Note (General)
When an aircraft powered by an electrical motor (electric aircraft) with rechargeable batteries descends, it is easy to utilize wind power for charging the batteries by rotating propeller passively. In this study we examined characteristics of propeller-blades to regenerate energy in some conditions in a wind tunnel by using model-aircraft propellers and main rotor for model-helicopter. The changed conditions are follows; 1) wind speed, 2) blade diameter and 3) blade pitch angle. Based on the results of this experiment, it is found that electric aircraft can regain 10% of potential energy while descending. In addition, slipstream measurements were conducted and local drag and local thrust of blade elements were calculated. These results demonstrated that local drag is mainly generated by blade elements in r/R less than 0.6.
