Abstract

A propeller airfoil design method and a terminal device. Said method comprises: obtaining a design variable and an objective function of a propeller airfoil (S1); according to the design variable and the objective function, establishing an optimized model and a fitness function for the propeller airfoil (S2); according to the optimized model, generating N initial populations, where N is a positive integer greater than or equal to 2 (S3); randomly initializing the N initial populations so as to obtain N initialized populations, wherein each of the initialized populations contains several individuals, each individual being a design plan data mapped from the design variable (S4); according to the fitness function, calculating the fitness value corresponding to each of the individuals in the N initialized populations (S5); if the fitness values exceed a fitness threshold (S6), outputting the design plan data corresponding to the individual in the initialized populations having the highest fitness value (S7).
