Abstract

The Invention provides a method of reducing friction and water pressure when an ocean going Vessel moves trough water by a device consisting of a sub-water container that is supplied and continuously pressurized with air that is then released through outlets at the top of the container, thus creating a mixture of air and water that provides less friction and pressure to the bow of the Vessel, resulting in greater speed and less fuel consumption.

Description

    BACKGROUND OF THE INVENTION
  • The invention relates to means and methods of reducing friction and water pressure to a vessel moving through water.
  • Since the power required are approximately squared*, in order to double the speed of a vessel moving through water. This device will reduce the factors involved in resisting a vessel's motion through water.
    *it takes four times the power
    • DESCRIPTION OF DRAWING
  • The above object, together with its described features of the invention, will be apparent in light of details of construction and use of the “Pneumatic-Aquatic”, Friction and water pressure reducing device.
  • FIG. 1 in the drawing shows a side elevation view of the device.
  • FIG. 2 in the drawing shows a front elevation view of the device.
  • FIG. 3 in the drawing, represents a cross-section view, taken along the line “A-A” of FIG. 2.
    • DESCRIPTION OF THE “PNEUMATIC-AQUATIC”, FRICTION AND WATER PRESSURE REDUCING DEVICE
  • Referring to FIGS. 1, 2 and 3 of the drawing, the device can be made of sheet steel materials.
  • The container is supported by structural steel members, as shown, and an air supply pipe in the middle.
