US 2009/0317249 A1 · DRAG-REDUCTION, PROPULSION, AND LIFT GENERATING SYSTEM

Abstract

A motion generating system for propelling and/or lifting a craft exploiting explosive and implosive processes, whereby a propulsive or lifting force on the craft arises from two sources: generation of a stream of fluids which imparts thrust to the craft; and generation of zones of reduced pressure and density in front of and above the craft allowing the craft to be thrust forward and lifted by ambient pressure on the rear and underside of the craft. Furthermore, reduction of fluid density in front of the craft results in a reduction of frontal drag allowing the attainment of higher speeds. The motion generating system may have other applications; for example, the motion generating system may be used to propel a stream of liquid in the manner of a pump.

A motion generating system to control the relative motion of an object and a region of an adjacent fluid, comprising the object having a primary surface in continuous fluid communication with the adjacent fluid, a target zone disposed in the adjacent fluid and located relative to the primary surface, an implosion zone disposed in the adjacent fluid and located relative to the primary surface and any fluid present in the implosion zone is in close thermal and pressure contact with the primary surface, a means for introducing a hot fluid from the object into the target zone, a transfer path along which the hot fluid can transfer from the target zone to the implosion zone, and when the hot fluid enters the implosion zone heat exchange between the hot fluid, the primary surface, and the adjacent fluid in and around the implosion zone develops or maintains a dynamic pressure reduction in the implosion zone to cause regions of the adjacent fluid, the hot fluid, and the primary surface to be relatively propelled towards each other.

A method of controlling the motion of an object in an adjacent fluid comprising the steps of providing the object immersed in the adjacent fluid with an expansible envelope enclosing a lower density fluid phase of a phase change substance, a tank connected to the expansible envelope and enclosing a higher density phase of the phase change substance where the higher density phase conversion to the lower density phase is endothermic, a valve to control the lower density fluid phase flow between the expansible envelope and the tank, a source of Brown's gas and/or hydrogen and/or hydrogen peroxide, and a primary surface;

of controlling the object to ascend in either an oblique glide or vertically;
of simultaneously controlling the gross density of the object to remain lower than the density of the ambient adjacent fluid during the ascent;
of optionally simultaneously increasing the buoyancy by operating the valve to release the lower density fluid phase of the phase change substance from the tank into the expansible envelope;
of simultaneously operating the source of Brown's gas and/or hydrogen and/or hydrogen peroxide to provide Brown's gas and/or hydrogen and/or hydrogen peroxide;
of simultaneously projecting or injecting and igniting the Brown's gas and/or hydrogen and/or hydrogen peroxide and/or injecting their combusted products into a target zone in the adjacent fluid near enough to the primary surface to provide a steam plume making contact with the primary surface;
of simultaneously controlling conduction of heat from the primary surface to the phase change substance in the tank to maintain condensation of the steam plume and conversion of the phase change substance to the lower density fluid phase;
of optionally simultaneously recovering and storing the condensed water from the primary surface;
of controlling the object to maintain higher altitudes while converting the phase change substance lower density fluid phase to the higher density;
of simultaneously controlling heat transfer from the phase change substance to the adjacent fluid;
of simultaneously controlling the lower density fluid phase of the phase change substance to enter the tank and convert to the higher density phase of the phase change substance;
of controlling the object to descend in either an oblique glide or vertically;
of simultaneously controlling the gross density of the object to remain higher than the density of the ambient adjacent fluid during the descent;
of simultaneously if necessary continuing to convert the lower density fluid phase of the phase change substance to the higher density phase of the phase change substance;
of simultaneously retaining the higher density phase of the phase change substance in the tank;
of optionally simultaneously thermally insulating the tank;
of simultaneously operating the source of Brown's gas and/or hydrogen and/or hydrogen peroxide to provide and store the Brown's gas and/or hydrogen and/or hydrogen peroxide;
of controlling the object to maintain lower altitudes while converting the high density phase of the phase change substance to the low density fluid phase of the phase change substance;
of optionally simultaneously controlling the gross density of the object to remain equal to the density of the ambient adjacent fluid in order to hover the object;
of optionally simultaneously controlling heat transfer from the adjacent fluid to the high density phase of the phase change substance in the tank or providing heat from another source if the ambient adjacent fluid's temperature is too low;
and of repeating the steps in a cycle in order to further translate the object horizontally with net thrust and low resistance from the adjacent fluid, or to further convert gravitational and thermodynamic energy for other purposes.
