Abstract
An electromagnetic propellant-less thruster comprises at least one electric current transmission line 5a, a means of producing electrical pulses (1, 2, 4a, 4b in figure 1) of short predetermined duration and predetermined rate, and an electromagnetic shielding means forming a plurality of volumes, each volume containing at least one segment / section of the electric current transmission line, the shielding means preventing electromagnetic fields in one volume interacting with electric current in different volumes. Ideally, the arrangement comprises two superconducting parallel wires 5a, 5b located within the shielding means 6a, 6b, while the electric pulse duration, and the duration between the pulses in the first and second wires are of picosecond duration. The electromagnetic thruster claims to operate by making one wire react off the field created by the other wire thereby creating a force vector, but wherein the field created by the second wire does not does not affect the first wire. The device does not require propellant, only electrical energy.
Description
Description
Propellant less electromagnetic thruster
Technical Field
1] Propellant less electromagnetic thruster is an apparatus for producing thrust for propelling any vehicle using electromagnetic interactions without the use of a propellant gas.
Background Art
[00021 Current commercial electromagnetic thrusters use an ion beam in order produce thrust. This will require a propellant gas. The disadvantage of this type of thrusters is that when the propellant runs out the thruster's life comes to an end.
3] US5197279 is a similar patent based in the same principle but the design is complicated, most of the features described can be eliminated and the efficiency is questionable. For example the author disciosers "forward and rearward electromagnetic field generators", these are ordinary coils, with electromagnetic reflecting walls and hollow housing. Our disclosures is based in a novel arrangement of planar wire (electric current transmission lines) which can operate with one or two electric current transmission lines and does not require hollow housing and reflecting walls.
4] Also the "field generator means" are coils so in order to work the current has to switch in milliseconds or grater range witch means that the two coils have to be placed at a substantial distance to each other having as a result reduced efficiency since the force decrease in the inverse square of distance. In our disclosure the current transmission lines do not form a coil but are planar thin lines, like the one you find in printed circuits, positioned in a novel way (Figures 2 & 4) and the electric pulses are of picoseconds duration, so planar transmission lines can be placed very close to each other. Further more the shielding arrangement "magnetic bamer" described shield the complete coils arrangement from the outside areas and works as a wave guide from one coil to the other. Our disdosed arrangement of novel electromagnetic shielding is an arrangement of small shielding segments defining small shielding volumes containing at least one segment of each transmission lines. The purpose is to avoid electromagnetic waves produces from part of the electric current transmission lines to reach and interact with some other areas of the opposite transmission line.
5] FRI 586195 also based in the same first principle, the time required for electromagnetic wave to travel from one coil to the other. Although the author does not specify the pulse duration, at time of invention picoseconds duration pulses could not be produced, the efficiency of this device of picoseconds or even milliseconds pulses at high repetition rates is questionably. Further more the author specifies that electric current is alternate. Even if we accept that the device can produce thrust with high frequency alternative current, without small shielding segments (6a,6b) (as described in our discloser) the total net force will be negligible close to zero. Finally the author describes "at least two active drivers". Our disclosure can operate with one as well as with two active driver electric current transmission lines. Also the novel arrangement, disclosed below, of the electric current transmission lines (figures 2 & 4) is important for producing thrust in connection with the shielding segments.
6] FR2036646 claims alternative current flowing threw two magnetic generating coils. As described above we claim an apparatus that uses picoseconds electric current pulses producing electric field interacting within same transmission line or with second, positioned in a novel way.
Also shielding volumes as described above are not included in the
description of the device.
7] Other propellant-less electromagnetic thrusters are available like solar sail, electrodynamics tether, momentum exchange tethers, coupled electrodynamics, electrostatic prolusion systems ESNPAT/466 (filed in France as no. 0204336).
8] Solar sails can be effective but require vast sails of ultra light material.
Solar sail materials are still under development for optimization.
9] Electromagnetic tethers require a magnetic field of a planet in order to operate. So since a space craft has left the magnetic field of a planet it can no longer accelerate and cannot change direction if needed.
0] Momentum exchange tethers require a gravitational field in order to operate. So they have the same disadvantage with electromagnetic tethers.
[00111 An electromagnetic thruster is an apparatus witch requires no external magnetic or gravitational field. Also current technologies are sufficient to operate subject apparatus. It does not require exotic materials like the solar sail. It is suitable for deep space missions since it can provide thrust as long as electrical power can be supplied to the thrusters. By doing this high speeds can be achieved by continues run of the thrusters.
