Automated Dynamic Propeller Testing at Low Reynolds Numbers

Experiments were conducted on small propellers using a motor dynamometer in a wind tunnel. The effects at different Reynolds number were observed. To maintain Reynolds number and consistent test procedures, the wind tunnel speed and propeller Reynolds numbers was dynamically controlled using a PI controller. The results demonstrated an efficiency dependence on non-dimensional propeller constants including Reynolds number. The propeller diameters ranged from 14 inches to 24 inches with Reynolds numbers of 50,000 to 200,000 at advance ratios from 0 to 1.
