Take a transformative journey through cutting-edge advances in marine technology with our definitive book. Delve into the depths of innovation as we unveil two pivotal scientific studies that are revolutionizing the field of unmanned surface cleaning vessels (USCVs). Discover the intricacies of propulsion systems with a focus on eliminating operational challenges. Traditional propellers have met their match in the form of the electromagnetic-valve-control-based water-jet propulsion system (ECWPS). Unveil visionary technology that frees USCVs from the perils of entanglement with floating objects. This system, masterfully controlled via a micro control unit (MCU), introduces a double-structure adaptation optimized for floating-object collection missions. Computational fluid dynamics (CFD) simulations unravel its prowess in various conditions, unveiling the working principles underpinning its performance. Witness the unprecedented level of design sophistication, control strategy and maneuver accuracy achieved by ECWPS. With its electromagnetic-valve array (EA), pipeline network, control system, and water-jet source, this system's hydraulic characteristic is validated through comprehensive CFD analyses and real-world experimentation. Its potential goes beyond practicality, offering a glimpse into the future of marine propulsion. Uncover the intricacies of control systems within the domain of USCVs with a dedicated ECWPS. Immerse yourself in the versatility of its three operating modes: manual remote control, self-guided cruise and self-locking remote control. Experience a seamless transition from manual maneuvering to autonomous obstacle detection and sensor-driven propulsion adjustment. Supported by a commercially available remote controller equipped with wireless communication technology, the efficacy of the proposed system is demonstrated through computational hydrodynamics simulations and prototype tests.
