The anatomy of a 2030’s UUV: An acoustically stealthy soft-bodied UUV propulsion system
Current underwater reconnaissance missions have two major acoustical issues in that Unmanned Underwater Vehicles (UUV) are detectable using both passive and active sonar. Due to their hard materials, active sonar can pick up a UUV’s reflected sound and due to the propeller, passive sonar can hear the UUV. The SWORD Fish (Soft Wahoo-Inspired Oceanic Reconnaissance Drone) attempts to solve both problems by mimicking the materials and movement of the most efficient pelagic fishes. The objective of this research is to determine the key differences between the muscular structures of the Wahoo (Acanthocybium solandri) and the King Mackerel (Scomberomorus cavalla) to create the optimal stealth UUV. Digital reconstructions of these two fish provides clues as to what makes them fast. The focus of this specific project is the creation of a MATLAB code that shows how muscle movement contributes to fish locomtion. By better understanding pelagic fish locomotion, we can create a fast and efficient UUV that sounds like a fish. In doing so we can unlock the secrets of underwater stealth.
