Title
(EN) ROTOR BLADE AND DISC OF ROTATING BODY
(FR) PALE DE ROTOR ET DISQUE D'UN CORPS ROTATIF
(JA) 回転体の動翼およびディスク
Abstract
(EN)
A rotor blade (15) embedded in a disc (17) of a rotating body (1) wherein, in a transverse section, a blade root (21) of the rotor blade has at least one stage of protruding parts (23), which protrude on both sides in a direction that includes a circumferential component, and are for engaging the blade root (21) with the disc (17). A contact surface (23a) of the protruding parts (23) that is in contact with the disc (17) slants toward a center portion of the blade root (21) so as to extend from the radially inward side toward the radially outward side, and a noncontact surface (23b) of the protruding parts (23) that is not in contact with the disc (17) slants toward the center portion of the blade root (21) so as to extend from the radially inward side toward the radially outward side.
(FR)
La présente invention concerne une pale de rotor (15) intégrée dans un disque (17) d'un corps rotatif (1); dans une section transversale, une emplanture de pale (21) de la pale de rotor comporte au moins un étage de parties en saillie (23), qui font saillie des deux côtés dans une direction qui comprend un composant circonférentiel et qui sont destinées à venir en prise avec l'emplanture de pale (21) avec le disque (17). Une surface de contact (23a) des parties en saillie (23) qui est en contact avec le disque (17) s'incline vers une partie centrale de l'emplanture de pale (21) de sorte à s'étendre depuis le côté radialement vers l'intérieur vers le côté radialement vers l'extérieur, et une surface sans contact (23b) des parties en saillie (23) qui n'est pas en contact avec le disque (17) s'incline vers la partie centrale de l'emplanture de pale (21) de sorte à s'étendre depuis le côté radialement vers l'intérieur vers le côté radialement vers l'extérieur.

回転体(1)のディスク(17)に植設される動翼(15)において、当該動翼の翼根(21)が、横断面形状において、当該翼根(21)をディスク(17)に係止するための、周方向成分を含む方向の両側に突出する突出部(23)を少なくとも1段有し、前記突出部(23)の、ディスク(17)に接触する接触面(23a)が、当該翼根(21)の中央部に向かうに従って径方向内側から径方向外側に延びるように傾斜しており、前記突出部(23)の、ディスク(17)に接触しない非接触面(23b)が、当該翼根(21)の中央部に向かうに従って径方向内側から径方向外側に延びるように傾斜している。
