Efficient Propeller Selection Method for Electric UAV Using Wind Tunnel Test Data

摘要：

In this paper, a selection method of efficient electric propulsion system for small size fixed wing UAV using wind tunnel experimental data base. It will be discussed in three parts: measurements of propeller performance in wind tunnel conditions, measurements of electric motor characteristics using dynamometer, and the developments of propulsion performance prediction method using experimental performance data of its components i.e., propeller and motor. Performances of propellers were measured at low speed wind tunnel at Chungnam National University. Test section of wind tunnel has 1.25 by 1.25 meter cross section area and maximum operational speed is 70m/s. 16 RC model propellers which has 9 to 14 inch diameter were tested, at a different operating condition of advance ratio, rotating speed, torque of propeller and speed of wind tunnel were acquired. As a validation of proposed method, predicted matching points were compared with experimental results. And propulsion performance of a 10kg class close-range mini-UAV was compared for the different propeller. At a cruise condition of that UAV, an optimum propeller can be selected by the developed analysis procedure, and the enhancement of endurance can be expected from propeller change.
