Title
(EN) STRUCTURAL GUIDE VANE SONIC SHAPE AND INSPECTION
(FR) INSPECTION ET FORME ACOUSTIQUES D'AUBE DIRECTRICE STRUCTURELLE
Abstract
(EN)
A method of forming a guide vane is disclosed. The method includes forming a vane blank with sufficient material to fabricate the guide vane in accordance with any one of a plurality of different vane classes. The vane blank is inspected for material inconsistencies, and material is removed from the vane blank to form a desired guide vane in accordance with one of the plurality of vane classes. The inspection process includes disregarding at least one material inconsistency in a region of the vane blank that is removed to form the guide vane.
(FR)
La présente invention se rapporte à un procédé de fabrication d'une aube directrice. Le procédé consiste à former une ébauche d'aube avec suffisamment de matériau pour fabriquer l'aube directrice selon l'une quelconque d'une pluralité de différentes classes d'aube. L'ébauche d'aube est inspectée pour détecter des incohérences matérielles et le matériau est éliminé de l'ébauche d'aube afin de former une aube directrice souhaitée selon l'une des classes d'aube de la pluralité de classes d'aube. Le procédé d'inspection consiste à ignorer au moins une incohérence matérielle dans une région de l'ébauche d'aube qui est enlevée afin de former l'aube directrice.
