In the case in which (the angular velocity of the blade) (the radius of the blade)/(wind speed) has a value, the range of the gradient of the plate blade, where the wind pressure is plus, is restricted. The wind pressure of which the value is minus is the thrust. By using the wind turbine whose blade gradient can be changed, it is possible to keep the state of the wind turbine for the all values of (the angular velocity of the blade) (the radius of the blade)/(wind speed). In the case in which the blade of the wind turbine is twisted to take out the most energy or to give the maximum value of the efficiency, the wind pressure acting on the blades is naturally plus and these twisted blades show the state of the wind turbine in this condition. The viscosity of the air and the velocity component of the wake in the direction perpendicular to the axis of the rotation of the blades are neglected in this paper.}, pages = {59--64}, title = {風車の羽根の受ける風圧}, volume = {18}, year = {1983}, yomi = {オオカメ, マモル and ワタナベ, オサム and アマザキ, ヒロブミ} }