Disclosure of Invention
[00121 Electromagnetic thruster comprises of a laser (see figure 1) used as triggering device (1), a set of fibber optics (2) optical pulse delay apparatus (3), two picoseconds photoconductive switching devices (4a,4b) that can switch at very high repetition rates MHz, GHz or even 1Hz range producing electric pulses of picoseconds duration, two planar electric current transmission lines (5a,5b) positioned opposite, preferably parallel, to each other (For linear arrangement see figure 1, for spiral arrangement see cross section of spiral arrangement figure 4). Each spiral turn or set of two linear electric current transmission lines is separated from the next one by electromagnetic shielding material (6a). Additionally electromagnetic shielding materials are positioned between electric current transmission lines (5a) -(5b), preferably normal to (6a). Plurality of small void spaces are generated wherein electromagnetic waves produced by segments of the electric current transmission lines are confined within this sealed volumes and do not interact with other unwanted transmission line segments.
3] Also the shielded volumes have to be large enough in order to allow electromagnetic field produced from the segments of the electric current transmission lines (5a,5b), contained within same shielded volumes, to reach each other. Simulation showed that if you place the parallel shielding material (6a) at a distance to electric current transmission lines, much smaller than the separation distance between (5a,5b), then electromagnetic field intensity and efficiency drops dramatically. These electromagnetic isolated volumes can either be completely dosed by shielded materials (6a, 6b) or can be partly closed. In the case of partly closed, the shielded materials (6b) has to be large. Large enough in order the electromagnetic field produced from a segment within one volume when reach segment within other shielded volume to be negligible. Figure 4 describes partly closed electromagnetic shielded volumes, where figure describes a series of closed electromagnetic shielded volumes.
4] For increasing the electromagnetic field produced between the source planar electric current transmission line (5a) and the thrust transmission line (5b) ferromagnetic material (7), or any other material that enhances the magnetic field (which has low attenuation properties for the electric pulses) can be placed inside the void space formed by the shielding arrangement (6a,6b) between the electric current transmission lines as shown in figures 2,3,4,5. It can be also (7) any material that reduces the propagation speed of electromagnetic waves. By doing so, the two transmission lines can be placed closer to each other and produce larger forces. In this case the material (7) is recommended to occupy the complete void volume created by the electromagnetic shielded materials (6a,6b). Also for manufacturing purposes the electric current transmission lines can be supported on the surface or inside cavities created in material (7). Cavities must be created if material (7) occupies totally the void space defined by (6a,6b) in order electric current transmission lines to pass through (7).
5] The material of the electric current transmission lines can be any conductor, like copper, or preferably superconducting materials. Since it is easier to switch small voltages at very high speeds, by using superconducting coils high amperes can be passed threw long coils even at low voltage potential deference. The superconducting spiral transmission line can be manufactured with the method of lithography on the surface of a base plate or wafer (9) (figure 4), in the same way printed circuits boards and microprocessors are manufactured. Also picoseconds pulses can propagate longer distances in superconducting materials.
6] Currently standard superconducting cables come to thin rectangular filaments sizes, witch makes them very difficult to form a spiral shape. So other shapes have to be used. For example as shown in figure 5 a set of two superconducting transmission lines of rectangular cross section placed parallel to each other with a plurality of "U" shapes turns can be used. In every "U" turn of the complete set of electric current transmission lines (one set of two or more sets) has to be rotated by 180 degrees in order the force vector to have the same direction and not cancel out with the force vector of the superconducting transmission line segment before the U or Ii" turn. Also like other electric current transmission line shapes shielding boundaries (6b) have to be placed as discussed earlier between the transmission lines (5a,5b) in order to avoid unnecessary electromagnetic wave interactions. Also between each "U" turn a complete shielding boundary (6a) has to be placed or they have to be placed in grate distance that the electromagnetic field has been significantly been reduced.
10017] The length of the space defined by the shielding arrangement (6b) which includes a segment of each electric current transmission line depends from the duration of the pulse and the speed the electric pulse propagates within the transmission line. The length between two consecutive shielding materials (6b) has to be sufficient in order to accommodate one electric pulse at a time. This means that the width of the pulse should be preferably equal to the separation distance between two consecutive shielding materials (6b).
8] As the electric pulses propagate large distances dispersion phenomenon are present so the spacing between two consecutive shielded materials must take in to consideration this phenomenon at large distances.
9] The duration of each electric pulse preferably should be equal or less than the time the electromagnetic wave produced from the segment of the electric current transmission line to reach the parallel segment of second transmission line within same shielded volume.
