FIELD: transport; shipbuilding.
SUBSTANCE: water-jet propeller for submarine vessel contains at least one liquid flow accelerator in propeller nozzle coaxial with stern extremity of vessel and includes at least two nozzles on same axle. At least one nozzle is coaxially introduced into next nozzle in direction of fluid movement with formation of cavity in between nozzles. At that, at least one cavity is communicated with fluid supply and suction devices. At least in one cavity with fluid supply and suction devices liquid media ionisation means are located. All cavities are supplied with pressure gauges and inlet and outlet jet nozzles have speed sensors. Cavities with fluid supply and suction devices have electrodes installed for electrohydraulic impacts in liquid media.
EFFECT: significant decrease of hydrocarbon fuel consumption, decrease of hydraulic resistance, enhancement of water-jet propeller efficiency.
