Artificial intelligence & future warfare: implications for international security

Recent developments in artificial intelligence (AI) suggest that this emerging technology will have a deterministic and potentially transformative influence on military power, strategic competition, and world politics more broadly. After the initial surge of broad speculation in the literature related to AI this article provides some much needed specificity to the debate. It argues that left unchecked the uncertainties and vulnerabilities created by the rapid proliferation and diffusion of AI could become a major potential source of instability and great power strategic rivalry. The article identifies several AI-related innovations and technological developments that will likely have genuine consequences for military applications from a tactical battlefield perspective to the strategic level.     

尾流模拟火箭弹空中弹道对模拟尾流生成区域的影响

为了研究尾流模拟火箭弹的空中弹道特性对模拟尾流区域的影响,建立火箭弹质点外弹道模型、阻力板和发动机空间运动微分方程以及连接绳的受力模型,得到火箭弹无控飞行、空中转向、空中分离至爆索展开入水全过程的空间运动微分方程。对尾流模拟火箭弹全程弹道进行仿真分析,着重分析不同初始射击诸元对爆索空中弹道的影响,探究初始发射角、脉冲发动机的喷管数量、点火时间以及火箭弹空中分离时间对模拟尾流生成区域的影响。仿真结果表明：初始发射角为15°时火箭弹射程和最大射高相对比较合理;火箭弹空中转向角度依赖于脉冲发动机总冲量,与点火时刻无关;空中分离时刻对爆索入水发泡区域影响不太明显,在满足转向要求和发泡区域要求的情况下应该尽早完成空中转向和分离。

【将军论坛】重要经济目标与矢量防护工程

重要经济目标是信息化战争首选的打击对象,这类目标绝大多数位于地面以上,特点突出、规模庞大、难以保密、易损性强,一旦遭受破坏后果将损失惨重,而依靠建造硬壳抵御弹药毁伤的传统防护工程对其难有大的作为。本文从新形势下重要经济目标防护陷于困局的实际出发,系统分析和梳理了传统防护工程和防护技术的特点及其应用的固有薄弱特征,提出矢量防护的创造性解决方案,为重要经济设施和预警设施、新型作战装备等位于地面的易损性目标提供了理论基础。矢量防护工程通过改变弹药的运动方向,避免弹药与目标交汇,将防护工程由“拳击式”硬顶变为“太极式”破解,为未来我国重要经济目标提供了新质防护技术。

An approach for predicting digital material consumption in electronic warfare

Electronic warfare is a modern combat mode, in which predicting digital material consumption is a key for material requirements planning (MRP). In this paper, we introduce an insensitive loss function (ε) and propose a ε-SVR-based prediction approach. First, we quantify values of influencing factors of digital equipments in electronic warfare and a small-sample data on real consumption to form a real combat data set, and preprocess it to construct the sample space. Subsequently, we establish the ε-SVR-based prediction model based on “wartime influencing factors - material consumption” and perform model training. In case study, we give 8 historical battle events with battle damage data and predict 3 representative kinds of digital materials by using the proposed approach. The results illustrate its higher accuracy and more convenience compared with other current approaches. Taking data acquisition controller prediction as an example, our model has better prediction performance (RMSE = 0.575 7, MAPE (%) = 12.037 6 and R² = 0.996 0) compared with BP neural network model (RMSE = 1.272 9, MAPE (%) = 23.577 5 and R² = 0.980 3) and GM (1, 1) model (RMSE = 2.095 0, MAPE (%) = 24.188 0 and R² = 0.946 6). The fact shows that the approach can be used to support decision-making for MRP in electronic warfare.     

Liquid phase in-situ synthesis of LiF coated boron powder composite and performance study

Among practical metal additives, boron (B) has a high volumetric heating value, making it a promising choice as a fuel additive. Although B can theoretically yield a large amount of energy upon complete combustion, its combustion is retarded by the initial presence of B oxide, which coats the surfaces of B particle. To improve the ignition and combustion properties of B powder, LiOH and NH₄F were used as precursors to synthesize uniformly LiF-coated B composites (LiF-B) in situ. The LiF-B mixture was also prepared for comparison using a physical method. X-ray diffraction (XRD), Fourier-transform infrared (FTIR), scanning electron microscope (SEM), and energy-dispersive X-ray spectroscopy (EDS) were used to characterize the morphologies and compositions of the products. The thermal and combustion properties of the samples were characterized by thermal gravity-differential thermal gravity (TG-DTG), differential scanning calorimetry (DSC) and closed bomb experiment. The XRD, FTIR, SEM and EDS results demonstrated the successful preparation of the coated LiF-B sample. The TG-DTG and closed bomb experiment results indicated that the addition of LiF decreased the ignition temperature of B powder, and increasing its reaction efficiency. DSC results show that when LiF-B was added, the released heat of underwater explosive increased by 6727.2, 7280.4 and 3109.6 J/g at heating rates of 5, 10, and 15 °C/min, respectively. Moreover, LiF-B decreased the activation energy of secondary combustion reaction of explosive system as calculated through Kissinger's method by 28.9%, which indicated an excellent catalytic effect for the thermal decomposition of underwater explosive. The results reveal that LiF can improve the combustion efficiency of B powder, thereby increasing the total energy of explosives. The mechanical sensitivity increased slightly after adding LiF-B to the underwater explosive. Compared to the underwater explosive with added B, the mechanical sensitivity of the explosive with added LiF-B was significantly lower.     

溅板式层板喷注单元燃烧特性数值分析

为了获得喷注单元结构参数对喷注器燃烧特性的影响规律,利用数值分析方法对单喷嘴溅板式层板喷注单元气-气燃烧特性进行研究,考察燃烧室特征长度及出口层喷嘴宽度对气氧/甲烷流动及燃烧特性的影响。在求解气-气燃烧流场方面,采用带化学反应的湍流N-S方程进行描述,其中化学动力学反应模型采用简化的单步9组分模型。研究结果表明:燃烧室特征长度的增大有利于特征速度效率的增加;该条件下采用溅板式层板喷注单元所对应的燃烧室特征长度约为600 mm。对比分析发现,出口层喷嘴宽度取0.15 mm时,水组分摩尔分数与热力计算值差别最大;当其值取1.05 mm时,燃烧室头部区域截面温度上升最快,取0.45 mm时上升最慢。总的来说,出口层喷嘴宽度取0.75 mm时,燃烧长度最短,燃烧效率最大。     

ISIS’s Warfare Functions: A Systematized Review of a Proto-state’s Conventional Conduct of Combat Operations

This article gives an overall assessment of ISIS’s conventional conduct of combat operations by examining their warfighting functions patterns. In sum, the approach of ISIS comprised fundamental principles: their weapons can be organized into categories, purposeful combination of these forces in keeping with the concept of combined arms combat, and hierarchical command and control executed by experienced commanders. ISIS combat groups combined the elements of formation and firepower as well as movement and mobility. The paper concludes that ISIS obviously had a vast range of conventional capabilities at its disposal and was thus able to conduct major operations.
