Abstract

Ellipsoidal Submarine (1) and its specific form - a disc (2) or a ball, is a new type of water vessels. Ellipsoid is characterized by an ellipse profile when looked from direction of all three axis. Vessel in disc form is characterized by an ellipse profile in vertical and circle in horizontal cross section, and a ball is characterized by a sphere i.e. a circle looked from all directions. Basic stabilization of ellipsoid 1, disc 2 or ball submarine, at travel or standing still, in water or on it, is accomplished by special stabilizer (11), mega gyroscope inside. Stabilization is supplemented by a group of water jet motors (10) for vertical drive and wing stabilizers (3). The submarine drive is accomplished through groups of: water jet motors for forward travel (4) and (9), water jet motors with double action of jet (10) for vertical travel, water jet motors (6) for maneuver, forward travel and stopping, and such motors (8) for sudden lateral moving of special purpose submarines. For stopping at sea bottom it uses breaking unit. With groups of water jet motors and by its shape a submarine may reach a speed in water up to 250 m/s and on water up to 300 m/s, with full stability at travel.

Description

ELLIPSOIDAL SUBMARINE

TECHNICAL FIELD IN REGARD TO THE INVENTION The invention belongs to the field of water vessels i.e. to the field of new natural shapes of submarines in the form of an ellipsoid and its specific forms-a disc and a ball, with great maneuver capabilities and sharp direction shift, with fast immersing or surfacing, driven by turbo jet pumps-water jet motors to reach high speeds. According to the International Invention Classification (IIC) the designation would be: B 63 B 3/13 B 63 G 8/00

TECHNICAL PROBLEM How to solve a submarine shape to have small moving resistance coefficient in water for reaching very high speed when carrying cargo, to have good stability at travel or standing still, to have rapid immerging or surfacing, fast direction shift, great maneuverability, easy steering. These, but also other problems are solved by a submarine of an ellipsoid shape and its specific forms - a disc or a ball.

BACKGROUND ART Submarine gets its first practical importance by fitting of internal combustion (diesel) engine as a drive which increased displacement, diving depth and travel speed in water and on water surface. Diving depth has been also improved with science and engineering development. During World War I diving depth used to be about 80 m, in the Second World War about 200 m, and in late sixties when submarines on atomic drive were built, it was above 500,. That is how the American submarine NAUTILUS with atomic drive passed under the ice cover of the North Pole on Aug. 3, 1958. Submarine speed depends on drive type. Classic ones are driven by internal combustion engine and they have the speed of 45 km/h (12.5 m s) at water surface and about 36 km/h (10 m/s) under water. Atomic submarines have speed of about 60 km h (about 17 m/s) both in water and on its surface. Submarine action radius depends on the type of drive. Atomic drive submarines have action radius of about 200,000 km. practically, they may stay under water infinitely and the limit is physic and psychic endurance of crew. Displacement also depends on the drive type and it is from 1001 of small classic, to over 8,0001 of submarines on atomic drive. An idea to built gigantic trade submarines with displacement of over 800,000 t has not been realized yet. Submarine application makes sense as under water traveling cuts short distances between some points on Earth. Till today it was not known that a submarine had shape of ellipsoid or disc and fast moving above 100 m/s and that a submarine could move equally well on water as a ship. That is why it can be said that this is quite new type of submarine with large potentials: to transport heavy cargo at high speed, to have great maneuverability, stability at travel and standing still.

