能上天，也能下水，你见过这样的水陆两栖飞行器吗？近日，一项名为“TJ-FlyingFish”（同济飞鱼）的水空跨域巡航器原型机，先后被《新科学家》、New Atlas等国际科技杂志报道。

《新科学家》网站：“潜水无人机飞行入水自由切换”

“既可以像标准四轴无人机那样飞行，也可以在水下作业，这是一款为工程师和搜救团队打造的无人机”

New Atlas网站：“同济飞鱼，天上翱翔，水下畅游”

“同济飞鱼”是由同济大学上海自主智能无人系统科学中心（以下简称“科学中心”）、全国重点实验室与香港中文大学团队联合研发的创新成果。

TJ-FlyingFish was jointly developed by a team of scientists from the Shanghai Research Institute for Intelligent Autonomous Systems under the Tongji University and the Chinese University of Hong Kong.

该水空跨域巡航器原型机可以在水和空气两种介质中自由切换，可应用于资源勘探、灾害搜救以及工程检验等场景。

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.

Possible applications include resource exploration, search and rescue missions, and engineering inspections.

这款名为“TJ-FlyingFish”（同济飞鱼）的水空跨域巡航器原型机，重量为1.63千克，轴距为380毫米，采用了搭载水空两用推进单元和舵面倾转机构的四旋翼构型设计，具备跨域穿梭能力及双域巡航能力，可在空中悬停6分钟，在水下巡游约40分钟。

Dubbed TJ-FlyingFish, the aerial-aquatic quadrotor weighs 1.63 kg with a wheelbase of 380 mm.

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.

此外，该巡航器本体搭载了由GPS、惯性测量单元(IMU)、深度计等组成的跨域定位导航系统，具备水下、空中和跨介质过程中的自动操控能力。

The quadrotor is equipped with a cross-domain positioning and navigation system consisting of GPS, inertial measurement unit, depthmeter and mini Doppler velocity log, which enables autonomous control during its amphibious journey.

无人机自带潜水功能，这样的黑科技，是不是很科幻呢？
