This paper is based on the CFD method to numerically study the manoeuvrability of an underwater vehicle. By predicting the straight-line navigation resistance of the underwater vehicle, the results agreed well with the test values, which verified the accuracy of the numerical method. In addition, two methods of static and dynamic prediction were used to solve the self-propulsion point based on the body force method for the SUBOFF underwater vehicle with E1619 propeller, and ultimately the relative errors of the two methods of the propeller rotational speed and thrust were -1.56% and -4.54%, respectively. The performance parameters of the propeller thrust coefficient ΚT and torque coefficient Κwere also close to each other base on the two methods, and the relative errors were all within 3%. This paper provides a good foundation for the prediction of zigzag test, turning circle and other motions of the subsequent underwater vehicle, which is of great significance.
