type:Article

In recent years, electric ducted fan (EDF) has been applied to propulsion unit for small aircrafts. EDF is a small axial flow fan with longer casing, thinner blades and higher rotating speed than conventional small axial flow fan used for cooling in electronic device. In the study, a 1/10 size small EDF of the actual propulsion unit was used and effects of design factors of impeller such as number of blades, blade shape and tip clearance on thrust and noise characteristics were investigated. As a result, in the performance viewpoint, reducing blade thickness, reducing solidity and equalizing tip clearance contributed to performance improvement. In the viewpoint of noise reduction, the first-order blade passing frequency noise was dominated by non-uniform tip clearance due to eccentricity and deformation of impeller. In terms of tip clearance, noise was reduced by equalizing tip clearance. Total performance of EDF was evaluated by specific noise level which was defined by this study.
