05 - PropulsionSTUDY ON THE AERODYNAMIC CHARACTERISTICS OF HIGH-ALTITUDE PROPELLERS WITH PROPLETSX. Yang¹, J. Xu¹, B. Wang¹, C. Song¹, S. Zhang¹; ¹School of Aeronautics, Northwestern Polytechnical University, China The proplet is able to reduce the energy loss of the flow around the propeller tip, and is very promising for the efficiency improvement of a high altitude propeller. The influence of the parameters of the proplets has been studied systematically and the results will provide design criteria for an efficient proplet. |
