Gas Turbine Thrust Fuel Efficiency Enhancement System Water (Volatile) Introduction Arrangement Method and Means   (20120272635 )    
Inventors: Len Andersen.  Filed April 27, 2012  in United States

Abstract Additional thrust fuel efficiency is provided for a gas turbine system that includes a first member(s) (e.g., a support for a rotating main shaft) that is attached to a stationary casing. The rotating main shaft is attached to the first member through a bearing. A second member is associated with a rotating member, such as a motor or other rotating part of the main or other shaft. The first member has a flow path in it for the liquid (e.g. water and/or other volatile liquid) and has an opening (nozzle) for discharging the liquid. The second member has a liquid impinging member for generating a liquid spray, droplet, mist optimally, which vaporizes with hot combustion gases that flow exteriorly along the main shaft. In this form vaporization is quick and is less erosive. The volume of thrust gases is increased advantageously and likewise engine boost increases.

The methods involve the injection into a borehole of an water/oxygen slurry which releases oxygen gas as it flows into the reservoir and recovering, at a later time following in-situ combustion and/or reaction, an improved energy material yield from said borehole or adjacent borehole.

Heavy Frac'ing Method For Last Plus 30 years. Heard it is the way much of shale is happening. I participated in first use in North Slope of Alaska! Other use going back thirty years is contour and profile control and heavy use with naturally fractured limestone. Robert C Sullivan was the partent attorney that assisted me. A method for recovering energy raw materials from a subterranean formation whereby a gas or liquid is injected into the borehole and adjacent formation and vented as required to prevent undesirable combustion or reaction with the introduction of a cryogenic liquid containing oxygen. This cryogenic liquid, when introduced, yields unexpected benefits by its tendency to flow downward and horizontally along the bottom barrier of the pay zone, forming pockets, reacting with material in the formation, fracturing the formation, simultaneously in close proximity heating by combustion and cooling by vaporization, and yielding a unique displacement (flood) due to combustion, reaction and volitallization products formed. There are two preferred embodiments, first introducing the cryogenic liquid containing oxygen into a borehole and after a period of time producing from the same borehole. Second, introducing the liquid into a pattern of injection borehole(s) and forming a mobile from which can be pushed by another injected liquid or gas and producing from another borehole or other boreholes.

Authors: Len Andersen BSChE Engineer Available Welding Inspector CWI, Ed Ellis P.A. / LeasonEllis.com.  Published January 01, 2011

A turbine arrangement is provided for use in a gas turbine engine that includes a combustion chamber and a nozzle. The turbine arrangement includes a source of liquid and a turbine blade assembly that is rotatable about a central shaft. The blade assembly further includes a plurality of turbine blades, the blade having a forward edge that faces the combustion chamber and an opposite rear edge. A hollow interior of at least one blade is in fluid communication with the source of liquid. The blade (e.g. a rear edge thereof) including a plurality of openings in communication with the hollow interior and sized to produce liquid droplets for discharge downstream of the turbine blade to generate a gas (e.g., steam) due to contact with hot gases generated by the combustion chamber. The rotation of the turbine blades and discharge of the liquid in droplet form causes the liquid droplets to travel in a non-linear pattern resulting in conversion of the liquid droplets to the gas and an increase in volume for the hot gases, thereby resulting in the hot gases leaving the nozzle with increased thrust.

On the first test the results were on initial decrease in injection pressure and a 20% increase in production for 40 days. The oil field was an irregular six spot water flooded, Gun Sight Sand unconsolidated channel sand formation at a depth of 520 ft. (158 m.). In the second field test oil production increased 20% for 300 days, water injection pressure done on a batch basis increased from 0 to 230 psi (0 to 1590 kPa) to a range of 300 to 550 psi (2068 to 3790 kPa), and oil production from a deeper formation doubled. The oil field was an irregular, five spot, water flooded, Strawn Sand (consolidated sand with limestone formation at a depth of 1900 ft. (579 m.). These tests indicated the water/liquid oxygen process would be an economic success done on an going basis in similar oil formations.

Pursuant to inventiveness I came up with an invention that allowed welding attachment to whatever to the bottom of the sea. Since 1974 I have had contact with USN and Central Intelligent Agency on the use of said invention for such purpose inclusive of salvaging a soviet submarine from 18,000 fsw. Exothermic welding device for welding to a surface underwater includes a Thermit charge surrounded by a movable inner casing abutting a plate. The plate includes magnetic or other means for attaching the device to the surface to be welded. Urging means force the Thermit melt through the surface. The urging means disclosed are a weight, spring, or pressure system arrangement. An outer housing surrounds the inner housing and urging means, and joins the plate. The device may be used for underhand or overhead welding, or to a vertical surface.

A submersible device for use in salvaging metal objects comprises a magnetized metallic housing containing compressed thermit suitably sealed from the water. The housing in lowered on cables until its magnetic field causes contact with the object to be salvaged. The thermit may be ignited by a voltage applied to a wire which is returned to the vessel from which the housing is deployed. When the thermit ignites, it produces a molten metal which burns through the bottom of the housing and forms a weld between the housing wall and the surface of the metal object to be salvaged. The object may then be raised by pulling on the cables supporting the housing.
