Abstract

Une tuyère (11) d’une turbomachine à double flux comprend, à la jonction entre la veine secondaire et une cavité (12) de ventilation d’un stator intermédiaire (4) séparant la veine primaire (5) de la veine secondaire (6), un volet (18) mobile réuni au stator par une liaison rigide mais fusible, et une liaison souple (19). En cas d’élévation de débit et de pression dans la cavité (12), la liaison fusible se rompt, et le volet (18) se déplace pour élargir l’ouverture (15) d’évacuation de la cavité (12). Figure pour l’abrégé : Figure 3.
