Magnetic artillery is a kind of advanced weaponry utilizing electromagnetic force to be launched by shell, utilize the active force of electromagnetic field to be gone out by pellet injection, in the development plan of following weapon, it has become more and more part and parcel, it is reported, the electromagnetic railgun of American R & D in trial fire once by bullet with very fast directive 200 kilometers of outer targets of velocity of sound 5 times, range is 10 times of naval's conventional weapon, and destructive power is surprising.

The general principle of magnetic artillery is famous Faraday's electromagnetic induction law, magnetic artillery classification common at present has railgun, coilgun, electrothermal gun and reclosing big gun etc. several, wherein railgun is the modal style of magnetic artillery, it is made up of two parallel long straight guides, the less slide block of a quality is placed as bullet between guide rail, when two rail access power supplys, powerful electric current flows into from a guide rail, when slide block flows back to from another guide rail, high-intensity magnetic field is produced between two guide levels, alive slide block is under the effect of Ampere force, and bullet can penetrate with very large speed.

Coilgun works according to the interactional principle in magnetic field between hot-wire coil, when passing into alternating current in accelerating coil, the alternating magnetic field produced will produce induced-current in bullet coil, the magnetic field of faradic magnetic field and accelerating coil electric current interacts, generate an electromagnetic field power, make bullet accelerated motion and launch, coilgun is of a great variety, two large classes can be divided into: one is the coilgun having direct electrical communication between two coils, two is two coils coilguns without direct electrical communication, have between two coils in the coilgun of direct electrical communication, commonly brush-commutated spiral winding big gun, also helical guideway big gun is, this brush-commutated shortcoming is to slidingly contact and rub, cause velocity of shot can not have larger raising, in order to overcome this shortcoming, there is brushless spiral winding big gun, two coils are without direct electrical communication, need not be brush-commutated between coil, drive coil and bullet coil respectively have oneself current source, general bullet coil current is less than drive coil electric current, feature is that the electric current of bullet coil makes bullet coil oneself induct out because drive coil curent change causes flux change, because the electric current at bullet coil internal induction is reverse, so only there is the driving force of repulsion mode in pulse induction coilgun, bullet coil can also form multistage pulses Induction Coil Gun by multiple single-stage coil tandem.

No matter be railgun or coilgun, substantially the driving force of single repulsion mode can only all be there is, indivedual mode that simultaneously there is repulsive force and tractive force also realizes with two coils, need the length and the volume that increase bullet, so when magnetic field is strong not, wanting to improve acceleration capacity just can only allow shell pass through enough large electric current, so just create the troubles such as big current heating and barrel ablation, and the electric current flowing through bullet all can not exceed the electric current of guide rail or drive coil, the bullet of Induction Coil Gun is owing to being induction generation current, so also can eddy current be produced, generate heat more serious, and owing to being alternating current in drive coil, the magnetic field of bullet itself also changes at any time, so be difficult to apply repulsive force and tractive force to bullet simultaneously, and there is the shortcoming slidingly contacting and rub especially in brush-commutated spiral winding big gun, this just causes velocity of shot can not have larger raising.

Also has the form such as electrothermal gun, reclosing big gun in addition, but as a whole, most importantly various magnetic artillery mode will solve how for bullet is powered and allow it produce larger electromagnetic force to greatest extent and finally obtain larger emission rate, and the efficiency done work to bullet in transmitter magnetic field how.

Contrast accompanying drawing 1 and circuit diagram accompanying drawing 10 and accompanying drawing 11 below, a kind of operation principle of the electromagnetic launchers with annular connector be described with three instantiations:

