Sharp Corporation has been developing high-performance electric fans by applying the characteristics of wings of living creatures. This paper describes an electric fan having a propeller that mimics the shape of the wings of a Chestnut Tiger butterfly. Most electric fans generate a nonuniformly distributed wind velocity, which cause an uncomfortable feeling for the user. If the number of fan blades was increased, the wind generated would be smoother; however, the efficiency of the propeller itself would decrease. To solve these problems, we have modeled prototype electric fan propeller blades based on the shape of a Chestnut Tiger butterfly wing.
