(54)Title: POWER AND PROPULSION SYSTEM UTILIZING FLUID (57) Abstract A system for generating power, buoyancy or propulsion force comprising power generating means and propulsive means.

The power obtained by utilizing the compressibility of a fluid passing through a fluid passage is utilized for buoyancy or propulsive system without being influenced by the outside of the bodies of an airplane or ship. Upon being operated by outside electric power, the power generating means continuously produces electric power even when the supply of the outside power is stopped.

That is, the self-generating power ;nay be utilized for obtaining buoyancy or propulsion force. The self-operating power generating means may operate continuously by sucking heat from an outside fluid. The electric energy produces a force exerting in one direction within the airtight room of the propulsion means. With this construction, an airplane, vehicle or ship may be safely operated even in an abnormal phenomenon. Furthermore, heat exchanger means may be served as a cooling system.

c -i WO 92/21862 PCT/KR92/00020 1- PCOER AND PROPULSION SYSTEM UTILIZING FLUID Detailed Description of the Invention This invention relates to a power and a propulsion systems wherein the power is obtained by utilizing the compressive force of fluid passing through a fluid passage and the power is applied to a buoyancy or propulsion system without influencing the exterior of the body of an aeroplane or ship.

A power system which is presently used, to propel aeroplane, ship or vehicle, is operated by the high-speed rotation of an engine which is operated by an oil fuel. For example, an aeroplane's body is propelled by the rotation of jet engine while the buoyancy of the body is obtained by the lift utilizing the curved airfoil.

In case of a ship or a vehicle, their bodies are propelled by power transfer means which operated by the rotation of engine.

The above-described power generating system results in the consumption of large amounits of energy. Furthermore, the structure of the typical system is complex, causing a frequent breakdown of the system and a rise in the manufacture cost.

In particular, a buoyancy system is required to buoy the aeroplane or ship. helicopter and airship are propelled and buoyed by the rotation and curved configuration of the airfoil which contacts directly the air. The propulsion and buoyancy of the helicopter and WO 92/21862 PCT/KR92/00029 2 airship are influenced by such weather conditions as irregular air current or difference of air density, thus resulting in the abnormal phenomenon which may cause the suspension of the operation of the ship or the aeroplane, or a sudden accident.

Another object of the present invention is to provide a power system which is simple in construction and effective s in operation.

Still another object of the present invention is to provide a propulsion system wherein fluid flows within an airtight room and propulsion force is produced in one direction, whereby buoyancy or propulsion may be exhibited independently of the outside air.

A propulsion system 200 is provided with a driving motor M, a rotation body 210, an absorp t i on airfoil 221, a support body 220 and an enlclosed compartment 250.

The driving motor M is driven by the electric power from the power generating system 100. Airfoils 211 are fixed slanted on the periphery of the rotation body 210 to move fluid downwar The absorption airfoil 221 is provided with several minute grooves 222 and mounted on the support body 220. The grooves 222 are slanted in the same direction as the airfoil 211 of the rotation body 210 and are provided in the opposite surface of the airfoil 211.

With the grooves 222, the downward flowing direction of the fluid moved by the rotation of the airfoil 211 is converted and the compression of the fluid is fluctuated turblently.

Propulsion means is constituted by the airfoils 211 and the absorption airfoils 221 and provided in the enclosed compartment 250 of which upper and lower surfaces are enclosed by the support body 220. e fluid in the enclosed compartment 250 has buoyancy or propulsion produced upwardly.

The power generating system 100 produces power by means of the fluid velocity increasing means 130 which increases fluid velocity of the fluid filled in the fluid WO 92/21862 PCT/KR92/00020 8 pipe 120 by the character of the fluid passage.

Fig. 4 shows a first embodiment of the power generating system 100 wherein the motor M, compression means 110, fluid velocity increasing means 130 and turbine 140 are provided at one side of the fluid pipe 120 in which fluid is filled.

The electric motor M rotates the compression means 110 upon being driven.

