Simulation Study of Composite Propulsion Mechanism of Cycloidal Propellers

This paper conducts a numerical simulation to investigate the propulsion dynamics of an underwater vehicle outfitted with a dual cycloidal propeller configuration., Exploring the effects of blade spread length and rotational speed on the underwater performance of a navigational vehicle. First, the kinematic analysis of the vehicle is performed to determine the computational parameters of the hydrodynamic performance of the vehicle and to establish a simulation model of the vehicle. N ext, the simulation analysis of the vehicle under different conditions is carried out using CFD methods. The results show that the vehicle equipped with pairs of propellers can travel stably, and the rotational speed and blade spread length have a positive effect on the propulsion speed of the vehicle. The results provide an important reference for the theoretical research and physical development of the subsequent Cycloidal Propellers.
