Title (EN) GAS TURBINE ENGINE COOLING STRUCTURE AND METHOD FOR MANUFACTURING SAME
(FR) STRUCTURE DE REFROIDISSEMENT D'UNE TURBINE À GAZ ET SON PROCÉDÉ DE FABRICATION
(JA) ガスタービンエンジンの冷却構造およびその製造方法
Abstract:
(EN) The present invention provides a structure in which an operative gas (A) of a gas turbine engine (GT) is used as a cooling medium (CL) to cool a constituent member of the gas turbine engine, wherein a wall surface (13a) of a flow channel wall (13), which is formed from part of the constituent member and which faces a cooling medium flow channel through which the cooling medium (CL) flows, is provided with recesses (21) formed in the wall surface of the flow channel wall and protrusions (23) formed in at least part of the peripheral edges of the recesses.
(FR) La présente invention concerne une structure dans laquelle un gaz opérationnel (A) d'une turbine à gaz (GT) est utilisé en tant que milieu de refroidissement (CL) pour refroidir un élément constitutif de la turbine à gaz, une surface de paroi (13a) d'une paroi de canal d'écoulement (13), qui est formée à partir d'une partie de l'élément constitutif et qui fait face à un canal d'écoulement de milieu de refroidissement à travers lequel s'écoule le milieu de refroidissement (CL), étant pourvue d'évidements (21) formés dans la surface de paroi de la paroi du canal d'écoulement, ainsi que d'éléments saillants (23) formés dans au moins une partie des bords périphériques des évidements.
(JA) ガスタービンエンジン(GT)の構成部材を、当該ガスタービンエンジンの作動ガス(A)を冷却媒体(CL)として冷却する構造において、前記構成部材の一部から形成された、前記冷却媒体(CL)が流れる冷却媒体流路に面した流路壁(13)の壁面(13a)に、前記流路壁の壁面に形成された凹部(21)と、前記凹部の周縁の少なくとも一部に形成された凸部(23)とを設ける。
