Abstract: front page image
(EN)The disclosed invention relates to a gas turbine disc comprising: a rotor part comprising a plurality of blades and a plurality of discs having the plurality of blades arranged on the outer circumferential surfaces thereof; and a tie bolt passing through a bore part, which is a hollow part of the plurality of discs, thereby coupling the plurality of discs along a central shaft of the rotor part, wherein the diameter of the bore part is greater than the diameter of the tie bolt, and the bore part comprises groove flow channels formed so as to be spaced apart in the circumferential direction of the bore part, wherein the groove flow channels have cooling air flow in the inside spaces thereof by having long grooves formed in the axial direction of the bore part.
(FR)La présente invention concerne un disque de turbine à gaz comprenant : une partie rotor comprenant une pluralité d'aubes et une pluralité de disques ayant la pluralité d'aubes agencées sur leurs surfaces circonférentielles extérieures; et un boulon d'ancrage passant à travers une partie trou, qui est une partie creuse de la pluralité de disques, qui permet d'accoupler la pluralité de disques le long d'un arbre central de la partie rotor, le diamètre de la partie trou étant supérieur au diamètre du boulon d'ancrage, et la partie trou comprend des canaux d'écoulement en rainure formés de manière à être espacés les uns des autres dans la direction circonférentielle de la partie trou, les canaux d'écoulement en rainure ont un flux d'air de refroidissement dans des espaces internes correspondants sous forme de rainures longues formées dans la direction axiale de la partie trou.
