2526 クロスフロー型風車における翼枚数および翼取付角が出力特性に及ぼす影響(S47-4 自然の流体エネルギー利用技衛(風車2),S47 自然の流体エネルギー利用技術)  [in Japanese] 2526 Influence of the Number and Setting Angle of Blade on a Cross-flow Wind Turbine Performance  [in Japanese]

A cross-flow wind turbine is driven by mainly drag force on its blades. For the performance of a cross-flow wind turbine, the number of blades and blade setting angle are important design parameters. So, we studied influences of these factors on the performance of the wind turbine by changing the number of blades and blade setting angle variously. 6, 8, 10, 12 and 16 blades of 5 cases for the number of blades and 30, 45, 60 and 90 degree of 4 cases for the blade setting angle were tested. 12 blade case and 45 degree blade setting angle case showed the almost highest performance coefficient and stable performance characteristic.
