The three-dimensional Navier-Stokes equations were used to simulate the complex flow around a high altitude propeller and its aerodynamic characteristics were analyzed, in which the k-ε turbulence model was used. In accordance with similarity criteria such as equal Reynolds number and equal advanced ratio, the scaled model test of high altitude propeller was carried out. The simulation results are in good agreement with test results. The feasibility of the numerical simulation method for aerodynamic characteristics calculation of high altitude propeller is proved, and provides reference basis for the design and test of high altitude propellers.
