HYDROJET DEVICE FOR CONVERSION OF MECHANICAL ENERGY OF SHIP'S OSCILLATING MOTION TO HYDROJET ENERGY Russian patent published in 2014 - IPC F03B13/14 B63B39/08 

FIELD: power industry.

SUBSTANCE: hydrojet device includes a water passage with nozzles formed with vertical side walls and flat plates. The water passage is divided at least into two cascades. Each successive cascade has bigger height. Cascades are connected to each other by means of connection planks. Each cascade of the water passage has upper and lower outside channels, at least one upper inner nozzle, one lower inner nozzle and one central nozzle. An inlet water intake hole of the central nozzle is located vertically and perpendicular to the longitudinal axis of the water passage. Connection planks are inclined to the longitudinal axis of the water passage in a vertical plane. The water passage diverges along the longitudinal axis of the water passage in a horizontal plane. Flat plates are bent symmetrically and in a convex manner relative to the longitudinal axis of the water passage in a horizontal plane so that a blunt angle is formed. Water flow turbulisers formed with spiral-shaped vertical strips are installed on the outer side of the side walls of the water passage.

EFFECT: improving use efficiency of a hydrojet device at conversion of oscillating motion energy of a ship to hydrojet energy.