DISCLOSURE OF INVENTION ESSENCE Ellipsoid vessel in water-a submarine and its specific form a disc, and a ball, is absolutely new vessel natural shape of submarine which enables further development of submarine engineering with new drive type i.e. it increases size and speed. The essence of the invention is a new, natural shape, great stability when traveling or standing still and new drive that enables transport of heavy cargo at high speed. Ellipsoid water vessel is a submarine in shape of an ellipsoid-in all projection flats there are ellipses (xOy, xOz, yOz). The larges one is in a horizontal flat xOy with semi-axis ratio a:b of 1.5:1 to 5:1. Then, ellipse in a vertical longitudinal flat xOz with semi-axis ratio a.c from 3:1 to 10:1 and more. The smallest is in a vertical flat transversal with semi-axis b and c. As a rule, increase of a submarine and these ratios of semi-axis are bigger. Double sum of semi-axis a gives length, double sum of semi-axis b gives width and double sum of semi-axis c (or sum Ci plus c₂) give submarine height. Disc water vessel as a specific ellipsoid form is a submarine in a disc form-in a horizontal flat there is a circle, in a vertical there is ellipse. It means that circle radius R equals ellipse semi-axis a and diameter gives submarine length and width. Double sum of semi-axis b (or bi and b₂ at some designs) gives submarine height. Semi-axis ratio a.b are most often 1:1 to 10:1 meaning the bigger submarine the bigger ratio. Of course, when a ratio is 1 : 1 there is a spherical shape, a ball shaped submarine. It can be seen that a disc is a special ellipsoid form when semi-axis b equals semi-axis a but due to a specific form they are given as separate submarine shapes. Also, ball shaped submarine is, further on, specific form of a disc, and that is why this shape is stressed. As a rule, ellipsoid is used for very high displacements, over 1 million tons, with rather law speed of travel or for lower displacements and higher speeds. Disc submarines are used first of all for special purposes, high speeds, medium displacements, passenger transport at lower depth, for underwater tourists, underwater research. Ball submarines are used for lower speeds and deep diving, as rescue submarines for big ones, research at big depths and for underwater tourism. Space division in submarine depends, also, on its size and purpose. For large tourist submarines certain number of small ball submarines must be anticipated. They will serve as rescue boats of a ship, in case of damage. Similar must be obtained for crew of cargo or special purpose submarines. Ellipsoid, disc or ball submarine stability in travel or standing still on water and under water is the most important characteristics. Good stability gives safety to submarine, people and cargo in it. The basic stability of submarine, especially when traveling on water, is arranged by special stabilizer, mega gyroscopes described in patents "Disc Flying Object" and "Ellipsoid Flying Object". It is positioned and it has the same function as in these patents. Here it must have only higher kinetic torque, i.e. it must be "stronger". Also, stabilization in travel mode is achieved by wing stabilizers positioned between water jet motors for forward travel, as described in patent "Ellipsoid Vessel". As a rule, disc and ellipsoid submarine on water surface behave as a vessel of the same size and shape, both in travel or stand still. The advantage of a submarine is that in stormy weather, at troubled sea with high waves, it may immerse and move as if there were not a storm. That is why, here only a travel of a submarine on calm water, or very small waves on water, will be described. Basic stabilization is achieved at above mentioned stabilizers. Keeping a submarine in a horizontal position at travel is done the same as for a vessel of the same shape, as described in patent "Ellipsoidal Vessel". Stability of ellipsoid, disc or ball submarine when traveling under water is achieved in many ways. The basic one is by described special stabilizer. However, stability at travel and standing still may be done by a group of water jet motors with double jet action for fast immersing and surfacing, i.e. by a group of motors for submarine vertical travel. When submarine in water travels or stands and due to some impact it is inclined, at that side water jet motors with double active jet are activated. They act upwards. On the other side, motors from the same group are activated and they act downward, so that forces jointly return a submarine to horizontal position. This is a fast and efficient way to stabilize a submarine if there is not sufficient stability by special stabilizer. Slower stabilization is trimming-overflow of water from one to another tank, as it is done nowadays with current submarines. There are also telescopic wings for stabilization. Moving of ellipsoid, disc or ball submarines is enabled by corresponding groups of turbo jet pumps-water jet motors, described in so-called patent. A group consists 2 to 11, or even more, water jet motors. Certain number of motors is used depending on desired force to move a submarine ay desired speed and they operate in an optimal regime i.e. with highest efficiency level. If only one big motor is used, it would work very little in an optimal regime with top efficiency level. Ellipsoid, disc or ball submarine has outriggers on the bottom, four as a rule, similar to braking unit of disc or ellipsoid flying objects. It is described in so-called patents, but here they are modified to water conditions. These outriggers are necessary for cases of "landing of submarine at sea bottom" not to "sit" on water jet motors. These are cases of standing still of special purpose submarine, or in research of sea bottom, or when there is some possible damage. Production of electricity for operation of water jet engines is by an electric generator of high voltage and higher operating frequencies. To initiate a generator, a steam or gas turbine or speedy diesel motors may be used. Steam for steam turbine operation may be produced in classic boilers of liquid fuel or in nuclear reactors. In near future, by plasma reactors.

