description	The invention provides a variable-section rim propeller optimization design method based on section cylindrical coordinate change. The variable-section rim propeller optimization design method comprises the following steps that geometric characteristic parameters of a mother type propeller are obtained; selecting chord lengths and thicknesses of wing-shaped sections of the blades and the guide pipes as well as changed section positions and quantity as design parameters, and determining a parameter change range and a minimum sample difference; sampling by using a low-difference sampling sequence according to the design parameters to obtain a sample database; selecting a sample and changing profile value points of a blade section and a conduit section according to the sample to generate a blade, and then combining to generate a rim propeller model; and the hydrodynamic performance of the rim propeller model corresponding to the sample is accurately obtained by combining a finite element theory hydrodynamic perf
