 note = {P(論文), For each value of (the angular velocity of the blade) (the radius of the blade)/(the wind speed), there is one twist of the blade which takes out the most energy. The value of (the angular velocity of the blade) (the radius of the blade)/(the wind speed) changes so often, that we can not always take the most energy out of the only one of these twisted blades. However, it is possible to take out more energy by rotating the blades at the joint. These relations were investigated from the results of the numerical calculation. In this paper the shape of the blade is a sector with a small central angle, and the air viscosity and the velocity component of the wake in the direction perpendicular to the rotation axis of the blades are neglected.},
