Design and Optimization of a Compact and Versatile Portable Autonomous Underwater Vehicle for Efficient Underwater Exploration

Abstract

This paper focuses on the design development aspects of a portable autonomous underwater vehicle (AUV). The design optimizations are carried out to enhance the AUV's performance and functionality. The propulsion system configuration is carefully optimized, considering the size and type of the airfoils used, to maximize efficiency and maneuverability. Additionally, the placement of the Doppler Velocity Log (DVL) is strategically determined to maintain the hydrodynamic characteristics of the AUV while enabling precise navigation. To ensure connectivity and access to essential infrastructure, the GPS and communication devices are meticulously mounted, allowing for seamless Wi-Fi and satellite communication. The design and placement of actuators for control surfaces in the appendage are carefully considered, enabling precise control and maneuvering in different underwater environments. Moreover, the thruster design is optimized to achieve an operational speed of 4 knots, ensuring efficient underwater exploration capabilities. Special attention is given to the water-resistant property of the AUV interior, safeguarding sensitive components and ensuring reliable performance in harsh underwater conditions. The placement of controllers, sensors, power management devices, and communication systems inside the dry hull is thoughtfully designed, ensuring their protection from water ingress. This arrangement guarantees the reliable functioning of these vital components, facilitating efficient data collection, processing, and communication. Through comprehensive design optimizations, this paper presents a portable AUV with improved propulsion system configuration, precise hydrodynamic characteristics, efficient communication infrastructure, optimized control surfaces, and enhanced speed capabilities. The design considerations outlined in this paper contribute to the advancement of portable AUV technology, enabling efficient and reliable underwater exploration for various applications, including scientific research and marine inspections.
