Keywords: wind tunnel testing, propeller, low reynolds number

The distributions on the surface of the rotating propeller blade were measured directly and the flow directions on the surface of blade were also obtained by photographs of tufts. By relating them, the flow characteristics and patterns on the surface of the rotating blade in low Reynolds region were verified.
