This paper presents the structural design and manufacturing aspects of a Mini Mobile Target Torpedo (MMTT) for underwater applications. The MMTT is a small Unmanned Underwater Vehicle (UUV) designed to mimic the acoustic and hydrodynamic signatures of larger submarines, making it an effective training tool for naval forces. The focus of this research is on the structural design and manufacturing techniques employed to ensure the MMTT's reliability, maneuverability, and durability in challenging underwater environments.

The paper discusses the initial design considerations, including size, weight, and payload capacity, which are optimized to achieve the desired performance characteristics. A comprehensive analysis of the hydrodynamic forces acting on the MMTT is conducted using computational fluid dynamics (CFD) simulations, enabling the refinement of the vehicle's shape and hydrodynamic features to minimize drag and enhance maneuverability.

To ensure the structural integrity of the MMTT, advanced materials and fabrication techniques are employed. The selection of suitable materials, such as high-strength composites and corrosion-resistant alloys, is discussed, considering factors such as weight, buoyancy, and hydrodynamic properties. The manufacturing process, including mold design, composite layup, and curing techniques, is detailed to ensure the production of a robust and reliable vehicle.

Furthermore, the paper presents the integration of propulsion and control systems into the MMTT's structure. The placement of thrusters, rudders, and control surfaces is carefully considered to optimize maneuverability and stability. The communication and power systems are also seamlessly integrated, allowing for efficient and reliable operation of the MMTT during missions.

Finally, the paper discusses the testing and validation procedures conducted to verify the structural design and manufacturing process. Various tests, including hydrostatic pressure testing, vibration testing, and functional testing, are performed to ensure the MMTT's compliance with operational requirements and safety standards.

The outcomes of this research provide valuable insights into the structural design and manufacturing considerations for developing Mini Mobile Target Torpedoes. The presented methodologies and techniques can be adapted and extended for the design and fabrication of other UUVs, contributing to the advancement of underwater robotics in defense and civilian applications.
