The cycloidal propeller is a propulsion system which can derive thrust in omni-direction by changing the attack angle of wing rotating with a constant speed. In order to investigate the characteristics of the cycloidal propeller, it is analyzed with Vortex method in this study. The motion of the propeller can be described as combination of in-phase pitching and heaving oscillation. Results of quasi-steady and unsteady analyses are shown in the vector diagrams. Unsteady flow effect by wake vortices is inferred by comparing both results. Calculated results of the average of wind velocity and direction confirm the necessity of the unsteady flow analysis, and it can be explained by the distribution of vortices.
