NCW背景下的潜艇对水面舰艇编队威胁判断

针对网络中心战(NCW)背景下水面舰艇编队反潜的实际情况,采用层次分析理论探究潜艇对水面舰艇编队的威胁判断问题。将编队攻击意图系数和编队攻击达成系数引入威胁判断,从编队攻击意图推理、攻击紧迫程度和攻击达成可能性三个方面建立了潜艇对于威胁的总体感知模型框架。该模型框架较之以往更全面地考虑了水面舰艇编队对潜艇的威胁因素,为下一步刻画潜艇对威胁的感知提供基础。     

海军特种作战军事概念格式化描述框架和模板研究

介绍了海军特种作战军事概念格式化描述的方法。对海军特种作战军事概念格式化描述的要求进行深入分析,得出格式化描述的基本思路：用面向对象的方法对海军特种作战军事行动进行分解,给出一套规范和格式,使军事人员对军事行动的格式化表述清晰地提供出技术人员所熟悉的面向对象的概念和机制。根据这种思路对海军特种作战军事行动进行分析,抽取出格式化描述的五个要素：作战单位、动作、作战行动、信息和作战环境,从而建立海军特种作战军事概念格式化描述的框架并详细研究了上述五个要素的描述框架和模板结构。     

Swedish–Finnish naval cooperation in the Baltic Sea: motives,prospects and challenges

Recently, Finland and Sweden decided to substantially deepen their defence cooperation and this project involves creating a bilateral standing Naval Task Group (SFNTG). The present article aims at examining the deepening naval cooperation between Finland and Sweden from a regional integration perspective, focusing on its motives, current challenges and future prospects. Driven by perceptions of common challenges and desires for cost-effectiveness, and strengthened by recent successes on sea surveillance and a combined Amphibious Task Unit, the bilateral project has considerable potential to achieve success. To fulfil its objectives, substantial legal changes in both countries are required to allow the use of force on each other’s territorial waters. To cater for the requirement of not conflicting with EU, NORDEFCO or NATO cooperations, the bilateral Task Group must operate according to NATO standards and by using English as the language in command and control. The costs of adjusting the naval units to NATO’s technical requirements are far from negligible and this issue still remains to be solved. If Finland and Sweden manage to incorporate new policies, common structures and common organisational norms among their navies, an even deeper integration, as in Belgium and the Netherlands, are conceivable.

舰载导航系统的舰炮对海校射方法

测量距离方向法校射是我海军舰炮火控系统对海校射的主要方法,但在传统校射模型中,偏差测好时刻发射舰位置由发射时刻的发射舰位置推算而得.若直接用发射舰航向航速推算,则由于瞬时航向航速扰动.误差较大;若通过瞬时航向航速累积推算,则随着时间的增加,累积误差也很大.将舰载导航系统引入舰炮校射.利用舰载组合导航系统直接测得发射时刻和偏差测好时刻的发射舰位置.从而建立校射模型.仿真结果表明,该方法对提高舰炮校射精度,缩短系统反应时间,增强舰炮武器系统的作战效能有着重要的现实意义和军事意义.     

The U.S. Navy's task forces: 1–199

ABSTRACT

Grouping warships for combat has evolved greatly over the centuries. In the early 1940s, the United States Navy began to group its warships for combat in much more flexible task forces than the previous single-type-of-warship formations. This system has evolved and spread to naval forces ashore but remains fundamentally unchanged. It now covers numbers between 1 to over 1000, of which the most prominent is the first 100 or so which U.S. Navy combat forces use. The numbered fleets worldwide utilize the series covering 20-79; 1-19 and 90-99 appear to be reserved for special allocations and Commander, Pacific Fleet; numbers over 80 to the Atlantic; 100-119 for Northern Europe and briefly Tenth Fleet; the 120 series for Second Fleet as a Joint Task Force leader; the 150 series for Naval Forces Central Command; and the 180 series for Atlantic Fleet and now-Fleet Forces Command.     

Bi‐objective missile rescheduling for a naval task group with dynamic disruptions

This paper considers the rescheduling of surface‐to‐air missiles (SAMs) for a naval task group (TG), where a set of SAMs have already been scheduled to intercept a set of anti‐ship missiles (ASMs). In missile defense, the initial engagement schedule is developed according to the initial state of the defensive and attacking units. However, unforeseen events may arise during the engagement, creating a dynamic environment to be handled, and making the initial schedule infeasible or inefficient. In this study, the initial engagement schedule of a TG is assumed to be disrupted by the occurrence of a destroyed ASM, the breakdown of a SAM system, or an incoming new target ASM. To produce an updated schedule, a new biobjective mathematical model is formulated that maximizes the no‐leaker probability value for the TG and minimizes the total deviation from the initial schedule. With the problem shown to be NP‐hard, some special cases are presented that can be solved in polynomial time. We solve small size problems by the augmented ? ‐ constraint method and propose heuristic procedures to generate a set of nondominated solutions for larger problems. The results are presented for different size problems and the total effectiveness of the model is evaluated.     

舰炮身管的模态分析与多目标优化

舰炮的炮口扰动是影响舰炮射击精度的重要因素。为了减少舰炮的炮口扰动,优化身管结构,建立了柔性身管的ABAQUS有限元模型,将有限元模型的模态计算值与模态试验值进行比较,发现建立的柔性身管有限元模型是合理可行的。提出了混沌量子粒子群算法与动力学联合优化的方法,进行身管和炮口的多目标优化。优化结果表明,优化后炮口中心的线速度、角速度和角位移与优化前相比显著减小,身管质量有所降低,结构更加合理,该优化方法有效可行,为下一步全炮总体优化设计提供了一定的借鉴。
