Unmanned surface vehicle (USV) is a surface ship with autonomous planning and navigation capabilities, and can independently complete tasks such as environmental perception, target detection and tactical attack. When it comes to unmanned boats, we have to mention "Tianxing-1", which holds an amazing record and is the fastest unmanned boat in the world today.
Unmanned boats have now become the focus of research and development in countries around the world
It is reported that the "Tianxing-1" unmanned boat is the first model in the field of unmanned boats supported by the national 863 program. The boat adopts a deep V-shaped boat type, with a sharp head, which has the effect of reducing water resistance and increasing speed. "Tianxing No. 1" is 12.2 meters long, full load displacement of 7.5 tons, width of 3 meters, using diesel-electric hybrid (diesel engine + water jet propulsion / surface propeller), its maximum range of 1000 kilometers, maximum speed of 30 ~ 80 knots, the maximum speed not only created a record in the field of unmanned boats, but also in the field of military ships, it is also faster than the fastest hydrofoil speedboat. At the same time, the propulsion system also uses silent noise reduction technology, and the option to use silent propellers is used.
The hull of "Tianxing-1" is made of high-performance and high-strength composite materials, with a payload of 1,000 kg, which can carry GPS, Beidou satellite communications, radio/image transmission radio, photoelectric pods, radars, inertial navigation systems and other equipment and equipment, and can also be equipped with weather stations, temperature and salt depth meters, side-scan sonar, multi-beam sonar and other equipment according to the needs of the mission.
At present, the world's fastest unmanned boat "Tianxing-1"
Due to the fully modular mission load design, Tianxing-1 can quickly replace the task load as needed, and independently complete multiple tasks such as marine hydrometeorological information monitoring, seabed topography and geomorphology scanning and mapping, and head-to-end observation. Typical applications include marine environmental monitoring, scientific investigation, search and rescue at sea, seaport security, military applications, and multi-vessel coordination. Judging from the appearance, the entire hull of the "Tianxing-1" is clean and tidy, the superstructure adopts a distinctive polyhedral stealth structure design, and the target in the water is extremely small, no more than one percent of a small fishing boat of the same tonnage, and it is difficult for the enemy's detection and attack means to be effective against it.
"Tianxing-1" has four working modes: manual operation, remote control, semi-autonomous and fully autonomous, its advanced control system can achieve high-precision tracking of the target track, and its environmental cognition system adopts advanced target detection and recognition algorithms, combined with real-time modeling technology, which can quickly fuse and process the environmental target information obtained by radar, visible light, infrared and other sensors, and form an accurate cognition of the surrounding environment information. The wireless communication range of the boat is 20 kilometers over-the-horizon.
"Tianxing-1" has four working modes: manual operation, remote control, semi-autonomous and fully autonomous, and its advanced control system can realize high-precision tracking of the target track
Under the guidance of the autonomous decision-making system, Tianxing-1 can efficiently complete various tasks and missions in any seaworthy waters, and can carry out autonomous danger avoidance for static and dynamic obstacle targets in complex environments. and autonomous tracking and pursuit of dynamic suspicious targets. For unmanned boats, high speed is not an indicator that is difficult to achieve, and what is more difficult to do is how to make the unmanned boat independently identify and avoid obstacle targets at high speed, and how to intelligently pursue suspicious targets, the intelligent judgment and algorithm behind this are very technical.
"Tianxing-1" is small, lightweight, and high-speed; It is convenient for ship-based, quick response and strong maneuverability; Good concealment and strong survivability; The active sea area is wide, and the effective use time is long; There is no fear of casualties; Low cost of construction and use; Modular design and construction and other advantages, the application prospect is broad. At present, "Tianxing-1" has been successfully delivered to users.