DETAILED DISCLOSURE OF THE INVENTION There are two geometrical forms dominating macro world-a circle and an ellipse, i.e. bodies-a ball and an ellipsoid. This is the basis of ellipsoid and its specific form a disc, and a ball, a vessel in the water-a submarine, as natural ones. Ellipsoid water vessel is a submarine in the shape of ellipsoid 1. When looked from all axis, x, y and z, ellipses can be seen. The biggest ellipse is in horizontal flat, xOy, seen from z axis direction, with semi-axis a and b. Ellipse in longitudinal vertical flat, xOz, seen from y axis is with semi-axis a and c. The smallest ellipse is in vertical transversal flat, yOz, seen from x axis direction, with semi-axis b and c. Semi-axis ratio a:b is most often 1.5:1 to 5:1. Semi-axis ratio a.c is most often 3:1 to 10:1. The bigger the submarine, the larger semi-axis ratio. Double sum of semi-axis a gives the length; double sum of semi- axis b gives the width; double sum of c gives submarine height. When increasing semi-axis ratio, travel resistance coefficient in water travel reduces. Coefficient values of travel resistance must be measured in hydrodynamic tunnel and channel (described in patent at the same title). Disc vessel on water is a submarine in the shape of disc 2. When it is observed from x or y axis direction, a form of ellipse is seen with semi-axis a=R and b. When observed from the top, from z axis direction, a circle of radius R is seen and it equals semi-axis a of the ellipse. Semi-axis ratio a:b is from 1.5:1 to 10:1 and that depends on submarine size. Increasing of radius R this ratio is increased. Then, the value of resistance coefficient is reduced. Travel resistance coefficient values must be measured in hydrodynamic tunnel and channel for all semi-axis ratios. Diameter of a disc 2R gives length or width and double sum of semi-axis b gives its height. In case when semi-axis b equals radius R, disc is transferred to a sphere as its specific form. Then, a circle is seen from all directions. Ball submarine has the highest coefficient of travel resistance. This submarine shape is not used for big ones but for small, auxiliary and rescue submarines from big ones, and for research at great depth with a small action radius, but also for smaller tourist underwater journeys. Profile description shows that a disc 2 is a special ellipsoid 1 shape when semi-axis of ellipse b equals semi-axis a. Due to these specific shapes they are given separately and as described for ball submarine. As a rule, disc and ellipsoid are used for very fast submarines for special purposes, for underwater tourist traveling, underwater large researches. Ellipsoid submarines-king size is used for transport of very heavy cargo, over million tons, by the shortest underwater paths. The surface that separated the top and bottom part of an ellipsoid, disc or ball is called submarine floor and that is the basic platform. The frame and paneling are sized according to the size, purpose, diving depth and speed of a submarine. Due to its shape and load transfer, disc and ellipsoid submarines, special ball ones, do not require heavy frame and paneling. The frame is of steel profiles, first of all I profiles. Paneling is made of steel sheet. These submarines are made as single panel, as a rule. Decks, i.e. number of levels above and under the floor within a frame depend on submarine size. Some may be made out of profiles and alloys of some light metals (Al for example). Outer paneling side, the one to the water, must be covered by material with low resistance values when traveling and good anti rust protection. Outer paneling can be made of anti rust steel for a special purpose submarine. Ellipsoid 1, disc 2 and ball submarines have outriggers on the bottom 12. When traveling they are retracted into the body. As a rule, there are at least four outriggers and distribution of them as well as their function is similar to the braking unit of disc and ellipsoid flying objects (described in so-called patents), but here they are adjusted for water conditions. These outriggers 12 are necessary for the case of "landing" of a submarine at the sea bottom to prevent it to "sit" on water jet motors. These are the cases when a special purpose submarine is still, when there is some damage or when researching the sea bottom. Number and size of windows at submarine are designed by a designer depending on the size, speed, diving depth and on purpose. For example, shutters can be fitted to the outer side of windows for deep diving. In any case, submarine size must be arranged and it must be fitted with the equipment enabling perfect safety of people, equipment and cargo, especially for people rescue in case of possible damage. Stability of disc, ball or ellipsoid submarine, both traveling and standing still in or on water is carried out in many ways and that is important for its safety. The basic stabilization of ellipsoid, disc or ball submarine in travel or in standing still mode in water or on water is achieved by special stabilizers 11, mega gyroscope, described in patents :Disc Flying Object" and Ellipsoid Flying Object". It is positioned and it has the same function as described in these patents but it is stronger in the submarine i.e. it has higher self-kinetic torque of inertia. Position of this stabilizer 11 at disc, ball and smaller ellipsoid is central i.e. its axis i and axis z of a submarine align. At larger ellipsoid, when there are two of them, they are positioned so that their vertical axis, axis or ring turning, goes through the floor ellipse focus. Submarine stabilization at travel on water or through water may be supplemented by twisting wing stabilizers 3. Wing stabihzers are hydrodynamic profile and they are fitted between and around water motors 4 