Abstract

L'ensemble moteur-fusée à liquides comprend une chambre de poussée (440), une tuyère (430) et une structure de joint (410). La structure de joint (410) attache la chambre de poussée (440) et la tuyère (430) et comprend au moins un élément d'étanchéité et une bague d'attache (105) interposée entre la chambre de poussée (440) et la tuyère (430). Des pièces de fixation (420) s'étendent entre la tuyère (430) et la chambre de poussée (440) à travers l'au moins un élément d'étanchéité (100) et la bague d'attache (105). Les matériaux de la chambre de poussée (440) et de la tuyère (430) présentent des coefficients de dilatation thermique différents.
