Deep-sea floating platform is the future trend of underwater equipment technology in the direction of information and intelligence, which is of great significance for fundamentally reversing the strategic security situation at sea and effectively rejecting strong enemies in the deep sea. According to the characteristics of the deep-sea floating platform, such as long-term service, rapid underwater floating and deep pressure seal, the shape design of a large-scale underwear vehicle and hydrodynamic characteristics forecast based on shape of the rotating body is proposed, which focuses on solving the low resistance requirements of the platform when floating without power. After theoretical estimation and CFD software simulation verification, the simulation results meet the design requirements, which provides important technical support for further research on the unpowered deep-sea floating platform.
