Modular USV Towfish (Free-Flooding Fairing) - Blue Robotics Compatible · 模型 158758
This is a modular, 3D-printable Towfish designed to be towed by Unmanned Surface Vehicles (USVs) for acoustic mapping. It features a free-flooding architecture and is specifically dimensioned to house a commercial Blue Robotics watertight enclosure alongside a Side Scan Sonar. Key Features: Hydrodynamic Design: The outer hull is generated using Myring hull equations (620 mm total length) optimized to minimize drag, while the tail assembly utilizes NACA 0012 symmetrical fins for maximum directional stability. Free-Flooding Architecture: Designed as an external hydrodynamic fairing. Water floods the interior to equalize pressure, while the critical electronics remain safe inside the internal pressure housing. Modular 4-Piece Assembly: The CAD model is segmented into 4 parts to fit standard 3D printer build volumes. The pieces feature alignment holes (designed for 3mm filament segments as pins) and structural tabs ("ears") to be secured with zip ties and epoxy adhesive. Passive Stability: The internal layout is engineered so the Center of Gravity (CoG) remains well below the Center of Buoyancy (CoB), guaranteeing a natural pendulum effect to counteract roll and pitch. This open-source design was developed as part of a Bachelor's Thesis in Marine Sciences and Technologies at the Universitat Politècnica de Catalunya (UPC). Printing recommendations: Print in PETG or PLA. High infill (e.g., 40-50% Gyroid) and thick perimeters are recommended to withstand towing forces and mechanical stress in marine environments.
