The invention concerns a ship low-noise hydrojet propeller unit with good performance. It mainly comprises a hydrojet propeller assembly consisting of a hydraulic screw (7) feeding a helico-axial pump (8) emerging in the diffusers (9). A nozzle (10) completes the assembly, which is powered by lateral louvers (6). The electric motor (11R, 11S) is axially represented, but may be radial. The shaft (3) is rotatably mounted, through hydraulic thrust bearings (4V, 4R). The assembly can be have azimuthal orientation. The invention is applicable to ships and submarines.
Le propulseur de navire par hydrojet immergé est peu bruyant et présente un bon rendement.Il comprend principalement un ensemble de propulsion par hydrojet constitué d'une vis hydraulique (7) alimentant une pompe hélico- axiale (8) débouchant dans des redresseurs (9). Une tuyère (10) termine l'ensemble, qui est alimenté par des ouïes latérales (6). Le moteur électrique (11R, 11S) est représenté axial, mais peut être radial. L'arbre (3) est monté rotatif, grâce ô des paliers-butées (4V, 4R) hydrauliques. L'ensemble peut être orienté en azimut.Application ô la propulsion des navires et des sous- marins.
