从海洋开发和海军建设出发,介绍了一种正在研发的低成本小型潜航器,这种小型潜航器的航行、下潜和上浮全部借助海流能量和浮力作用,隐蔽性好,不消耗电池能量。而锂电池组的能量主要用于传感器的探测、通信设备联络和电脑运行,偶尔用于泵、舵、电池移动等。一次充电一般可以维持潜航器航行几个月,航程达几千里。 Starting from the development of the oceans and the construction of the navy, a low-cost small submersible is being developed. The sailing, diving and floating of such small submersibles are all based on current energy and buoyancy and have good concealment and no battery energy consumption. The lithium battery energy is mainly used for sensor detection, communications equipment and computer operation, and occasionally used in pumps, rudder, battery movement and so on. A charge can generally maintain the submarine sailing months, voyage up to several thousand miles.
