Abstract

On dispose des plans aérodynamiques (24) en anneau, avec leurs parties d'extremité noyées dans des modèles d'anneau de carénage (38) et (34) en cire; on forme un moule (88) en recouvrant ces éléments avec un céramique, puis on retire la cire pour former des cavités de moulage. Celles des anneaux de carénage sont remplies de métal fondu qui se solidifie pour former lesdits anneaux qui relient les plans aérodynamiques. Pour absorber la dilatation thermique de ceux-ci par rapport aux anneaux, on prévoit entre eux un joint à glissement pour la constitution duquel le métal fondu se solidifie dans les cavités sans former de liaisons métallurgiques avec les plans aérodynamiques.
