Title (EN) ROTOR BLADE AND HORIZONTAL WATER TURBINE COMPRISING SAME
(FR) PALE DE ROTOR ET TURBINE HYDRAULIQUE HORIZONTALE ÉQUIPÉE DE LADITE PALE
(JA) ロータブレードとこれを備える横軸水車
Abstract:
(EN) Provided is a rotor blade that is configured so as to gather a fluid from both a blade root and a blade end of a blade toward the center along the length direction of the blade, allow a large quantity of the fluid to pass toward the trailing-edge direction, and raise rotation efficiency through a reaction to the passage of the fluid. In a front view, the chord length is gradually increased from the blade root 2 toward the blade end, and with a maximum-chord-length section 4 as a reference point, the blade end serves as a forward-inclined part 6 that is inclined forward, and a surface that is flat in the chord direction is inclined toward a rear surface from a leading edge 7 to a trailing edge 8. In a side view, the thickness is gradually increased from a main section 5 to the distal-end part of the blade root 2 to form a thick-base section.
(FR) L'invention concerne une pale de rotor qui est conçue pour collecter un fluide provenant d'une racine de pale et d'une extrémité de pale d'une pale vers le centre dans la direction de la longueur de la pale, permettre à une grande quantité du fluide de passer en direction du bord de fuite et augmenter l'efficacité de rotation par l'intermédiaire d'une réaction au passage du fluide. En vue de face, la longueur de corde est progressivement augmentée depuis la racine de pale (2) vers l'extrémité de pale, et avec une section de longueur de corde maximale (4) en tant que point de référence, l'extrémité de pale sert de partie inclinée vers l'avant (6) qui est inclinée vers l'avant, et une surface qui est plate dans la direction de corde est inclinée vers une surface arrière depuis un bord d'attaque (7) jusqu'à un bord de fuite (8). En vue de côté, l'épaisseur est progressivement augmentée depuis une section principale (5) vers la partie d'extrémité distale de la racine de pale (2) pour former une section de base épaisse.
(JA) ブレードの翼根及び翼端の両方向から、ブレードの長さの中間方向へ流体を集合させて、後縁方向へ多量の流体を通過させ、その反作用により回転効率を高めるようにした、ロータブレードを提供する。 正面視で翼根2から翼端方向へ次第に弦長を大とし、最大弦長部4を基点として、翼端を前向傾斜とした前向傾斜部6とし、弦方向に平坦な前面を、前縁7から後縁8へかけて後面寄りに傾斜させるとともに、側面視で主部5から翼根2の基端部へかけて次第に厚くして厚基部としてある。
