It is a technical difficulty to calculate the hydrodynamic parameters when autonomous underwater vehicle (AUV) carries some complex shape appendages (equipment). The general hydrodynamics simulation software CFX and the SST turbulence model were used to calculate the hydrodynamics of AUV with CTD and GPS/Beidou antennas, obtain the AUV hydrodynamic variation of three models and analyze the influence of different appendages on the hydrodynamics of AUV. The results show that the horizontal of AUV with appendages is asymmetric, the pressure and speed change rapidly at the appendages, resulting in the great change of AUV hydrodynamic parameters and the flow field. The numerical results pro- vide a reference frame for the engineering design of AUV. [ABSTRACT FROM AUTHOR]
