Abstract

L'invention concerne un dispositif de sécurité destiné à éviter les avaries causées, dans les moteurs à turbine à gaz, par le détachement accidentel des aubes mobiles. Les aubes mobiles 16 sont entourées d'une couronne creuse 21 dont la paroi 22 contiguë aux aubes est assez mince pour qu'une aube ou fragment d'aube détaché la traverse et vienne s'immobiliser dans la couronne. Cette dernière constitue un conduit thermique dont la cavité 23 est remplie d'une vapeur condensable, de préférence de la vapeur de mercure, de façon à améliorer les échanges thermiques et réduire la déformation de la couronne.