for forward travel. They may turn by hydraulic control from submarine. They turn around transversal axis for some small angleΞ. Lifting force of wing stabihzers 3 at submarine travel on water surface at high speed partially sets to balance the lifting force at the front part, as described in patent "Ellipsoid Vessel". When traveling through water wing stabilizers 3 may shift diving depth i.e. to be used as deep stern. Simultaneously, various values of turning angle 3 of wing stabilizers at left and right from travels axis, may balance some smaller outer forces tending to take submarine out of balance, or to shift direction of travel. Also stabilization of disc 2 and ellipsoid submarine may be done by trimming, as done nowadays, i.e. by trans-loading water from one to another tank for trimming. At travel of disc 2 and ellipsoid 1 submarine on water surface, the same forces are acting as for a vessel of the same size and shape, as described in patent "Ellipsoid Vessel" and they are set up to balance in the same way. Please note that a group of water jet motors with double jet action for vertical travel of a submarine must be disconnected at surface travel, as they are out of water then. Resistance force of a body through some fluid is known from fluid mechanics and it is: F _x = k_x * Δ * A * (v²/2) [N] Where: k_x- travel resistance coefficient of some profile Δ [kg/m³] - water density at certain temperature and depth A [m²] - submarine floor surface (A=a*b*B at ellipsoid and A=R² * B for disc and ball submarine) v [m/s] - travel velocity of submarine Values of resistance and lifting coefficients k_x must be evaluated in hydrodynamic tunnel and channel (described in patent of the same title) for specific ratio of semi-axis disc or ellipsoid submarine in function of water surface, although it may be in function of surface of front ellipse. As ellipsoid 1, disc 2 or ball submarine is octagonal symmetrical, for all three axis there are no lifting force at travel through water and there is no lift coefficient to be measured. When submarine travels on water surface, there is lifting force and it coefficient is to be measured. That a submarine is a vessel and ratio and conditions described for "Ellipsoid Vessel" are valid. This description illustrates that there are many ways to stabilize ellipsoid 2, disc 2 or ball submarines as it is the most important factor for safety of people, equipment and cargo at travel or standing in or on water. Disc 2 or ellipsoid 1 submarine may be driven by propeller as well (a screw) but it is not practical as it cannot reach speeds for full efficiency of these submarines but, also, for other previously described reasons. Basic drive of disc 2 or ellipsoid 1 submarine is turbo jet pump-water jet motor (described in a separate patent under the title). These submarines are fitted with groups of water jet motors for various functions and travel. The main group of water jet motors 4 and 9 is used for drive of submarine in order to move forward, in direction of axis x by designed speed. This drive maybe accomplished with one single motor, but more are used, from two to eleven, even more, and most often odd number. To move at specific speed one uses as many water jet motors as necessary to achieve this. Then they work in optimal regime i.e. at the top efficiency. When only one big motor is used, it works with small efficiency it vessel moves at small speed. Use of several small water jet motors has another practical point-when a large and one more motor is out of order, a submarine stops. When one from the group of smaller does, a submarine may move forward at lower speed. Water jet motors 4 and 9 may reach speed easily up to 200 m/s, when forced up to 300 m/s, at disc or smaller ellipsoid submarines. At huge ellipsoids for transport of heavy cargo they may reach about 100 m/s and when force even more. When traveling on water, speeds are as for vessels of the same shape and speed. At a part of a vessel determined as a rear one, as in disc 2 it is a circle and at ellipsoid 1 axial- symmetric peaks, water jet motors 4 from this group are connected by adequate hydrodynamic supports 5 through paneling to the submarine frame. As a rule, the position of a motor 4 is at vertical touching the submarine edge and at depth of its bottom point. The position of water jet motors 9 is at rear under submarine floor. It is clear that water jet motors from group 9 are used only when the submarine is under water, and from group 4 they are used also when in or at water. In this way, reactive force of thrust of water jet motors R_vm is transferred to the frame of submarine approximately at height of special stabilizer. This achieves approximately same level of activity directions of thrust force and travel resistance F_v, The torque of thrust force of the motor in the point of lining to a frame is balanced by the torque of submarine weight. In that case a submarine remains in horizontal position. The position of water jet motors 4 under the smallest bottom point of submarine is an important for travel over the water surface at high speed, when, practically, a water line touches the bottom point, and they should remain in water. A submarine moves then at the same speeds as in water, but with significantly less spent energy (theoretically half of it). Another group of water jet motors with double action of jets 10 are positioned around the edge of disc 2 or ellipsoid 1 submarine and with an axis in vertical direction. AS a rule, in this group there are smaller water jet motors, from 4 to 16, but even more. They are used for vertical mobility of submarine under water. Depending on the activity direction of the jets of these water jet motors, the submarine moves vertically downward or upward. In this way