Abstract (en)
The method involves defining an angular distribution pattern of units of a stator (10) on a predetermined angular sector. The pattern is repeated on entire circumference of the stator so that temperature is distributed symmetrically on entire circumference of a casing (12) of the stator. A set of angular sectors of a case (24) is placed around the casing, to discharge air from the casing. The pattern is defined to avoid radial alignment between inter-spacer zones (14a), defined between two adjacent spacers (14), and inter-sector zones (24a) defined between two adjacent sectors of the case (24). An independent claim is also included for a stator of a high-pressure turbine of a turbomachine.

Procédé d'assemblage d'éléments sectorisés (14, 24) d'un stator annulaire (10) d'une turbine haute-pression de turbomachine autour d'un axe longitudinal (X-X) de ladite turbine, procédé selon lequel, on définit un motif de répartition angulaire des éléments du stator pour un secteur angulaire prédéterminé (Ψ), le motif de répartition étant défini de façon à éviter un alignement radial entre des zones inter-secteurs (14a, 24a) des éléments du stator (14, 24) définies entre deux secteurs adjacents d'un même élément du stator, et à répéter ledit motif de répartition sur toute la circonférence du stator. <IMAGE>
