濒海战斗舰的发展与评析——从美国濒海战斗舰(LCS)的发展探讨水面作战舰艇的发展规律

介绍了美国海军濒海战斗舰项目产生的背景和进展情况,从作战效能、经济性、战舰设计和现代化改装等方面论述了所存在的问题。本文通过对濒海战斗舰的发展过程进行分析和研究,旨在探索在信息化作战条件下轻型海上作战舰艇发展的一些客观规律。

美国海军近海战斗舰任务包的研制与发展

美国海军近海战斗舰通过安装不同任务包以完成其主要作战任务,模块化的任务包设计使近海战斗舰实现了"一舰多能"。但由于诸多新技术的应用,任务包的研制进度受到严重拖延。本文深入剖析了近海战斗舰各任务包的组成和技术性能,并从采办价格、研制进度和重量限制等方面分析了任务包的研制现状。最后,在总结近海战斗舰项目经验教训的基础上,对未来海军舰船模块化设计技术发展趋势进行展望。

濒海战斗舰的特点与短板

濒海战斗舰是一种排水量与传统护卫舰相当,同时拥有隐身能力强、速度高、回转性好、吃水浅、可重新组合的模块化结构、自动化程度高、适用于濒海/近海区域作战等特点的一种新型舰船。但是,从目前的技术观点看,濒海战斗舰还远非完美,它还存在不少的技术短板与性能的不足。本文对濒海战斗舰的现状与优缺点进行简要的介绍与分析。

濒海战斗舰气流场数值计算研究

为研究濒海战斗舰(littoral combat ship,LCS)的飞行甲板空气尾流场特性,本文采用仿真软件对“独立级”濒海战斗舰(Independence-class littoral combat ship,LCS-2)进行分析计算,将LCS-2的流场仿真数据与孤立护卫舰简化模型(SFS2)的仿真分析和风洞试验数据进行对比分析,得到LCS-2尾流场对其舰船甲板气动环境的影响。由对比结果可知:相较于SFS2,LCS-2在舰船起降甲板的大范围内均具备更适合舰载机起降的气动环境,起降甲板面积占船体总面积的比率以及机库门的倾斜程度同样对舰船尾流场存在明显的影响,研究结果能够对LCS的相关研究提供数据支撑。

水面无人船的发展与使命(英文)

The navy and other Department of Defense organizations are increasingly interested in the use of unmanned surface vehicles (USVs) for a variety of missions and applications. The term USV refers to any vehicle that operates on the surface of the water without a crew. USVs have the potential, and in some cases the demonstrated ability, to reduce risk to manned forces, provide the necessary force multiplication to accomplish military missions, perform tasks which manned vehicles cannot, and do so in a way that is affordable for the navy. A survey of USV activities worldwide as well as the general technical challenges of USVs was presented below. A general description of USVs was provided along with their typical applications. The technical challenges of developing a USV include its intelligence level, control, high stability, and developmental cost reduction. Through the joint efforts of researchers around the world, it is believed that the development of USVs will enter a new phase in the near future, as USVs could soon be applied widely both in military and civilian service.
