@@@@This paper introduce the basic principle and machine construction of cycloidal propeller .To fur‐ther understand the aerodynamic performance of cycloidal propeller ,this paper also analyze the aerodynam‐ic mechanics of lift generation and the aerodynamic interaction of propeller's blades both by semi‐steady as‐sumption theory and unsteady overset grid CFD simulations .On the basis of above analysis ,possible ap‐plications of cycloidal propeller on airship or aerostat are prospected .