0] If larger pulse duration is used then the device can work but bigger time delay between pulses propagating within deferent electric current transmission lines has to be used, to avoid unwanted interaction, having as a result a reduction in efficiency.
1] The electric pulse duration can be controlled by the duration of the laser pulse. The time the laser pulse excites the photoconductive switch.
2] The optical delay apparatus can be a set of reflecting mirrors with longer distance between them, longer fibber optic cable compared with optical fibber of the other photoconductor sensor so the laser pulse will have to travel longer distances or any other commercial available optical delay apparatus.
3] Alternative to commercial magnetic shielding materials a superconductor material can be used. Since superconductors are perfect shielding materials at low temperatures a cryogenic system will be required. Other good conducting material can be used like cooper instead. To avoid conducting electrical pulses threw the shielding material a thin insulation film has to be applied on the surface or to make sure that the shielding material does not come in contact with the coils that propagate the electric pulses. Otherwise insulation can be installed on the surface of the transmission lines (5a,5b).
4] Alternatively the triggering device, instead of a laser with a set of optical reflectors and the photoconductive switching devices, a high frequency signal produced by a signal generator such as high pressure gas switches, MOFSET or a number of MOFSETs switching together for higher current densities such as positioned in parallel, Q switches, In Plane Gates and other semiconductor switching apparatus can be used.
5] Also Josephson junction can be uses to create pulses of smaller than one picosecond duration.
6] As discussed above the electromagnetic propellant less thrusters can operate preferably with picoseconds duration pulses or less for increased efficiency. The devise can operate with larger pulses duration also, if the design specification requires it, but the two parallel parts of the electric current transmission line has to be positioned further apart so efficiency will be compromised. On the other hand pulses can travel longer distances and substantial electric currents can be switched.
Brief Description of Figures in the Drawings
7] Figure 1 is a complete general arrangement of the apparatus including all necessary items for the thrusters to work. This arrangement is set up with two deferent, parallel and linear electric current transmission lines (5a, 5b).
The arrangement of the electric pulses can be seen in this figure.
8] Figure 2 describes the arrangement of the electric current transmission line only, without the photoconductive switch and laser arrangement. As can be seen only one electric current transmission line is used to produce thrust. In this figure the description of segments and shielded volumes are presented witch same is applicable to all figures. Also a cross section view A-A' of the arrangement is presented.
9] Figure 3 describes the arrangement of electric current transmission line only. This arrangement is characterised from a junction in the electric current transmission line splitting the electric pulse. One leg of the junction is larger from the other leg. With this arrangement only one photoconductive switch is required. Also a cross section view A-A' of the arrangement is presented.
0] Figure 3b describes the same as figure 3 but with the deference of having electric current transmission lines of spiral shape.
1] Figure 4 is a cross section of spiral shape electric current transmission lines arrangement. General arrangement of spiral (5a,5b) only can be seen in figure 3b. The electromagnetic shielding materials (6a,6b) can be seen clearly. Also the wafer (9) were the spiral electric current transmission lines are positioned on it can be seen. The wafer (9) can be omitted if planar electric current transmission lines (5a,5b) are positioned on the surface of material (7). The spiral electric current transmission lines can be either two different ones, like the ones in figure 1, or the same as described in figure 3b.
2] Figure 5 is a cross section of two long, preferably superconducting planar, electric current transmission lines positioned in a specific way to produce thrust. The rotation of the lines of 180 degrees in every "U"tem is demonstrated.
3] In figures 2,3,4,5 material (7)is placed only between the electric current transmission lines for. Alternatively is more convenient, for manufacture purposes, the material (7) to occupy the complete void space defined from 8' electromagnetic shielded materials (6b) and (6a).
Best Mode for Carrying Out the Invention
4] A laser (1) produces a series of short optical pulses (fempto-seconds duration). The first optical pulse is travelling threw fibber optics (2) to the photo conducting switches (4a,4b). The optical pulse reaches photoconductive switch (4b) with a time delay in respect to switch (4a) since the optical signal passing threw an optical divider (3) travels longer distance (2b). These two optical signals with short time deference will produce two electrical signals with time delay to each other. This time delay of the electrical pulses can be preferably same or less than the time required for the electromagnetic waves produced from one electric current transmission line (5a) to reach electric current transmission line (5b).
5] In the event of larger time delays the device can work but reduced efficiency is likely if not all the length of the electric pulse interacts with electromagnetic wave and a smaller force will be produced.
