In this paper, the methods of reverse reconstruction and parametric modeling of the propeller are mainly studied. The torsion angle distribution and the pattern of the leaf-type stacking of the existing propeller model are optimized. In this paper, the propeller is taken as an example, and its reconstruction and parametric modeling are carried out. Numerical calculation techniques based on high-precision algorithms such as structured rotating grid and N-S equation are established and tested by experiments. Based on this, the CFD calculation of the propeller, the analysis and optimization of the blade twist angle and the stacking method are carried out to provide the help of the existing blade pull-down power