The compression means 110 is a centrifugal pump type in which, as shown in the drawings, rotating wings are mounted radially and have a straight or radial type and guiding wings 112 for turning the fluid which directs directly and induced to an induction port of the center of the pump, toward the circumference, minimize the angle with the rotating direction of the rotating wings. When induced, the fluid has the same direction as the fluid in the turbulent compartment 113 at the outside of the rotating wings. With the above arrangement, the fluid is turned at the outside of the guiding wings 112, thus producing centrifugal pcner by which compression effect is increased.

With the above-described construction, the fluid filled in the interior of the compression means 110 is compressed at the exit thereof. When fed by strong feeding force, the fluid is induced to the inlet of the fluid velocity increasing means 130.

The fluid is fed and turned, having an angle with respect ot the the center 132, like the direction shown in WO 92/21862 PCT/KR92/00020 9- Fig. 15. By the centrifugal force of the turning fluid, the compression of the fluid at the center 132 is lcaenr at the small- radius location than at the large-radius location of the center 134, and in proportion to the radius to the critical point. With this construction, the compression of the fluid is higher than at the exit of the guiding wing 131. The fluid is emitted to the discharge port at the state of increased kinetic energy compared with the inlet and drives the turbine 140 to obtain electric energy.

The power to operate the turbine 140 may be obtained by a single fluid velocity increasing means 130. However, to obtain further stronger power, a number of the fluid velocity increasing means 130 (In the drawings, three means are shown) are desired to be connected in series. With this arrangement, gradual l increasing force is obtained before electric energy is obtained. To minimize the decrease of the effectiveness caused by the diffe ence of the fluid velocity among each fluid velocity increasing means, the fluid pipe at the exit of each fluid velocity increasing means is desired to be made as a straight pipe which is extendible gradually at the sectional area thereof.

"ne wing of the turbine 140 sre forced to be rotated by the feed of the fluid to obtain electric energy.

The fluid, after having been compressed by the fluid veloity increasing means and by the turbine 140, is cooled. The fluid is further cooled by the repetitive induction from the compression means 110 to the fluid I WO 92/21862 PCT/KR92/00020 10 velocity increasing means 130, whereby the operation of the system is stopped. To keep the system being operated, a heat-suction pipe 151 and a heat exchanger 150 are mounted in the middle of the fluid pipe 120 which constitutes a closed circuit.

The heat exchanger 150 supplies the outside air to a radiator 152 by a fan 153 and compensate heat for a heat transmitting pipe which transmits heat to the cooled fluid to maintain the normal temperature. With this arrangement, the interior of the fluid pipe 120 has adequate temperature by the radiating pipe.

Accordingly, the power generating system of the present invention operates smoothly at the normal temperature.

The fluid velocity increasing means has their inlets and outlets contacted with one another and increases the fluid as followings.

As shown in Figs. 5 and 6, when flowing through the suction port of the fluid velocity increasing means 130 by the compression means 110, the fluid has the direction of the fluid passage out of the center of the centripetal axis 132 by the guiding wing 131.

Accordingly the fluid toward around the centripetal axis 132 turns around the centripetal axis, thus producing the centrifugal force. By the centrifugal force, the compression of the fluid is low at a small-radius location.

However, to the critical point the larger the radius is, the O L SWO 92/21862 PC i/KR92/00020 11 higher the compression of fluid is.

In the biginning, the compression of fluid is different at a large-radius location by the centrifugal force. The direction of fluid which is turning around the centripetal axis 132 at a high-pressure location does not disturb flowing fluid even though the fluid pressure at the high-pressure location is higher than that at the exit of the guiding wing 131. The reason is that the centripetal force corresponding the centrifugal force is formed in the center part, whereby the velocity component acts as joint forces which joins a straight driving component (centrifugal force with suction force toward the center part), and turns.

Accordingly, the kinetic energy of fluid at the exit is greater than that at the suction port, there)-y producing the kinetic energy of fluid increased over that of fluid pushed by the compression means 130.

