AUXILIARY HYDROJET DEVICE Russian patent published in 2009 - IPC F03B13/14 B63B39/08 

FIELD: engineering industry.

SUBSTANCE: invention refers to wave energy conversion devices and is meant for converting ship's vibration energy into hydrojet energy. Device includes a water conduit provided in bow bulb of the ship. Therein arranged is device meant for conversion of mechanical energy into hydrojet one. That device is made in the form of chambers. Chambers are located one above the other in a vertical longitudinal plane of water conduit section and symmetrically relative to its longitudinal axis. Each chamber is provided with an inlet water-intake opening. Walls of chambers form nozzles with outlet openings, which narrow in the flow direction. Hydrojet energy of water jet at the ship's going ahead can compensate some part of lost speed. In order to stabilise ship's position at strong side wind, on each side wall of bulb on its external side there provided is a vertical chamber with an inlet opening from the side of bulb front. Nozzles provided in the flow direction forward the outgoing flow to the sides from external side wall of the bulb, thus creating jet reaction in the direction opposite to direction of ship's transfer. After each vertical chamber in side wall of the bulb there provided are outlet openings of water conduit.

EFFECT: converting ship's vibration energy into hydrojet energy.
