HYDRAULIC PROPULSION DEVICE OF BLADE PUMP TYPE AND VESSEL EQUIPPED WITH SUCH A DEVICE Russian patent published in 2022 - IPC B63H5/14 

FIELD: shipbuilding.

SUBSTANCE: invention relates to the shipbuilding, namely to a hydraulic propulsion device of a blade pump type, designed, in particular, for vessels. The hydraulic propulsor contains a hollow outer case, a hydraulic rotor, two stators located in the hollow case from each side of coupling and blades of the hydraulic rotor, which are a front stator located upstream at the forward course of the vessel, and downstream at the reverse course of the vessel, respectively, and a rear stator located downstream at the forward course of the vessel, and upstream at the reverse course of the vessel. Each stator contains at least two immobile radial supports for the maintenance of the hydraulic rotor inside the hollow case, made profiled to form plates. At least two rotary flaps are located relatively to blades of the hydraulic rotor, passing along edges of two immobile radial supports, and mounted with the possibility of control of their rotation. At the forward course of the vessel, flaps of the front stator are oriented in the direction of blades of a rotor screw at an angle closer to an angle of the driving edge. At the reverse course of the vessel, flaps of the front stator are oriented in the direction of blades of the rotor screw at an angle of orientation, closer to the angle of the driving edge. Flaps of the rear stator are oriented in the direction of blades of the rotor screw at an angle of orientation, closer to a visible angle of incidence of driven edges of the specified blades.

EFFECT: durability of this hydraulic propulsor is achieved.
