Aiming at propulsion system of stratospheric, a high altitude propeller was designed. Avoiding the singularity of equations in the iterative process, the interference angle equation was improved and the designed propeller was calculated by the strip theory. The three-dimensionalNavier-Stokes equations were used to simulate the complex flow around the designed propeller and its aerodynamic characteristics were analyzed, in which the k - ω turbulence model was used. The accuracy of the numerical simulation was determined by the calculation of different grid numbers. The results show that the designed propeller can satisfy the requirement of propulsion system and the strip theory and numerical simulation can provide the reference for the design of stratospheric propeller.
