SHIPBOARD ELECTROHYDRAULIC PROPELLER Russian patent published in 1994 - IPC

FIELD: sgipbuilding. SUBSTANCE: shipboard electrohydraulic propeller cosists of hull 1 of flat-bottomed vessel whosel bottom 3 has wavy surface 4 with grooves 5. Electrodes 7 and 9 are mounted in the walls and in the top of grooves 5 by means of dielectric plugs 6 and 10. Electrodes 7 and 9 are connected with shipboard power supply source by means of thyristor control circuit. When power is fed to dishargers 7, are effected in grooves 5 which are accompanied by exhaust of reactive jets of water from grooves 5 at preset angle, thus achieving the aim of innovation, since form simultaneously the lift force and thrust of the ship in preset direction as components of jet reaction. EFFECT: extended functional capabilities of propeller. 5 dwg
