The invention provides a high-altitude propeller rapid iterative generation method. The method comprises the steps of: 1, determining the diameter of a propeller; 2, determining the width and the thickness of a propeller blade; 3, selecting a high-altitude propeller airfoil; 4, determining the number of blades of the high-altitude propeller; 5, determining the torsion angle of the propeller blade;and 6, determining final parameters of the propeller. According to the invention, research is carried out for characteristics of high-altitude propellers, on the basis of analyzing the influence of each design parameter of the propeller on the performance of the propeller, the environmental factor of a 20km height stratosphere is combined to serve as a variable directly related to the Mach numberof the propeller tip and the local sound velocity, and the rapid and effective method for generating the high-altitude propeller is provided based on a propeller lath theory.
