Title (EN) METHOD OF MANUFACTURING A COMPONENT
(FR) PROCÉDÉ DE FABRICATION D'UN COMPOSANT
Abstract:
(EN) A method of manufacturing a component (100) for a turbo machine. The component (100) comprises a main body (104) having a fluid inlet (103) and fluid outlet (200). A cooling passage (204) extends between a fluid inlet (103) and a fluid outlet (200). The cooling passage (204) is divided into a first (204A) and a second section (204B) which extend between the fluid inlet (103) and fluid outlet (200). The first section (204A) has a first predetermined roughness; and the second section (204B) has a second predetermined surface roughness; the predetermined surface roughness in at least one of the first section (204A) and second section (204B) is defined by a plurality of spaced apart micro ribs (212) which extend at least part of the way across the cooling passage (204), at least one of the cooling passage sections is formed to further comprise macro ribs (206) which extend across the cooling passage (204), at least one micro rib is being formed between adjacent macro ribs (206).
(FR) L'invention concerne un procédé de fabrication d'un composant (100) pour une turbomachine. Le composant (100) comprend un corps principal (104) ayant une entrée de fluide (103) et une sortie de fluide (200). Un passage de refroidissement (204) s'étend entre l'entrée de fluide (103) et la sortie de fluide (200). Le passage de refroidissement (204) est divisé en une première (204A) et une seconde section (204B) qui s'étendent entre l'entrée de fluide (103) et la sortie de fluide (200). La première section (204A) a une première rugosité de surface prédéterminée; et la seconde section (204B) a une seconde rugosité de surface prédéterminée. La rugosité de surface prédéterminée dans au moins l'une de la première section (204A) et de la seconde section (204B) est définie par une pluralité de micro-nervures espacées (212) qui s'étendent au moins en partie à travers le passage de refroidissement (204), au moins l'une des sections de passage de refroidissement étant formée pour comprendre en outre des macro-nervures (206) qui s'étendent à travers le passage de refroidissement (204), au moins une micro-nervure étant formée entre des macro-nervures adjacentes (206)
