 note = {P(論文), 風車の向きが変化する場合とそれが定まっている場合について, 氷片の飛散領域が調べられた。使用された羽根は板羽根である。その形は中心角の小さい扇形か扇の紙形であり, エネルギーを消費する部分が削除されている。先ず, 氷片の運動方程式が求められた。氷片に作用する力は重力と大きさが空気に対する氷片の速さの2乗に比例する抵抗力である。抵抗力を求めるとき, 羽根の後流が考慮されている。次に, 氷片の運動方程式が数値計算によって解かれた。氷片の落下密度と羽根の傾きや風車の高さや氷片の大きさの変化による氷片の飛散領域やその面積の変動が解明された。更に, 氷片の飛散領域の面積と得られるエネルギーとの比が求められている。, For the cases of the rotating axis of the blades varying in all directions and of their rotating axis being fixed in the constant direction, the scatter-domain of the ice = fragment is analytically and numerically studied. A plate-blade is used. It is the shape of a sector or the shape bounded by two circles and one sector with a common center. Those parts of the blade which spend the energy are removed. First of all, the equations of the motion for the ice-fragment are formed by means of analytical calculation. The forces acting on the ice-fragment are the gravity and the resistance against the air, which is proportional to square velocity of the ice-fragment. When the resistance was calculated, the wake of the blade is considered in the calculation. Next, the equations of the motion for the ice-fragment are solved by means of numerical calculation. The variation of the scatter-domain for the tangent of blade, that for the height of the wind-turbine, and that for the size of the ice are obtained. The fall-density of the ice-fragment is also obtained. The area of the scatter-domain of the ice-fragment, which is divided by the energy obtained from the blades, is also investigated.},
