Part V: Unmanned Submersible Research Report (two) Unmanned submersible American unmanned submersible Bluefin (Tuna) Series UUV U.S. Bluefin (Tuna) series UUV based on mine detection and lightning protection Bluefin Robotics has produced about 50 AUV platforms in the series, including 21-inch (533mm) BPAUV mounted on the US Navy surface ship, 9-inch for VSW (very shallow sea) and MCM (anti-mine warfare). The 229mm) portable Bluefin-9 system, and the Bluefin-12 (324mm) system for flexible use and operation. Features of the series: precise navigation after dive, long distance through the operating area; in place waiting for instructions or explosion threats; flexible payload capacity; balance between load and UUV size; stable at 0.5-5kn speed Sensor platform. When Bluefin is used as a reconnaissance aircraft, it undertakes a series of observable tasks, including: (1) transporting supplies to swimmers on shore, on boats, or in water; (2) intercepting and tracking targets; (3) Information acquisition, surveillance and reconnaissance (ISR) on the coast, seafront and port; (4) Communication links between shore personnel and facilities on the sea. It is mainly used for port security and MCM. (1) Port security: UUV is used to monitor and reconcile intruders (firstly, the aircraft is anchored on the seabed as much as possible, and its sensors are used to detect intruders. When an intruder is detected, the aircraft reports the detection results and intercepts the intruders or trails. The sensor can be precisely positioned for the intruder and can be contacted by the port). (2) MCM: 1) establishment of seabed imaging; 2) survey; 3) intelligent database - determining the location and extent of possible minefield waters; 4) similar mines at the bottom, potential buried mine location and density; Sound and magnetic propagation characteristics within a geographical range. Bluefin's AUV has the ability to run a fairly long path from the deployment point, perform submarine imaging and return to the original path. When these capabilities are implemented in MCM operations, they are completely concealed. (1) Bluefin-9 In 2006, the Bluefin-9 UUV was put into use for anti-mine and shallow sea surveys. Its small size makes it easy to operate and operate, maintains the forward direction and can be quickly turned in the dive to achieve an optimum exploration rate. The system was designed to allow two people to operate UUV on a small boat, including downloading new probe data, replenishing energy, and configuring new tasks; all of which can be completed in less than 15 minutes. Sonar imaging played back with Bluefin's view software, including a waterfall map, a waterfall map and a chart (UUV track, current location and all contact locations). Bluefin-9 features: rapid reversal in water; simple operation; modular and field maintainability; precise navigation. Bluefin's View Software Review Sonar Imaging The Bluefin-9 has four modules: the main electronics compartment, pressure-resistant batteries, data modules and hinged duct thrusters. Bluefin's View Software Review Sonar Imaging is shown below. The complete software includes: Bluefin's mission plan, Dash-board and user's data analysis interface, which do not require much training for the operator. When launched, the mission plan appears in front of the user in the form of a chart. The task file obtained by the operator can tell the UUV speed, depth, sonar beam width, route spacing, and walking length and distance. When the module is implanted in the aircraft, the UUV can begin its mission. Any kind of task can be pre-set to the data module, so the operator does not need to do the program settings for the task on the boat. A task can be set up in 5 to 10 minutes. Its core software is also applied to Bluefin-21. (2) Bluefin-12 Bluefin-12 provides users with a platform with load flexibility and capabilities unmatched by similar products. Maximizing payload and performance with intelligent packaging with cutting-edge technology similar to light torpedo structures. In August 2006, the US Navy signed a contract to complete a UUV-based mine detection system by Bluefin. Each SMCM/UUV-2 system consists of two Bluefin-12UUV platforms and all auxiliary equipment that needs to operate and maintain the system. Each Bluefin-12 UUV carries a dual-frequency synthetic aperture sonar as its primary sensor, as shown in the figure below. Bluefin-12 features: simple operation; strong endurance; strong load capacity. Bluefin-12 (3) Bluefin-21 In September 2005, the US Navy signed a contract to complete the UUV mission for the coastal surface ship by Bluefin. The mission module consists of two Bluefin-21 robots and includes all the necessary equipment to operate and maintain the aircraft. The module includes communication systems, battery charging stations, tail cone parts, and human factor structural changes. This program provides an opportunity for the Bluefin-21 platform to evolve from the ONR (Naval Research Bureau) trial design to the successful transition of the Operational Platform of the Bohai Battleship (LCS). Bluefin-21 features: reconfigurability and customizability; reliability; flexibility; high resolution; precision navigation. Outstanding sonar imaging (the standard configuration of the Bluefin-21 can carry a high-performance 455 kHz side-scan sonar, horizontal track provides 10 cm resolution, and vertical track provides 7.5 cm resolution. Bluefin's high-resolution sensors and unique precision navigation allow the Bluefin-21 to find mines within 8 square miles per dive, which is unmatched by other devices. Precise navigation (Bluefin-21 high-performance and self-contained navigation system does not require the use of sonar buoys. The submersible can fuse AHRS (Azimuth Azimuth Reference System) and DVL (Doppler Logging) when diving and regularly floating GPS data updates. The data of this navigation system has excellent navigation performance. In the US Navy's exercise, Bluefin's positioning of the target is within 3m radius. (4) BPAUV BPAUV (Battlespace-Preparation AUV) is a small fast underwater robot developed by Bluefin Robotics. It is a key part of the LCS mission module and provides important intelligence, surveillance and reconnaissance capabilities for mine warfare and other missions. The BPAUV uses a low-resistance fairing with a single hinged duct thruster that can be operated from a ship or boat. In addition, the 455kHz side-scan sonar on the submersible provides an image with a resolution of 7.5-10cm. Under the contract, the US Navy will purchase a BPAUV system, including two submersibles and support equipment. The BPAUV weighs 800 pounds, is 122 inches long and 21 inches wide. It is powered by a lithium battery and runs at 3kn. Once deployed from a mine warship, it is completely autonomous to sail according to a pre-designed route. The BPAUV features side-scan sonar to detect and identify mines in front of the ship. The main parameters of BPAUV include: total length: 305cm; diameter: 53cm; weight: dry weight 220kg; wet weight 360kg; working depth: 270m. Features of BPAUV: 1) Flexibility: As shown in a series of fleet combat experiments, the Bluefin-21 BPAUV secretly collects accurate marine biodistribution and seabed classification data for use in the early stages of battlefield space preparation. It can operate in a variety of climatic conditions, regardless of day or night, without loss of data accuracy, can be deployed from a small boat of not less than 40 feet. 2) Precise navigation: BPAUV can provide 0.5% navigation accuracy without assistance in real time, and the navigation accuracy after post-processing can reach 0.2%. 3) Wide operating range: Bluefin's unique battery mode allows for a quick reversal on the deck for up to two hours, allowing the battery to be exchanged without opening the pressurized chamber. The full-load battery provides the submersible with the capability required for a survey of 18h at a speed of 3kn per hour, with a working range of up to 150km in a water depth of 200m. The Bluefin operator's intuitive software makes the adaptation process fast and precise.
