products, but are rather a tool for deception and propaganda.     

R技术在防空武器系统研制生产中的应用

虚拟现实 (VirtualReality ,简称VR)技术是当今世界前沿科学之一 ,更是一个充满活力和挑战的研究领域。国外经济发达国家一直将其列为国防高科技重点发展的关键技术 ,迄今已成为开发研制、生产大型而复杂的防空武器系统的重要工具。扼要介绍其在防空武器系统研制、生产中的应用。     

弹道导弹突防方案与拦截策略的对抗研究

Building Stability Overseas: Three case studies in British defence diplomacy – Uganda,Rhodesia–Zimbabwe,and Sierra Leone

In 2011, the Department for International Development, the Foreign & Commonwealth Office, and the Ministry of Defence launched the Building Stability Overseas Strategy (BSOS). This document sought to integrate cross-government activity as it related to conflict and security so as to ‘take fast, appropriate and effective action to prevent a crisis or stop it escalating and spreading’. At the heart of the strategy was the recognition that addressing instability and conflict overseas was morally right and in the UK's national interests. This confluence of foreign policy realism and ethical outlook most clearly found harmony in the acknowledgement that it was cheaper for the international community to avoid conflict than it was to try to manage it. Through an examination of three historical case studies (Uganda 1964–1972, Rhodesia–Zimbabwe 1979–1981, and Sierra Leone 2000–2007), this article seeks to demonstrate just how difficult this seemingly sensible strategic outlook is. In particular, the article shows there are historical parallels in British postcolonial history that very closely resemble contemporary policy choices; that these can be used to define what is different about past and present practice; and, which in turn, can be used to – at least tentatively – mark out the potential strengths and weaknesses in BSOS.     

压电-正交基体复合半圆柱的界面端部开裂问题研究

建立了半圆柱形压电-正交基体复合材料界面端部开裂问题的力学模型,其中压电层为锆钛酸铅铁电陶瓷,基体为正交异性聚乙烯复合材料。综合利用位错模拟法、格林函数法和奇异积分方程法,对裂纹问题进行了理论分析。通过对应力强度因子进行数值求解和讨论,揭示了几何、物理参数对断裂行为的影响规律。从界面端部止裂的角度出发,找到了压电复合半圆柱的2种优化设计形式:一种是将"较软的内部基体"和"较硬的外部压电层"相结合;另一种是采用正交各向异性介电材料作为基体。另外,数值计算还表明:与剪切模量变化对应力强度因子的影响相比,压电系数和介电系数变化的影响至少要小2个数量级,因此后面二者对结构防断裂优化设计没有显著的实际意义。

The subversion of the Bulgarian defence system – the Russian way

Russia has long been pursuing an intended and calculated policy of keeping enough influence in Bulgaria in order to have control over national decisions. Together with the economic, energy, political and information tools used by Russia in its hybrid war against Bulgaria and in its bid to achieve an enduring “state capture,” defence is also a distinct target of Russian subversion now. A list of noticeable subversive actions with tangible effects can be summarised, ranging from fuelling division and manipulating public opinion, preventing the strengthening of the NATO position in the Black Sea, sabotaging defence reform to various options of subverting the modernisation of the Bulgarian Armed Forces and seeking new ways to keep legacy Soviet military equipment in operation as long as possible. This issue must be urgently addressed both nationally and in NATO.
