Researchers have developed a prototype of a quadrotor that can both fly in the air and swim underwater‚ making it suitable for a wide range of applications․ Dubbed TJ−Flying Fish, the aerial−aquatic quadrotor weighs 1.63kg with a wheelbase of 380 mm.
研究人员研制出一种既能在空中飞行又能在水下游泳的四旋翼原型机，适用于广泛的应用。被称为TJ−飞鱼，空中–水生四旋翼重1.63公斤，轴距380毫米。
It adopts special designs in the propulsion and thruster configuration to cope with different fluid properties of water and air‚ making it capable of hovering in the air for six minutes or swimming underwater for about 40 minutes․ For propulsion‚ the operating range is switched for the different mediums by the dual−speed propulsion unit‚ providing sufficient thrust and also ensuring output efficiency. For thruster configuration‚ thrust vectoring is realized by the rotation of the propulsion unit around the mount arm‚ thus enhancing the underwater maneuverability․ The quadrotor is equipped with a cross−domain positioning and navigation system consisting of GPS‚ inertial measurement unit‚ depth meter and mini Doppler velocity log‚ which enables autonomous control during its amphibious journey․ TJ−Flying Fish was jointly developed by a team of scientists form the Shanghai Research Institute for Intelligent Autonomous Systems under the Tongji University and the Chinese University of Hong Kong. Possible applications include resource exploration‚ search and rescue missions‚ and engineering inspections.
它在推进和推进器配置上采用了特殊设计，以应对水和空气的不同流体特性，使其能够在空中悬停6分钟或在水下游泳约40分钟。在推进方面，通过双速推进装置切换不同介质的工作范围，提供足够的推力，也保证了输出效率。对于推进器配置，推力矢量是通过推进单元绕臂旋转来实现的，从而增强了水下流动性。这架四旋翼飞行器配备了由GPS、惯性测量单元、测深仪和迷你多普勒速度日志组成的跨域定位导航系统，能够在两栖航行过程中实现自主控制。TJ−飞鱼是由同济大学上海智能自主系统研究所和香港中文大学的一组科学家联合开发的。它可能应用于包括资源勘探、搜救任务和工程检查。
Note
It is an effective means to solve the cross-domain collaboration of unmanned systems to develop an unmanned platform with cross-domain shuttle and cruise capability, so that it can act as a messenger in the cross-domain collaborative system and realize the information transmission and interaction between the cross-media nodes.
研制具有跨域穿梭和巡游能力的无人平台，使其在跨域协同系统中充当信使角色，实现跨介质节点间的信息传递与交互，是解决无人系统跨域协同的有效手段。
