Definitions

  • the present invention relates to a propulsion system for ships, of simple constitution, by means of which a higher efficien­cy is achieved.
  • the propulsion systems for ships most commonly used to­day are the propeller systems, which systems have serious disadvan­tages to be obviated by this invention.
  • the object of the present invention is to provide a novel propelling system which is of simple constitution, economical and of high efficiency.
  • blade-runner type hydraulic pumps generally having a small diameter, which are attached at dif­ferent points of the submerged periphery of the ship's hull.
  • These pumps are propelled by means of hydraulic, pneumatic, explosion or turbine engines, or a combination of these, and the corresponding transmission thereof.
  • the pumps are provided with a casing or deflector which allows the water to be sucked, through a tangential opening and along the runner, from the front zone.
  • the water may also be sucked from the front zone, through the ends of the runners, by means of tubular elbows towards the inside of the drum or hollow shaft of the runner.
  • the shafts of the runners of the pumps are disposed perpendicularly to the longitudinal axis of the ship and para­llel to the hull wall.
  • the most important advantages thereof are: It is useful for all kinds of ships, including sub­marines. A higher development of the propelling power. It may be attached at different submerged points of the hull and, therefore, the size thereof does not necessarily have to be excessive. It is easy to repair or replace a runner or blade without having to stop the ship, and it is more protected than the propeller.
  • the zones at which they adapt themselves are not eddy zones. They may be incorporated to already constructed ships. They hardly have leakages due to the transmission. Sealing gaskets are not so necessary.
  • the hydrodynamic spray moves parallel to the surface of the ship and to its longitudinal axis. It operates easily, inverting the stream of water. It is cheaper than the other systems. It may reach higher speeds. Eddies are not produced.
  • Figures 3, 4 and 5 show a prolongation or deflector 16, of the cylindrical casing embedded in the hull of the ship, which improves its efficiency.
  • centrifugal blade runners enables mat­erials, such as stainless steel and others, which are hardly af­fected by cavitation to be used.
