Title (EN) TURBOPUMP, PARTICULARLY FOR SUPPLYING ROCKET ENGINES WITH GAS
(FR) TURBOPOMPE, EN PARTICULIER POUR L'ALIMENTATION DE MOTEURS DE FUSEE
Abstract: front page image
(EN)The invention relates to the field of turbopumps, and particularly turbopumps for supplying low-thrust rocket engines with gas. A turbopump (301) according to the invention comprises a pump (303), a turbine (304), and a common rotatable shaft (302) connected to said pump (303) and to said turbine (304). A first and second bearing (305, 306), which are nearer to the pump (303) and to the turbine (304), respectively, support the common shaft (302). Said second bearing (306) is a hydrodynamic bearing connected to a gas-supply source, and the turbopump (301) also comprises at least one dynamic seal (311) around the shaft (302), inserted between said first and second bearings (305, 306).
(FR)L'invention concerne le domaine des turbopompes, et en particulier des turbopompes d'alimentation de moteurs-fusées de faible poussée. Une turbopompe (301) selon l'invention comporte une pompe (303), une turbine (304), et un arbre rotatif commun (302) relié à ladite pompe (303) et à ladite turbine (304). Un premier et un deuxième palier (305,306) plus proches, respectivement, de la pompe (303) et de la turbine (304), soutiennent l'arbre commun (302). Ledit deuxième palier (306) est un palier hydrodynamique relié à une source d'alimentation en gaz, et la turbopompe (301) comporte en outre au moins un joint d'étanchéité dynamique (311) autour de l'arbre (302), interposé entre lesdits premier et deuxième paliers (305,306).