6] So optical signal from laser (1) travelling through fibber optics (2) is reaching photoconductive switch (4a) at time "1' and through optical divider (3) travelling longer distance (2b) to photoconductive switch (4b) at time "I + a". This will produce two electrical picoseconds pulses with time deference tern. First electrical pulse travelling through the first segment of planar electric current transmission line (5a) as defined by the first shielded volume producing an electromagnetic wave propagating to all directions. Due to the shielding (6a,6b) the electromagnetic wave will be confined within this first shielded volume defined by (6a,6b) which includes segments of the two electric current transmission lines (5a,5b) and will not reach other parts of the transmission lines. This process is repeated for every optical pulse produced from the laser.
7] By the time the electromagnetic wave produced by the first electric pulse propagating through the first segment of electric current transmission line (5a) reaches the second electric current transmission line (5b), within the first shielded volume, the voltage of the electric pulse in the first segment of electric current transmission line (5b) positioned within same shielded volume will be at peak value, in the event of a square wave electric pulse or close its peak value in the event of Gaussian pulse. The electric pulse passing threw the first segment of transmission line (5b) as defined by the first shielded volume will interact with electromagnetic wave produced from first segment of electric current transmission line (5a) as defined by the same shielded volume and produce a force vertical to the direction of the magnetic field and the direction of electrical current. During the time electric pulse propagate threw the first segment within the first shielded volume in way of transmission line (5b) and the time required for the electromagnetic wave to propagate from electric current transmission line (5b) towards (5a) the electric pulse inside same shielded volume has propagated through transmission line (5a) completely to the next shielded volume.
8] As a result the electromagnetic wave produced by the first segment of electric current transmission line (5b) when roach the first segment of transmission line (5a) within same shielding volume will not find an electric pulse so a force of reverse direction will not be produced by transmission line (5a).
9] At same time electric current transmission line (5b) produces an electromagnetic wave propagating towards electric current transmission line (5a). Since the time required by the electromagnetic wave to travel from electric current transmission line (5b) to electric current transmission line (5a) is less than the separation distance between two consecutive pulses travelling within same electric current transmission line, then by the time electromagnetic wave reaches the electric current transmission line (5a) no current will be flowing through electric current transmission line (5a), within first segment. As a result no force will be produced by (5a) and a positive force will be produced only by electric current transmission line (5b).
0] The above process continues as the electric pulses travel through the electric current transmission lines and interacts with each others electromagnetic field within each shielding volumes. This process is repeated for every segment of the electric current transmission lines, as they are defined by the different shielded volumes, as electric pulses propagate through them.
[00411 The separation time of two consecutive pulses travelling within the same transmission line must be sufficient long in order to avoid unwanted interference from the electromagnetic waves produced by the previous or ahead pulses. A separation time between two consecutive pulses twice the time required for electromagnetic wave to propagate from one transmission line to the opposite plus the pulse duration, is a good approximation.
2] Longer time periods can be used if we need to consider reflection of electromagnetic waves from the walls of the (6a,6b).
Mode(s) for Carrying Out the Invention [0043] Alternative instead of having two or more parallel electric current transmission lines, the propellant less electromagnetic thruster can operate only with one electric current transmission line which will serve as source of electromagnetic field energy and as thrust electric current transmission line at same time. Some parts (5a) of the planar electric current transmission line are placed opposite, preferably parallel, to the other parts (5b) of the same planar transmission line as shown in figure (2). The arrangement could look like a series of "fl" shapes connected to the ends and of reverse direction.
[00441 Each set of two parallel parts (5a,5b) of electric current transmission line is separated completely from the next set by electromagnetic shielding material (6a).
5] Additionally shielding materials (6b) are positioned between all parallel parts of the planar electric current transmission lines, in such a way that small void spaces are generated wherein electromagnetic waves produced by segments of the planar lines propagate and are confined within these sealed volumes. Preferably the volumes are of cube or trapezium shape and these shielding materials are normal to (6a).
6] Also the length (8) of the wire that connects the two parallel parts of the planar electric current transmission lines works as calibrator. The length (8) will determine the time were the electric pulse will enter a segment of the electric current transmission line in respect to an electric pulse leaving the segment in the opposite (parallel) planar electric current transmission line, as both defined by the same shielding volume. In other words, the length (8) connecting the two parallel parts of the same planar electric current transmission line disposed within same shielded volumes, defines the "time delay" parameter as described in the previous section of "Best mode".
