A Power-speed Performance Analysis Approach for the Optimization of Hull Geometry in Autonomous Underwater Vehicles

Abstract

Optimization of the geometric parameters of the hull of autonomous underwater vehicles (AUVs) is a crucial factor affecting their hydrodynamic properties, energy efficiency, and functional suitability. This study analyzes the challenges associated with the miniaturization of structures, in particular, the limitations that arise when reducing the size of the vehicle. The main attention is paid to determining the dimensions of the hull that minimize losses in speed and propulsion performance. A comparative evaluation of configurations with different values of diameter and length was carried out, which made it possible to identify the advantages of options with an increased length-to-diameter ratio (L/D). The proposed approach takes into account power limitations and is focused on achieving the target performance characteristics. The obtained results allow us to better understand the relationship between the hull geometry, power consumption, and dynamic properties, which is important for ensuring the efficiency of AUVs in real-world conditions.
