Protection of armoured vehicles against chemical,biological and radiological contamination

The article presents problems related to mechanical protection of vehicles with different add-on armours against chemical,biological and radiological contamination.This applies to vehicles with additional passive,reactive and hybrid protection in the form of cassettes against piercing with anti-tank pro-jectiles,piercing with their kinetic energy of impact,and as a result of chemical energy of shaped charges as well as explosively formed projectiles.It has been shown how increased ballistic protection of these vehicles at the same time reduces their decontaminability in various places of the vehicle due to the increased additional surface of the vehicle with cassettes.Prevention of contamination of these cassettes has been presented as a way of reducing hard to reach surface for decontamination and a method of insulating construction elements(stands),fixing these cassettes to the vehicle,from the environment to prevent contact with contaminated liquids and dusts.The selection of appropriate materials is shown,which may affect the improvement of the decontamination efficiency of the vehicle with such cassettes.This applies to the use of materials with low absorption of chemical warfare agents,which prevent the accumulation of large amounts of these agents on contaminated surfaces and improve the effectiveness of decontamination.It also shows how to ensure better access of the disinfectant to as much of the vehicle surface as possible,covered with cassettes that have been contaminated.It shows how a vehicle,in particular with such cassettes,can provide protection against radar detection when Radar Absorbent Material is used on vehicle cassettes.     

一种攻击机机群作战效能的分析方法

以平均动态学理论为基础,提出了攻击机机群在整个战斗飞行过程中的作战效能评估的基本原理,建立了战效评估的顶层分析数学模型,导出了效能指标与对地攻击靶场效能指标、国土防空系统突防效能指标、要地防空系统突防效能指标间的关系式及完成作战任务集所需飞机架数、被击毁的总架数、总战斗飞行架次数、武器总消耗量的计算式,为评价攻击机机群在整个战斗飞行过程中的作战效能奠定理论基础     

机群对地攻击分析动力学模型的建立及仿真分析

根据兰彻斯特作战动态方程的研究方法建立了机群对地攻击效果的分析动力学模型,并通过仿真分析、讨论了影响对地攻击效果的可能因素,如:目标分配形式,目标发现概率,攻击结果侦察概率以及假目标等.     

地面防空作战信息对抗模型研究及仿真

在地面防空作战中,地空导弹和空中目标的对抗是一个动态的对抗过程。通过把模型分为自身状态和对对方的估计状态,建立了防空作战对抗模型,分析了导弹追击和目标逃避时的控制输入的选择原则。通过仿真,得到了较好的结论,体现了导弹和目标之间的对抗性,对进一步研究地面防空系统对抗性建模方法具有重要意义。     

基于多子网语言决策图的空管体系绩效评估

为评估空管体系综合绩效水平,制定了关键绩效领域和指标,提出基于多子网语言决策图的群体评估模型。采用多子网策略分析领域及指标间的影响关系,应用语言尺度辅助群体专家建立了领域及指标间的初始判断矩阵和影响连接矩阵。给出了模型的求解方法,在求得各子网内准则的全局权重后,聚合即可得到体系的综合评估值。案例分析表明,相比于不考虑领域及指标间影响的情况,模型结果能更客观、全面地展示各领域及指标的权重,更显著地揭示空管体系间的差距。     

防空导弹反临近空间武器作战能力评估

针对防空导弹反临近空间武器作战能力的问题,建立了多级综合评价指标体系。结合三角模糊数的层次分析法和信息熵法对各二级指标进行综合赋权,同时,运用灰色关联度TOPSIS的组合评估法,构造了一种组合贴近度,据此评价防空导弹作战能力的优劣性。通过算例分析,对各型防空导弹作战能力进行优劣排序,验证了该组合评估模型的可行性,实现了对防空导弹反临近空间武器作战能力的综合评估。     

From one exceptionalism to another: France’s strategic relations with the United States and the United Kingdom in the post-Cold War era

ABSTRACT

The failed expedition of Suez in 1956 and France’s subsequent strategic ‘divorce’ from the United Kingdom and the United States lies at the heart of a policy paradigm that has dictated France’s defence posture from de Gaulle’s presidency to the end of the Cold War. Some crucial features of the Gaullist posture remain today enduring references for French presidents in the definition of France’s exceptionalism. While it is so, there have been significant changes since the 1990s when it comes to France’s strategic relations with the United States and the United Kingdom. This article demonstrates the extent and mechanisms of this rapprochement by analysing it through three dimensions of policy change: modes of action, institutional commitments and discourses. The article demonstrates the dimensions’ mutually reinforcing effects and argues that France’s exceptional posture has de facto been reversed.     

The African Standby Force: The African Union’s tool for the maintenance of peace and security

Declared operationally ready in 2016, the African Standby Force (ASF) has not been deployed in its originally designed form. This is not for the lack of opportunities but rather a demonstration of the power of the Regional Economic Communities/Regional Mechanisms (RECs/RMs) – Africa’s sub-regional security structures – over matters of peace and security. Experience gathered from its short existence suggests that the ASF may never be deployed in its current form. It may instead evolve into a robust framework, adaptable mainly by the RECs/RMs, for addressing varied security challenges. Four things are critical to enhancing the utility of the ASF: the political willingness of the RECs/RMs, the strategic interest of the member states, predictable and sustainable financing, and clarity on the role of the African Capability for Immediate Response to Crisis, the temporary battlegroup that was created to provide the African Union with a rapid response capability, pending the ASF’s operationalization.
