FIELD: transport. ^ SUBSTANCE: water-jet propeller has water duct with inlet and outlet orifices and also fluid medium accelerator. Fluid medium accelerator includes at least two nozzles on one axis. At least one nozzle is coaxially introduced into other along fluid medium movement direction with cavity formed between nozzles. At least one cavity communicates with fluid medium supply and suction devices. At least one cavity has fluid medium ionisation means. Cavity with fluid medium supply and suction devices encompasses electrodes for performance of electro-hydraulic impact in fluid medium, electrodes are connected with outlet of block for forming electro-hydraulic impacts in fluid medium. ^ EFFECT: decease of power consumption for vessel propelling, possibility to increase speed and range of sailing, decrease of required fuel stores, and propeller efficiency increase. ^ 2 dwg |
