| Outline of Final Research Achievements |
New VAWT blade that improves starting and rotation performance was developed. Cross section of this blade is comma (Magatama) type. Its performance was evaluated by numerical simulation and wind tunnel test. Maximum output was obtained when this Magatama blade was set between drag and lift type. The performance was further increased when guide banes were equipped. Double blades was also effective to improve the performance. From above results VAWT that can starts rotation in lower speed wind and generates larger power is realized.