The grade of an oblique angle of the fluid of the exit of the guiding wing 131 with respect to the center is adjusted by the fluid velocity and compression difference between inlet and exit. It should be noted that, when the angle is adjusted, the fluid, when sucked, is further slanted towards the direction of the center as the fluid velocity is the greater. As shown in Fig. 19, to minimize the decrease of the effect caused by the decrease of the fluid, the fluid pipe at the exit of the compression means 110 is desired to be made as a straight pipe which has a gradually increasing section area.

WO 92/21862 PCT/KR92/00020 12 The fluid velocity increased as the above-described way drives the turbine 140, thus rotating the motor and the compression means 110. The fluid having its energy re-reduced is fed to the exit from the suction port of the fluid velocity increasing means 130 to obtain strong and fast energy and circulated. At this time, the remaining electric energy in the turbine 140 after driving the motor rotates a generator 141, thereby being utilized to operate other electric appliance used for another purpose.

Fig. 15 shows another fluid velocity increasing means 130 comprising a number of fluid velocity increasing means elements connected one another, wherein suction port 134 and exit 135 fluid pipe are of cylindrical shape and the guiding wing which is located at the exit and directed in the center converts the fluid flowing in the center so that the fluid passes around the centripetal axis Pand then turned toward the axis direction naturally.

Fig. 7 is a second embodiment of the fluid velocity increasing means 130. The construction of the powr generating system in the second embodiment comprises the same elements as that of the first embodiment. However, the type of the fluid passage in the means 130 is different.

A disk-shaped fluid passage converts the fluid flowing in the centripetal direction to a radial direction. For this purpose, the disk-shaped fluid passage has a curved surface 133 so that the fluid flows _erpendicular to the flowing- in direction. A guiding wing 131 is mounted in WO 92/21862 PCT/KR92/00020 13 the middle of the curved surface 133 and has the same diaieter of the inlet.

The guiding wing 131 is designed in such a manner that the radially discharging fluid is gradually converted with a smooth curvature and discharged toward the periphery at one end of the guiding wing.

The fluid having been compressed initially flows in the inlet of the fluid velocity increasing means 130 and is turned along the radial fluid passage and then discharged to the oulet of the fluid pipe 120. Thereafter, the direction of the fluid flowing straightly at the end of the guiding wing 131 is changed by the direction of the inner surface of the fluid pipe 120, thereby centrifugal force and force further compressing outward fluid toward the exit are produced, resulting in the difference between the compression of the fluid near the center and the centrifugal force acting on the outward fluid. Consequently, the compression at the inlet of the fluid velocity increasing means 130 becomes greater than that at the outlet of the means 130, thus resulting in substantial kinetic energy of the fluid. Accordingly, power is obtained by the remaining kinetic energy of the turbine 140.

Fig. 10 is a third embodiment of the fluid velocity increasing means 130.

A U-turn fluid passage is added to the outside of the fluid passage of the secone embodiment. A curved surface 133 is provided at the interior of the center. A plurality I I 1 WO 92/21862 PCT/KR92/00020 14 of guiding wings 131 are spaced and extends radially .The guiding wings 131 are of a curved shape. Inlets and outlets are connected with one another. The inlet has tuo passages and the outlet has a divided two fluid passages. The fluid flows in the suction port 134 of the center and the suction port 136 of the outside, respectively.

With the two suction ports, the fluid turns from the outside of the cylindrical formation to the circumference, and then makes a U-turn. The oneside of the fluid pipe 120 enclosing the guiding wing has small diameter and the other end has large diameter. With this structure, the diameter increases gradually from the inlet to the outlet, resulting in the outlet having a maximul diameter.

Accordingly, the fluid having been sucked in the guiding wing 131 flows in the center and then turns toward circumference. Thereafter, the compression at the outside increases by the centrifugal force. The velocity component of the fluid spreads toward the center of the fluid pipe 120. The velocity component spreaded toward the center is utilized to turn the fluid at the outlet of the guiding wing 131. Consequently, the fluid at the outlet increases by the centripetal and centlifugal force.

