To study the geometric parameters of low rotation propeller for hybrid underwater glider,the propulsive efficiency of the propeller was analyzed.The coordinates of blade characteristic points were calculated using curve algorithm,and the three-dimensional solid model built using 3D modeling software.The propeller hydrodynamic performance was analyzed according to the lifting line theory to study the impacting factors of the propulsive efficiency such as the diameter,rotation velocity,the cord to diameter ratio and thickness distribution.The propeller hydrodynamic performance was verified by the fluid dynamics analysis software.The results of comparative analysis show that the diameter and the rotation have a great impact on the propulsive efficiency,and that the cord to diameter ratio and thickness distribution have little effect on the propulsive efficiency.In addition,the hub has little effect on the propulsive efficiency through fluid dynamics analysis.At the same time,the parameters of the propeller with the features low rotation,high efficiency can be obtained.The results show low load propeller has high efficiency under conditions of low rotation,large diameter,small chord distribution and small thinkness distribution,and the propulsive efficiency up to 0.73.
