Title (EN) GAS TURBINE BLADE
(FR) AUBE DE TURBINE À GAZ
(KO) 가스터빈 블레이드
Abstract: front page image
(EN) Disclosed is a gas turbine blade. A gas turbine blade according to an embodiment of the present invention comprises: a plurality of guide ribs spaced from each other along a movement direction of a cooling fluid, which flows along a cooling fluid channel formed inside a turbine blade, in order to guide a movement of the cooling fluid; and an opening formed in front of the guide ribs to allow a part of the cooling fluid to be supplied to a first heat conduction area in which heat conduction is relatively degraded at bottom surfaces of the cooling fluid channel or at side walls adjacent to the bottom surfaces, wherein each of the bottom surfaces corresponds to a segment between the guide ribs.
(FR) L'invention concerne une aube de turbine à gaz. Une aube de turbine à gaz selon ce mode de réalisation de la présente invention comprend : une pluralité de nervures de guidage espacées les unes des autres le long d'une direction de déplacement d'un fluide de refroidissement, qui s'écoule le long d'un canal de fluide de refroidissement formé à l'intérieur d'une aube de turbine, afin de guider un mouvement du fluide de refroidissement; et une ouverture formée devant les nervures de guidage pour permettre à une partie du fluide de refroidissement d'être fournie à une première zone de conduction de chaleur dans laquelle la conduction de chaleur est relativement dégradée au niveau des surfaces inférieures du canal de fluide de refroidissement ou sur des parois latérales adjacentes aux surfaces inférieures, chacune des surfaces inférieures correspondant à un segment entre les nervures de guidage.
(KO) 가스터빈 블레이드가 개시된다. 본 발명의 일 실시 예에 의한 가스터빈 블레이드는 터빈 블레이드 내부에 형성된 냉각 유로를 따라 유동하는 냉각유체의 이동을 가이드 하기 위해 상기 냉각유체의 이동 방향을 따라 다수개가 서로 간에 이격된 가이드 리브; 및 상기 가이드 리브들 사이의 구간에 해당되는 냉각 유로의 바닥면 또는 상기 바닥면과 이웃한 측벽에서의 열전도가 상대적으로 저하되는 제1 열전도 영역으로 상기 냉각유체 중의 일부가 공급되도록 상기 가이드 리브의 정면에 형성된 개구부를 포함한다.