Fig. 11 shows a third embodiment of the fluid velocity increasing means 130. The suction port 137 at the outside is used as a passage through which the fluid is fed by the compression means 110. The suction port 138 of the center is open to the outside. In the suction port 130 is sucked tullPC~e~tr-~c~ WO 92/21862 PCT/KR92/00020 15 outside fluid other than the fluid flowing in within the pipe. With this construction, the fluid at the center turns by the influence of the fluid flowing in the inlet 134 and the outlet. When the pressure at the center decreases by the centrifugal force, the outside fluid is sucked. The same amount of the outside fluid as the amount of the fluid which is sucked in tc the center from a portion of the fluid pipe of the circulating passage, is discharged. A portion of the circulating inner fluid is discharged and sucked.

With this costructure, the velocity increasing means las both a closed a.nd an open passage.

Fig. 12 is a fourth embodiment of the fluid velocity increasing means. As the most different construction, a ladder-shaped fluid pipe is additionally provided. The 1adder-shaped pipe is wound spirally and has a gradually decreased curved radius. With the ladder-shaped fluid pipe, the pressure of the fluid passing through the spiral pipe is low at center having a small curved radius, and the pressure of the fluid flowing near an outside wall 161 is high. As the curved radius of the outer wall of the spiral pipe decreases gradually, the adjacently flowing fluid provides biased force toward the center with a portion of the ouside fluid, by a collision with an outer surface of the spiral pipe.

With the biased force, the centripetal force is strengthened. The strengthened centripetal force incr-ease.s the velocity of the fluid. As the length of the inner wall WO 92/21862 PCT/KR92/00020 16 or center axis and the outer wall 161 of the spiral pipe gradually lengthened, the biased force toward the flowing direction of the fluid is strengthened and the velocity of the fluid further increases since greater biased force is formed around the center axis.

As shown in Fig. 12, when the spirally extending center axis at the outlet is thicker than other portion, only the high-pressure fluid at the outside is discharged, thus obtaining stronger kinetic ene-gy.

It is desired that the spiral pipe 160 be gradually, upwardly lengthened at the outer wall 161 and inner wall and an interior angle between the bottom face of the fluid pipe and the outer wall be uniform.

With the length of the outer wall 161 which is maintained toward the oulet, same effect may be obtained even the sectional area of the fluid passage decreases gradually toward the outlet. As shown in fig. 14, the fluid pipe may have a square shape in its cross-section.

Fig. 13 is a cross-section of the spiral pipe 120 having a cut-away portion. The spiral pipe 120 is wound upwardly, spirally.

Figs. 16 and 17 shows the compression means of the pcwer generating system. The compression means is provided 'ith a fluid pipe having the same construction as the velocity increasing means. At the outside of the guiding wing 112 of the fluid pipe is provided a plurality of radially extending straight and short rotatable wings 111.

v O 92/21862 PCT/KR92/00020 17 With this arrangement, the angle when the fluid at the outlet is turned and sucked conforms with the rotation direction. The construction of the rotatable wing is similar to that of the radial-winged centrifugal fluid duct.

However, the rotatable wing is short and narrow upper and lower ends. The effect of the compression system further increases since the direction of the fluid sucked in the rotatable wing conforms with the direction of the rotatable wing. Further, the pressure at the outlet increases by the 1 centrifugal force of the turning fluid.

Fig. 18 shows another embodiment of the compression means wherein the suction port 139 is provided at the both sides of the axial direction.

