FIELD: engines and pumps. ^ SUBSTANCE: device incorporates water duct arranged in the ship bow bulb housing appliance of converting mechanical energy in hydraulic-jet power representing a set of chambers arranged one above the other in the said water duct lengthwise section and in symmetry with the said duct lengthwise axis. Every chamber incorporates an inlet water-intake hole, the chamber walls forming the nozzles narrowing streamwise and furnished with outlet holes. The proposed device incorporates one central chamber, two external upper and lower chambers and, at least, two internal upper and lower chambers the water duct chamber side walls are formed by the bulb lateral walls. The water duct chamber upper and lower walls represent lengthwise-curvilinear and horizontal-section plates. The central chamber inlet accommodates two concave curvilinear plates arranged in symmetry with the water duct lengthwise axis. The inlet of every internal chamber houses a curvilinear plate concave relative to the water duct lengthwise axis. ^ EFFECT: conversion of ship heaving and pitching energy into hydraulic-jet power, ship stabilisation in storm. ^ 1 dwg |
