Title (EN) EYEBALL SEALS FOR GIMBALED ROCKET ENGINES, AND ASSOCIATED SYSTEMS AND MTEHODS
(FR) JOINTS À ROTULE POUR DES MOTEURS-FUSÉES MONTÉS À LA CARDAN ET SYSTÈMES ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) Eyeball seals for a gimbaled rocket engines, and associated systems and methods are disclosed. A system in accordance with a particular embodiment includes a rocket body, an engine carried by and movable relative to the rocket body, and a seal assembly. The seal assembly can include a sealing surface carried by one of the rocket body and the engine, and a seal element carried by the other of the rocket body and the engine. The seal element is in contact with the sealing surface. The seal assembly can further include a cylinder and a piston slideably received in the cylinder, with one of the piston and the cylinder carrying the seal element. The cylinder includes ports that are in fluid communication with a region external to the rocket body. Accordingly, pressures external to the rocket body can force the seal element and/or the sealing surface into contact with each other.
(FR) L'invention concerne des joints à rotule pour des moteurs-fusées montés à la Cardan et des systèmes et procédés associés. Un système selon un mode de réalisation particulier comprend un corps de fusée, un moteur contenu dans le corps de fusée et mobile par rapport à celui-ci et un ensemble joint. L'ensemble joint peut comprendre une surface d'étanchéification contenue dans un élément parmi le corps de fusée et le moteur et un élément joint contenu dans l'autre élément parmi le corps de fusée et le moteur. L'élément joint est en contact avec la surface d'étanchéification. L'ensemble joint peut comprendre en outre un cylindre et un piston reçu de manière coulissante dans le cylindre, le piston et/ou le cylindre contenant l'élément joint. Le cylindre comprend des orifices qui sont en communication fluidique avec une zone externe au corps de fusée. Par conséquent, des pressions externes au corps de fusée peuvent forcer l'élément joint et/ou la surface d'étanchéification à venir en contact l'un avec l'autre.
