“维比克”轮侧推器的改装修复

在船舶修理过程中，经常会碰到意外的困难，需要灵活的处理。本文以实例介绍了侧推器的改装修复过程。     

A new marine propulsion system

A new marine propulsion system is proposed . A small liquid sodium cooled reactor acts as prime mover; alkali-metal thermal-to-electric conversion (AMTEC) cells are employed to convert the heat energy to electricity; superconducting magneto-hydrodynamic thruster combined with spray-water thruster works as propulsion. The configuration and characteristics of this system are described. Such a nuclear-powered propulsion system is not only free of noise, but also has high reliability and efficiency. It would be a preferable propulsion system for ships in the future。

矢量推进混合型水下运载器的概念设计研究

文章介绍了一种基于矢量推进方式的新型水下运载器的概念设计,提出了使用光纤微电缆(FOMC)连接蓝牙浮标实现半无线通信并应用于水下运载器的理念,对运载器的本体设计和控制方式进行了阐述,另外还基于MATLAB对控制上位机进行了仿真。作为一种新型水下机器人,它可以通过半无线控制,轻便灵活,实现五个自由度的运动,能在半人工控制和半自主运动的模式下,实现水下悬停、定深运动并能灵活回转和爬升下潜等,成为一种兼具ROV和AUV优点的混合型水下半自主航行器。