it may change deptli very fast when traveling or standing still, i.e. it may immerse or surface. Total thrust force of these motors should be higher then a thrust force of water to the submarine in order to move downward. When it accomplishes desired depth, and if it stays there for a while, water is pumped into the weight tanks. If a submarine is supposed to change depth constantly, this is not necessary. When moving upward the situation is more convenient because the forces directions are the same. Stabilization may be done by water jet motors from this group 10, as described above on submarine stabilization. A group of water jet motors with double action of jets 6 for maneuver and forward travel is under submarine bottom at the middle of the length, a half of it is on the left and another of the right of x axis as moving direction. As a rule, this group comprises an even number of smaller water jet motors with double activity of jets. It is used first of all to maneuver a submarine in water and on it. When all motors of this group operate simultaneously with jet activity in the same direction, submarine moves forward or reverse. When only one half of motors operate, submarine moves in larger arch and when both halves operate, but at opposite jet activity, submarine turns in the spot around a vertical axis. At submarine forward travel, this group is used as an additional to increase speeds and then all jets are in the same action direction. When, at travel, jets of this group act in opposite direction from travel direction, the submarine is stopped abruptly. Water jet motors from this group 6 are linked to the submarine frame by hydrodynamic supports 7 under the lowest point, and at depth as water jet motors for forward travel. Special group of motors 8 is made of the ones positioned at the middle of the submarine width, and left and right from transversal, y axis. It comprises an even number of water jet motors with double action of jet. They are fitted at submarines for special purposes, to be suddenly moved aside and not to change travel direction. It is achieved in travel and in standing still in water and on water. They are situated as previous group of motors 6 and they may be used for maneuver in horizontal flat. At ball submarine, as a rule, there are two water jet motors with double activity of jet at the sides and at height under the floor for horizontal travel, and there are four alike for vertical travel. This is sufficient number of engines when such submarine is used for people rescue or for research of sea bottom. In practice, water jet motors from several groups are used simultaneously to achieve desired motion and classic sterns are not necessary. From this description it may be seen that maneuver potentials of disc and ellipsoid submarines are extraordinary large for traveling in or on water. High voltage and higher operating frequency electricity is needed for operation of water jet motors. It is generated by corresponding generators in submarine. For their initiation steam or gas turbines and fast diesel engines in direct connection, are used. For steam turbines, water steam is made in boilers on liquid or gas fuel, but best in nuclear reactors. In near future, necessary energy on these submarines will be made by plasma reactors to produce necessary energy. Nuclear and plasma reactors will allow submarine to be under water for as long as human physical psychical potentials allow it. Electricity generators are positioned, as a rule, in the middle of submarine width and length and at the bottom. Lowering of this equipment to the bottom lowers the gravity point of the ship, and it also contributes stability in all situations. Around these units and in special room batteries are located for submarines that may need them. Auxiliary equipment such as water trans-loading pumps, fire extinguishing pumps, auxiliary electro aggregates and others, air ventilation and renewal units and air pressure keeping units is defined and distributed depending on submarine size and purpose, as well as on diving depth and speed by a designer. Measuring, governing, navigation and control equipment also depends on submarine size and purpose i.e. on fitted basic and auxiliary equipment. These modern submarines should have corresponding telecommunication equipment and basic are units for audio and video link, and very sensitive radars and sonar. Submarines that transport people and cargo must have adequate regulations and they must be registered according to current rules of associations for classification and registration of vessels.

INVENTION INDUSTRIAL OR OTHER APPLICATION Description clearly shows application of ellipsoid 1, disc 2 or ball submarines in water traffic for human and cargo transport under water. It is new large step in underwater equipment building development. For production of submarines according to this invention, current equipment in shipyards is sufficient. Also, for design of these submarines does not require knowledge which is not in use up to now. In fact, this is applied engineering which needs current knowledge in the branch of engineering or electrical engineering for this field. Up to now submarines were mostly used for military purposes and some for underwater research. This new submarine widens their use both for current purpose and for transport of very heavy cargo for long distances by shortest paths between the points on the Earth, for transport of passengers, for tourist picnics under water and for sport. It is only necessary to match regulations of society for classification and registration of ships and submarines. For closer study of some potential of disc and ellipsoid submarine some calculating parameters are given for some of them. Ellipsoid Submarine-cargo
