Based on the Reynolds-averaged Navier-Stokes control equation and the unstructured grid rotation / stationary slip surface technology, the aerodynamic layout and synergistic mechanism of the propeller tip-winglets near the space propeller are studied. Multiple networks of stationary and rotating domains Grid layout strategy and transfer / static slip surface technology, the development of efficient propeller flow field and performance analysis methods; through the development of a small upturned winglets and other small wing propeller layout research, initially established a foundation The results show that the propeller layout of the tip winglets is a reasonable and feasible technical approach to improve the aerodynamic efficiency near the space environment.
