Abstract
The hydrojet boat submerged propulsions system is low noise and has good output. It comprises principally a hydrojet propulsion system comprised of a hydraulic screw (7) feeding a helico-axial pump (8) emerging through downstream guide vanes (9). A nozzle (10) completes the assembly, which is supplied by lateral intakes (6). The electrical motor (11R, 11S) is represented axially, but can also be radial. The shaft (3) is rotationally mounted by means of hydraulic thrust bearings (4V, 4R). The system can be oriented in azimuth. Application in ship and submarine propulsion.
