Abstract
Presented is a way to reduce the wave drag of high speed ships by ingesting wave energy into water propulsors disposed at the bow and/or on the sides of the main hull of the ship. A forward secondary bow disposed at a lower portion of the main bow of the ship is an optimum location to have bow water propulsor water inlets. Performance of the water propulsors can be enhanced by using Coanda effect water energizers at the inlets to the water propulsors. Water propulsor discharge is preferably into an air layer on the underside of the ship's main hull.
Claims22
In an improved means for integrating a water propulsion system into a ship, the improvement comprising:
- a secondary bow disposed, at least in its majority, proximal a lower forward portion of a main bow of the ship, a bow oriented water propulsor having a first bow oriented ram water inlet disposed proximal a forward portion of a secondary bow of a main hull of the ship and said bow oriented ram water inlet, at least in its majority, defining an opening in a forward portion of the secondary bow of the ship to take in water directly approaching the secondary bow of the ship and wherein, when the ship is moving forward and the first bow oriented water propulsor is operating, water taken into the first bow oriented ram water inlet generates a hydrodynamic force on a bow wave of said ship thereby reducing energy of said bow wave.
In an improved means for integrating a water propulsion system into a ship, the improvement comprising:
- a secondary bow disposed, at least in its majority, proximal a lower forward portion of a main bow of the ship and including a secondary bow upper surface propulsor water inlet and wherein said secondary bow upper surface propulsor water inlet takes in water flowing over the secondary bow of the ship and supplies said water to a water propulsor and wherein, when the ship is moving forward and the water propulsor is operating and producing forward thrust, water taken into the secondary bow upper surface propulsor water inlet generates a hydrodynamic force on a bow wave of said ship thereby reducing energy of said bow wave.
In an improved means for integrating a water propulsion system into a ship, the improvement comprising:
- a secondary bow disposed, at least in its majority, proximal a lower portion of a main bow of the ship and including a Coanda effect fluid energizer disposed proximal a forward portion of said secondary bow wherein said Coanda effect fluid energizer energizes water supplied to a propulsor water inlet and wherein said water inlet supplies water to a water propulsor and wherein, when the ship is moving forward and the water propulsor is operating and generating forward thrust, water taken into the propulsor water inlet generates a hydrodynamic force on a bow wave of said ship thereby reducing energy of said bow wave.
In an improved means for integrating a water propulsion system into a ship, the improvement comprising:
- a secondary bow disposed, at least in its majority, proximal a lower forward portion of a main bow of the ship and including a secondary bow upper surface propulsor water inlet and a Coanda effect fluid energizing means disposed forward of said secondary bow upper surface propulsor water inlet to thereby energize water taken into the secondary bow upper surface propulsor water inlet and wherein said secondary bow upper surface propulsor water inlet takes in water flowing over the secondary bow of the ship and supplies such water to a water propulsor and wherein, when the ship is moving forward and the water propulsor is operating and producing forward thrust, water taken into the secondary bow upper surface propulsor water inlet generates a hydrodynamic force on a bow wave of said ship thereby reducing energy of said bow wave.
In an improved means for integrating a water propulsion system into a ship, the improvement comprising:
- a first propulsor water inlet disposed in a side of the main hull of the ship proximal a forward knuckle in the side of the main hull of the ship and a Coanda effect fluid energizing device disposed proximal said first propulsor water inlet, and a second propulsor water inlet disposed in the side of the main hull of the ship and forward of an aft portion of the main hull of the ship and a Coanda effect fluid energizing device disposed proximal said second propulsor water inlet and wherein said water inlets are supplied with water energized by the Coanda effect fluid energizing means.