Fig. 10 shows a fluid passage dividing pipe which is provided at a location at which the section of the fluid passage of the suction port decreases of the fluid velocity increasing means of the power generating system. The fluid passage dividing pipe is provided with a plurality of coaxial cylindrical fluid pipes of which leading end is thick and rear end is thin. With the coaxial cylindrical pipes, the fluid from a large-sectioned location of the fluid pipe is sucked ur 'formly over the whole section of the fluid pipe. The section of the fluid pipe between the fluid dividing pipes is greatly decreased at the leading end. To the rear end, the fluid pipe has a uniform section or a section of small reduction rate. It is noted that the pipe has any configuration at its section, such as square or oval WO 92/21862 PCT/KR92/00020 18 shape. The heat exchange system 150 exchanges the fluid of ordinary temperature with the inner fluid by means of heat and supply heat to the inner fluid. The heat exchange system comprises a fan 153, a radiator 152 which is connected to a heat sucking pipe 151 and a compressor. With the heat exchange system, the over heat of the fluid circulating the interior of the fluid pipe is prevented, resulting in the smooth operation.

Fig. 21 shows the heat exchange system 270 to compensate heat for the interior of the system by absorbing the heat of the normal temperature of the outside of the system. With the heat exchange system 270, the freezing of the moisture in the air by the absorption of the heat of the air, is prevented.

In detail, the freezing of the heat exchange system 270 is prevented by the following repetitive process, that is, a water-soluble antifreezing solution flows in the interior of the radiator and then is raised along a guiding pipe to the circulating system consisted of a pump.

When the antifreezing solution becomes low in its concentration the solution passes through the fluid pipe in a dry tank which is provided with curved radiating pins and then is heated by a heater 277 under the fluid pipe, whereby the air in the upper space of the dry tank is discharged by a vacuum pump 279, resulting in the interior of the dry tank 276 being made vacuous. Consequently, the solution is returned to a moisture-evaporated ordinary WO 92/21862 PCT/KR92/00020 19 solution, thus permitting a repetitive use of the antifreezing solution.

The heat exchange system 270 heat cool air of the interior of the propulsion system 200. With this construction, the heat exchange system 270 supply heat to the outside heat sucking pipe 272 by means of a fan 271 which is located at one end of the radiator 273 while cooling some objects by the cool air from the heat suction pipe 272. As described above, the heat exchange system 270 may be utilized as a cool system such as air conditioner or a refrigerator.

Fig. 1 shows the fluid velocity increasing means of the power generating system 100 wherein the pressure of the fluid increases by the centripetal force. Fig. 2 and 3 show spiral piped fluid passage of the fluid velocity increasing system and the power generating system utilizing centrifugal force, respectitively.

In the propulsion system 200 the pressure is produced to one side according to the flowing direction of the fluid and the pressure is absorbed in the other direction. The difference between the produced and absorbed pressure results in producing buoyancy or propulsion.

Fig. 32 is a first embodiment of the enclosed propulsion system 200, wherein the driving motor M is rotated by electric energy obtained from the power generating system 100, thus rotating the rotatable body of cylindrical shape which is open at its upper and lower ends.

is provided with an electric motor compression means 110 which produces feeding force from one to the other WO 92/21862 PCT/KR92/0002 20 The rotatable body 210 has slanted, multi-stepped, cooperable wings 211 on the periphery thereof. Each of the wings 211 is wide and should be mounted in such a manner that the angle between rotation direction and the wing is small.

The support body 220 consists of upper and lower surfaces 223, 224 and side surfaces to tightly close the rotatable body 210 and wings 211. The support body 220 has wings on the inner face fixed thereto which are crisscross with and have the same slanted direction as the wings 211 of the rotatable body 210.

As shown in fig. 13, the wing 221 has minute grooves 222 in the upper face thereof to increase the area on which, when the fluid containing air or liquid flows downwardly, the fluid acts, and to decrease the downwardly acting pressure by the turbulent fluid in the minute grooves 222.

Accordingly, the wings 211 rotated by the driving motor feeds downwardly the fluid filled in the support body 220. Furthermore, the buoyancy to lift the wings 211 together with the rotatable body 210. In su. ,,ary, The phenomenon arises at every location at which the wings 211 and the crisscross absorption wing 221 rotate fast. The buoyancy force obtained at this time is united to be served as strong propulsion force or buoyancy.

