机动发射条件下助推滑翔导弹射击诸元快速解算

针对机动发射条件下助推滑翔导弹对全程弹道快速生成的迫切需求,在弹道设计中选取7个关键性控制量参数作为全程弹道射击诸元,并提出与之相对应的诸元解算算法。将全程弹道分为助推段、初始下降段、滑翔段和俯冲攻击段,在统一化运动模型描述的基础上,运用参数化迭代的思路,依次对不同飞行阶段诸元进行了快速求解,满足多种复杂约束条件。在全程诸元迭代解算模式的基础上,提出助推段沿用中心弹道诸元,仅对其他射击诸元进行重计算的部分诸元迭代解算模式。仿真结果表明:采用所提助推滑翔导弹射击诸元快速解算方法,可在大范围机动条件下对远距离地面固定目标进行快速精确打击。     

弹炮结合防空武器系统机动生存能力模型研究

从弹炮结合防空武器系统通过机动作战提高生存能力的角度出发,结合防空武器系统机动作战过程中的战术背景,提取了该过程中决定防空武器系统生存能力的决定性要素,然后分析了该过程中影响防空武器系统生存能力的总机动时间、被发现概率、抗击成功率、被毁伤概率等各项指标的特点,在此基础上建立了用于研究该过程的数学模型,最后给出实例进行了仿真计算,通过对计算结果的分析,证明了该模型的有效性,从而为防空兵机动作战模拟提供了一定的参考.     

浮筏隔振系统隔振器最佳布置方案研究

浮筏系统已经大量应用到舰船动力装置和其它设备的减振降噪中.运用导纳原理推导了双层减振装置隔振器对齐安装和不对齐安装方案的传递功率流,发现由于结构传递导纳小于输入导纳,不对齐安装更有利于降低宽频率振动的传递,并用有限元分析法实例验证了结论,为浮筏的优化设计和优化布置奠定了理论基础.

Decision support model for effects estimation and proportionality assessment for targeting in cyber operations

Cyber operations are relatively a new phenomenon of the last two decades.During that period,they have increased in number,complexity,and agility,while their design and development have been processes well kept under secrecy.As a consequence,limited data(sets)regarding these incidents are available.Although various academic and practitioner public communities addressed some of the key points and dilemmas that surround cyber operations(such as attack,target identification and selection,and collateral damage),still methodologies and models are needed in order to plan,execute,and assess them in a responsibly and legally compliant way.Based on these facts,it is the aim of this article to propose a model that i))estimates and classifies the effects of cyber operations,and ii)assesses proportionality in order to support targeting decisions in cyber operations.In order to do that,a multi-layered fuzzy model was designed and implemented by analysing real and virtual realistic cyber operations combined with interviews and focus groups with technical-military experts.The proposed model was evaluated on two cyber operations use cases in a focus group with four technical-military experts.Both the design and the results of the evaluation are revealed in this article.

From combat to non-combat action

This paper examines the rationale and centrality of private military and security companies (PMSCs) in humanitarian assistance operations in Sudan, asking why PMSCs are involved in humanitarian assistance operations in Sudan and what the principles underlying their activities are. To answer this question, the paper draws attention to the link between humanitarian crises and PMSC interventions. Where there is no meaningful alternative intervention, undergirded by humanitarian concerns that are also profit driven, PMSCs come in to provide the needed services. The protracted and complicated internal armed conflicts in Sudan, which have lasted for over two decades, have produced as many as 4,8 million internally displaced persons (IDPs) – the single largest number in the world. The kind of humanitarian assistance operations provided by PMSCs in Sudan have become critical to the provision of much-needed services which were inadequately provided by governmental authorities at both unilateral and multilateral levels. This paper argues that the humanitarian crises in Sudan created a regime that permits humanitarian assistance operations by both state and non-state actors.     

The long and winding road … to success? Unit peace operation effectiveness and its effect on mission success

Why does peacekeeping sometimes fail? How can effective peacekeepers increase the likelihood of success of a mission? The two main flaws in the current evaluations of peace operations are that they mainly rely on already concluded missions and that they make use of indicators that do not reveal micro-level dynamics. This article introduces an analytical framework relating the effectiveness of soldiers to their actual impact in their area of operation in a peace operation. The framework is called “unit peace operation effectiveness” (UPOE). Focusing on soldiers in peace operations, this article shows that: different units behave differently; emphasize different aspects of the mandate; and are effective in different ways. Ultimately, this has an actual impact on the end-state of the mission. It relies on and adapts classic security studies works to theoretically enrich the peacekeeping literature. The model is tested in an illustrative case study based on ethnographic work on French and Italian units in Afghanistan between 2008 and 2010.
