TRANSONIC WATER-JET VESSEL PROPULSOR Russian patent published in 2014 - IPC B63H11/08 B63H11/02 

FIELD: transport.

SUBSTANCE: invention relates to shipbuilding, namely to water-jet propulsors for vessels and other floating crafts. The transonic water-jet vessel propulsor includes inlet and outlet water duct, fluid flow rate booster. The inlet water duct the outlet of which is connected with the inlet of fluid flow rate booster the outlet of which is connected with the inlet of outlet water duct. The fluid flow rate booster includes at least two nozzles on one axis where at least one nozzle is inserted into subsequent nozzle along fluid motion path with creation cavity between them, and at least in all cavities pressure sensors are installed, and in the inlet and outlet nozzles velocity sensors are installed. Herewith, the booster is made with possibility to create water-gas mixture in the area between two adjacent nozzles.

EFFECT: higher coefficient of efficiency, pulse electromagnetic noise elimination.
