Abstract

Un segment de joint radial (24) comporte un barrage d'air radial (42). Le barrage d'air radial (42) comporte au moins un générateur de rideau d'air (44) prévu le long d'un diamètre interne du barrage d'air radial (42). Le segment de joint radial (24) peut comporter une ou plusieurs caractéristiques hydrodynamiques (40). Le segment de joint radial (24) peut comporter une pluralité de rainures de barrage d'air radial (46). Un ensemble d'étanchéité (20) peut comporter ce type de segments de joint radial (24).