7] As mentioned earlier the distance between two parallel parts (5a,5b) within same shielded volume of the electric current transmission lines and the distance of two consecutive shielding segments (6b) also the duration and time delay between two consecutive pulses are all interconnected. All have to be of appropriate length or width and time duration in order electromagnetic waves produced by the pulse in the fist parallel part of the coil, within the first segment defined by the first shielded volume, reaches the opposite parallel part of the transmission line (5b) of the same shielding segment when the electric pulse is passing through it. At the same time electromagnetic waves produced by the second parallel part of the transmission line (5b) within same shielding volume must reach the first segment of the parallel part (5a) of the transmission line within the same shielded volume when there is no electric pulse through it.
8] Alternative the electric pulse can be split in to two pulses by a junction before entering the parallel parts (5a, 5b), as shown in (figure 3 & 3b). In this case the distance the electric pulse has to travel to reach the first shielded volume is greater in (5b) compared with the distance to reach (5a). As a result the pulse in 5b will have the required time delay in order the device to produce thrust, as discussed above.
9] Operation of aftemative modes [0050] A laser (1) produces short optical pulses (fempto-seconds duration). The optical pulses are travelling through a fibber optic (2) to a photo conducting switch (4).
1] This will produce electrical picoseconds pulses. (Figure 2) The device will start to produce thrust when the first electric pulse has travelled through the electric current transmission line (5a), through the calibration part of the electric current transmission line (8) and reached the first electromagnetic shielded segment through (5b). Our description will start from this point forward.
2] So electrical pulse travelling through the first segment as defined by the first shielded volume of the electric current transmission line (5a) producing an electromagnetic wave propagating to all directions. Due to the shielding (6a,6b) the electromagnetic wave will be confined within the first shielded volume and will not reach other parts of the transmission lines. (figure 2) [0053] By the time the electromagnetic wave produced by the planar transmission line (5a) reaches the opposite planar transmission line (5b), within the first shielded segment, the voltage in transmission line (5b) will be at peak value, in the event of a square wave electric pulse or close its peak value in the event of Gaussian pulse. The electric pulse passing through the first segment as defined by the first shielded volume, transmission line (5b) will interact with electromagnetic wave produced from the first segment of transmission line (5a) and produce a force vertical to the direction of the magnetic field and the direction of electrical pulse. During the time electric pulses propagate through the first segment in way of transmission line (5b) and the time required for the electromagnetic wave to propagate from (5b) towards (5a) the electric pulse inside same electromagnetic shielded segment volume has propagated through transmission line (5a) out of first shielded segment to the next shielded space.
4] As a result the electromagnetic wave produced by the first segment of transmission line (5b) when reach the first segment of transmission line (5a) within same shielding volume will not find an electric pulse so a force of reverse direction will not be produced by transmission line (5a).
5] This process is repeated for every segment of the planar transmission line as they are defined by the different shielding volumes as electric pulses propagate through them.
6] The separation time of two consecutive pulses travelling within the same electric current transmission line must be sufficient long in order to avoid unwanted interference from the electromagnetic waves produced by the previous or ahead pulses. A separation time between two consecutive 13/ pulses equal to the time required for electromagnetic wave to propagate from planar electric current transmission line (5a) to the opposite, parallel, transmission line (5b) is a good approximation. Longer time periods can be used if we need to consider reflection of electromagnetic waves from the walls of the (6a,6b).
10057] The selection which of the above different configuration can be used depends on the material selection and pulse duration. For example if a superconductor is used and the pulse duration is large, which corresponds to a frequency witch is much smaller than the energy gap frequency of the material then the pulse can propagate large distances and figures 2 and 5 can be used. If very short pulses are used then the two parallel transmission lines can be positioned much closer to each other but the propagation length of the electric pulse will be much less and figures 2,3,4 may be used.
8] In all above sections we described planar electric current transmission lines. The device can work also with normal round cable but is not recommended due to efficiency considerations.
9] Propellant less electromagnetic thruster can operate also with optical pulses of picoseconds duration if design parameters require it.Sub-fempto seconds optical pulses currently can not be produced efficiently. But device also can work with sub-femtosecond optical pulses if available.
[00601 All drawings have demonstrated arrangements were planar electric current transmission lines (5a,5b) are positioned in deferent planes. Alternatively planar transmission lines (5a,5b), material (7) and electromagnetic shielding materials (6a,6b) can be positioned in the same base plane (9), like printed circuit boards. It is recommended material (7) and electromagnetic shielded materials (6a,6b) to expand also to other parallel planes positioned at either sides of base plane (9).
(0061] All characteristics and alternative modes described in "Best mode" section which do not contradict with "alternative modes" are also applicable in this section. In this section mainly we outline the different characteristics between the two modes.
