Abstract

The invention is Hull Suspension Technology (HST), a specific technology which incorporates mechanics and hydrodynamics to allow the bottom rear part of the vessel hull to fluctuate up and down to counter water surface and stabilize vessel movement while the vessel is in operation. HST also utilizes hinges to mount the stern and bow hulls together efficiently, and implements shock absorbers in its design, which dampen the impact of outside factors and streamline the overall movement of the vessel during operations.

Description

  • This application is cross-referenced to provisional utility patent No. 60/486872 filed on Jul. 11, 20003. This invention obtained no research or development aid through federal sponsorship.
    • BACKGROUND OF INVENTION
  • This invention pertains to marine vessel hydrodynamic technology. The invention focuses on hull technology, performance, and comfort of vessels of all sizes.
  • Currently vessel performance faces limitations that cannot be overcome with traditional hull technology:
      • Sea surface condition changes (waves and sea depressions)
      • Engine continues to push the vessel out of the water as the hull generates lift due to speed, which causes the vessel to move up and down in an inefficient manner
      • Short engine life due to excessive variation in torque demand
      • High fuel consumption due to performance inefficiency
      • Short vessel life due to vibration and water surface impacts, resulting in hull cracks and metal fatigue
      • Vessel turning control is limited due to the fact that current hulls slide inefficiently across the water surface in high-speed turns
    BRIEF SUMMARY OF THE INVENTION
  • Hull Suspension Technology (HST) modifies the hull of a vessel to act as a shock absorbing system.
  • HST is a system that allows the stem of the hull (last 30%) to move upwards to counter the ocean surface movement when the vessel is moving at speed.
  • The hull is made of two major components: first, the bow hull that is about 70% of the vessel; and second, the power plant hull, or the stem, that makes up the remaining 30% of the vessel.

    • DETAILED DESCRIPTION OF THE INVENTION
  • Hull Suspension Technology modifies the hull of a vessel to act as a shock-absorbing system.
  • HST is a system that allows the stem of the hull (last 30%) to move upwards to counter the ocean surface movement when the vessel is moving at speed (please see Drawing 1).
  • The hull is made of two major components: first, the bow hull that is about 70% of the vessel; second, the power plant hull or the stem that takes up the remaining 30% of the vessel (please see Drawings 1 and 2).
  • Both hulls are completely independent and watertight; power plant support and control comes through flexible hoses and connectors (please see Drawings 2 and 3).
  • The two hulls are connected at the bottom via dual hinges and connect at the top via dual shock absorbers. These connections will allow the stem hull to flex upwards in a semi-circular motion to counter ocean surface movements and engine torque (please see drawings 3, 4, and 8).
  • The two main hinges are the main mounting points between the two hulls; the hinges are made of aluminum alloy for strength and light weight; carbon steel can be used for large vessels.
  • Due to the large diameter of the hinges, the hinges will require minimum maintenance and will show very limited wear after long-term usage.
  • The hinges are limited in range based on the vessel size and type.
  • The bow hull overlaps the stem hull from the top and the sides, therefore the vessel will appear similar to any non-HST vessel above the waterline (please see Drawings 1-4).
  • Main hinges are made of 1.5 cm thick steel for vessels 22′-36′ long; they include ball bearings and a rubber cover for protection from sea corrosion (please see Drawing 8).
  • Bow hull overlaps the stem hull from the bottom by about 80 mm for vessels between 22′ and 36′; this will allow for smooth travel in the water.
  • Overlap flap covers the gap between the bow hull and the stem hull at the bottom for a seamless hydrodynamic effect on the vessel movement; it mounts to the bow hull. The overlap flap is made of flexible lightweight plastic to enhance the hydrodynamics of the hull.
    • ASSEMBLY OF THE INVENTION
  • Assembling the bow and stem hull together requires the following steps:
  • 1—Finish the Pre-Assembly preparation process
  • 2—From the back of the boat, move the stem hull forward until it reaches the bow hull
  • 3—Lift the stem hull upwards until the hinges mate
  • 4—Insert the hinge pins from the inside of the hull to the outside
  • 5—Tighten the nuts on the pins
  • 6—Secure the shocks to the stem hull and tighten the nuts
  • 7—Plug in the two main electrical connectors
  • 8—If fuel tanks are external connect the fuel lines
  • 9—Connect the air intake extension hose
  • 10—Connect A/C hoses if available
  • 11—Connect hydraulic hoses for the SAU optional electronically-controlled units
  • 12—Test the hinge mount nuts for fastening pressure
  • 13—Lock the hinge boot in place and fill with lubricant
  • 14—Insure that the shock absorber is tightened to the proper pressure
  • 15—Lubricate the shock absorber rod
  • 16—Lock the shock boot in place (do not fill with lubricant)
  • 17—Install the overlap flap in place
  • 18—Seal the overlap flap screw holes
    • PURPOSE OF HST
  • Revolutionary ride comfort and smoothness
  • Minimize structure stress on the hull
  • Minimize the engine noise
  • Minimize ocean surface impact noise
  • Increase performance
  • Stabilize velocity on open water
  • Improve all kinds of vessels, including super-large vessels
