Sea Spider-Type Multifunctional High-Speed UAV-Boat Coupled System

The demand for waterborne patrol missions has intensified due to the growing need to safeguard maritime security and protect marine rights. In response to this challenge, an integrated unmanned aerial vehicle and vessel system is presented, capable of performing a wide range of tasks, including but not limited to coastal surveillance, precision military operations, and emergency maritime rescue. The sea spider-type vessel features a deformation mechanism driven by hydraulic transmission rods, enabling smooth and frequent transformations while maintaining operational stability and radar stealth. To address the hydrodynamic resistance encountered by the hull during movement, the Volume of Fluid (VOF) method and STAR-CCM+ software were employed for resistance analysis. Extensive physical model testing indicates that the system can achieve high-speed and stable navigation, significantly expanding reconnaissance coverage. Furthermore, its modular design supports mission-specific payload configurations, demonstrating strong potential for both military and civilian applications.