The fluid moves downwardly by the rotation of the wings 211. The support body 220 has absorption grooves 225 in the lower surface 224 thereof having the same means of the fluid velocity increasing means 130 which increases fluid velocity of the fluid filled in the fluid i WO 92/21862 PCT/KR92/00020 21 configuration and construction as the minute grooves 222 in the wings 211. With this arrangement, the upwardly pressure by the fluid acts strongly further than the downwardly pressure, thus obtaining more stronger buoyancy.

The distal absorption wing 221' and other absorption wings 221 are mounted at different angle so that the fluid flows in the center in slightly deflected direction. With this arrangement, additional effect of the increase of the pressure of the upwardly fluid from the center, is obtained by the same theory as in the first embodiment of the fluid increasing means of the power generating system to produce the centrifugal force of the fluid flowing toward the center to adjust the direction of the fluid flowing through the center. In addition, the diameter of the bearing-supporting lc ation at the upper portion is larger than the center, thereby only high-pressure fluid having large turning radius is discharged and turned at the upper portion. As the upper and lower width of the fluid passage of the uppermost part of the upper being narrow, the pressure at the upper surface is higher than that at the lower surface, thus increasing the buoyancy further.

With the difference of the pressure acting on the upper part and the lower part by the movement of the fluid, buoyancy or- propulsion force from the airtight interior to one direction is obtained. The buoyancy or propulsion force is used for ships or airplanes.

In case the above-described systems of the same number

IL-

The fluid is fed and turned, having an angle with respect ot the the center 132, like the direction shown in WO 92/21862 PCT/KR92/00020 22 are mounted at both sides of and spaced equally from the center line of the airplanes or ships, respectively, the bodies of the airplanes or ships are lifted and balanced.

Furthermore, if the systems are mounted at the leading or rear end of the bodies with the lengthwise axis being parallel with the floor, the bodies are propelled toward the direction perpendicular to the byoyancy acting direction.

If the systems are mounted at the surface parallel to the direction intended to propel with the lengthwise axis being par allel with the floor, the bodies are turned from side to side.

As being provided within the airtight room, the systems are rarely influenced by weather change or a treacherous air current such as a storm, or the change of the air density, resulting in normal operation. Futhermore, an airplane can be taken off and landed perpendicularly without using a runway.

In case the the above-described system is used as a buoyancy system, an outside body 230 is fixed to the outer surface of the system to prevent overheat which may be caused by the movement of the fluid. The outer body 230 is open at its upper and bottom surfaces. With the rotation of the rotatable body 210, the outside fluid flows along the outer surface of the support body 220, thus bringing oil cooling or air cooling Conversely, in case the above-described system is used as propulsion system, the fluid within the airtight room is apt to be cooled. To EL L *WO 92/21862 PCT/KR92/00020 23 prevent the cooling, heat may be supplied to the interior fluid from the outside fluid.

It is desired that the fluid in the airtight room 250 have uniform pressure and the uniform pressure be exerted on the interior of the airtight room 250. Even not shcwn in the drawings, an extra fluid reservoir and pressure control device comprising a pressure sensor and a suction or discharging pump are desired to be mounted at a suitable location out of the airtight room 250.

The pressure control device comprises a rotatable body 210 and a support body 220 which are rotated respectively.

With this construction, to rotate the rotatable body 210, the center bottom of the rotating axis 212 of the rotatable body 210 communicates with the interior of the airtight room 250 so that a pressure is controlled by the incoming and outgoing of the interior fluid in respect to pressure control tube and the airtight room 250 through an opening in the rotating axis 212.

That is, an upwardly pressure is increased by the fluid at the upper surface and a downwardly pressure is decreased at the bottom surface, resulting in the production of the buoyancy. The effect is further increased in that the effect of the compression of the fluid is additionally obtained.
