Abstract

Napęd strumieniowy jednostki pływającej z co najmniej jednym strumieniowym pędnikiem azymutalnym, osadzonym na dnie jednostki pływającej, charakteryzuje się tym, że jego pędnik ma postać diagonalnej pompy wodnej (9) o odwróconym kierunku przepływu wody, przy czym kadłub (10) pompy ma w swej górnej części kanał zalewowy (19), napełniany grawitacyjnie wodą z otoczenia jednostki pływającej, a osiowo ukierunkowany kanał tłoczny (22) z umieszczonym wewnątrz niego wirnikiem diagonalnym (11) ma swój wylot (23) w dolnej części kadłuba (10) pompy, natomiast dolna, obrotowo nastawna ściana (24) kadłuba (10) ma otwór (25), w którym jest osadzona dysza wylotowa (26), wyposażona w pochyłe łopatki kierujące (27).Jet propulsion of a watercraft with at least one azimuth jet propeller, mounted on the bottom of a watercraft, is characterized in that its propeller is a diagonal water pump (9) with reversed water flow direction, with the pump casing (10) in its upper parts: the flood channel (19), gravity filled with water from the surrounding of the vessel, and the axially oriented discharge channel (22) with a diagonal rotor (11) located inside it has its outlet (23) in the lower part of the pump casing (10), while the lower one, the rotatably adjustable wall (24) of the fuselage (10) has an opening (25) in which the discharge nozzle (26) is mounted, equipped with inclined steering blades (27).
