An optimum design propeller, whose representative Reynolds number is 1～2×10(exp 5), has been tested in the NAL large low-speed wind tunnel. The test results, after removing the wind tunnel interference effects, were compared with predictions by a computer program based on Adkins and Liebeck′s theory. Thrust predictions show very good coincidence with test results. Torque predictions show fairly good coincidence. The difference between the theoretical predictions and experimental values are thought to be attributable to the shrinkage of the drag bucket in propeller blade sections, compared with the two-dimensional airfoil data. The aerodynamics design method of propellers working in low Reynolds number range has been established. The computer program is very useful in designing propellers for man-powered airplanes and motor soarers, as well as microwave powered airplanes.
