摘要

Many studies have proved the validation of winglets on improving aerodynamic efficiency. Similar to winglet, a suitable proplet can improve the efficiency of a propeller. The effect of proplet on propeller performance is investigated in this paper. With a cell-centered finite-volume scheme, Reynolds-Averaged Navier-Stokes (RANS) equations are solved on a chimera grid system to simulate the flow around propeller to obtain the aerodynamic performance. A propeller designed for high altitude at 20 km with a diameter of 6.8 m is used as a baseline propeller. The effect of chord length and incidence angle of proplet tip on 8the efficiency of the propeller are also considered. The simulation results demonstrate that a proper proplet leads to weaker blade tip vortex, which is helpful to improve the efficiency of the propeller.