Example 1, explanation is launched portion by bullet 3, bullet coil 4, shell case 5 forms, situation about being combined into one with soft cable 1 and two annular connectors 2 being fixed on two ends: for convenience of description, bullet coil 4 in example and all transmitting tube coils 8 around to all consistent, when having two annular connectors 2, with bullet 3 grafting be called the first annular connector, what be stuck in shell case 5 bottom opening is the second annular connector, and in order 100 are numbered for multiple photoelectric controllers 7 respectively, 101, 102, corresponding electromagnetic relay 9 is numbered 200, 201, 202, corresponding transmitting tube coil 8 is numbered 300, 301, 302, as shown in Figure 9, for the ease of difference, weak control circuit portions in phantom in circuit diagram accompanying drawing 10 and accompanying drawing 11 represents, and eliminate the circuit of the light emitting diode part of photoelectric controller 7, the situation controlling single transmitting tube coil 8 due to single electromagnetic relay 9 is very simple, so be only described to control two in instances, during use, first close master switch, whole transmitter is made to be in preparation state, the bullet 3 namely portion of being launched is combined into one by artificial or mechanical mechanism, bullet coil 4, soft cable 1 and two the annular connectors 2 being fixed on two ends of shell case 5 and inside are placed on the transmitting site of transmitting tube 6, mobile foundation 15 moves forward along the guide rail on fixed pedestal 16 promotes comprehensively in the front port of transmitting tube 6 by the portion of being launched, outer bottom shell case 5 is launched after pipe 6 blocks, due to striker socket 11 that mobile foundation 15 is fixing be above protrude and the second annular connector bottom position positive alignment shell case 5, so striker socket 11 is just by the second annular connector jacking shell case of being stuck in shell case 5 bottom opening 5, simultaneously, because bullet relay 10 is normally closed switch, the circuit part that after master switch closes, it controls is in "on" position, so the striker coil 12 be fixed on striker socket 11 is switched on light current power supply 13 generation current and produces magnetic field, this magnetic field makes striker socket 11 also be with to be magnetic and firmly to be adsorbed by the second annular connector and corresponding electrode is connected, bullet relay 10 also makes the two poles of the earth of striker socket 11 connect the both positive and negative polarity of forceful electric power power supply 14 respectively simultaneously, circuit is made to be in "on" position, because the first annular connector is with appropriate magnetic, be adsorbed on the bottom of bullet 3, also related electrode also close contact is made, so whole circuit forms a complete loop, electric current flow through route as shown in Figure 6, flow through respectively: the positive pole of forceful electric power power supply 14, a contact of bullet relay 10, the internal electrode of striker socket 11, the target of the second annular connector, a wire of soft cable 1, the target of the first annular connector, circular structural metal pole piece in the middle of bullet 3, bullet coil 4, the structural metal pole piece of bullet 3 outer annular, the outer annular electrode of the first annular connector, another root wire of soft cable 1, the outer annular electrode of the second annular connector, the external electrode of striker socket 11, another contact of bullet relay 10, the negative pole of forceful electric power power supply 14, whole circuit makes bullet coil 4 produce magnetic field, due to the iron core that bullet 3 is also bullet coil 4 simultaneously, so this magnetic field can be reinforced and be applied on bullet 3 together, and the whole portion that is launched is when being pushed into transmitting tube 6, the face of cylinder of bullet 3 is just close to the position of first photoelectric controller 100 installed in transmitting tube 6 perforation, interlock circuit connects as shown in Figure 10, the light that the light emitting diode of photoelectric controller 100 sends is reflexed on light-sensitive element by the face of cylinder of bullet 3, it is such as photo resistance, electric current is had to pass through in the coil of the electromagnetic relay 200 making it control, the magnetic field produced makes contact switch close, the transmitting tube coil 300 and 301 it controlled is connected with the both positive and negative polarity of forceful electric power power supply 14 respectively, and make the direction of the sense of current of the transmitting tube coil 300 being positioned at bullet 3 afterbody and bullet coil 4 contrary, and the sense of current being positioned at the transmitting tube coil 301 of bullet 3 head is identical with the direction of bullet coil 4, like this due to coil around to all consistent, transmitting tube coil 300 will give bullet coil 4 together with bullet 3 one thrust forward, transmitting tube coil 301 then can give their attractions forward, under the effect of two power, bullet coil 4 departs from shell case 5 together with bullet 3 and travels forward along transmitting tube 6 inwall, first annular connector also firmly adsorbs and travels forward together by the high-intensity magnetic field that bullet coil 4 produces simultaneously, and the soft cable 1 be fixed in the above also is pulled to travel forward, coil the soft cable 1 placed just to be pulled open in turn, make second of the other end the annular connector can not under tension, because in this example, an electromagnetic relay 9 controls two transmitting tube coils 8, so the spacing of the perforate of transmitting tube 6 will be a bit larger tham the face of cylinder length of bullet 3, bullet 3 moves forward to the face of cylinder when leaving photoelectric controller 100, the light that the light emitting diode of photoelectric controller 100 sends can not be reflected on light-sensitive element, current interruptions in the coil of the electromagnetic relay 200 that light-sensitive element controls, thus the contact switch of electromagnetic relay 200 is disconnected, transmitting tube coil 300 and 301 current interruptions that it controls also makes the magnetic field dissipate of generation, bullet 3 moves forward due to inertia, when being close to the position of second photoelectric controller 101 on the face of cylinder, interlock circuit connects as shown in Figure 11, similar to photoelectric controller 100, transmitting tube coil 301 and 302 generation current that photoelectric controller 101 makes electromagnetic relay 201 control, and make the direction of the sense of current of the transmitting tube coil 301 being positioned at bullet 3 afterbody and bullet coil 4 contrary, what produce is repulsive force, and the sense of current being positioned at the transmitting tube coil 302 of bullet 3 head is identical with the direction of bullet coil 4, what produce is attraction, like this under the amalgamation of two power, bullet coil 4 obtains reinforcing together with bullet 3 and moves forward, the maximum change of this process one is that the sense of current of transmitting tube coil 301 changes, also from attraction, thrust is become to the active force of bullet 3, before and after twice to its active force, service efficiency is higher, under equal conditions, the acceleration that bullet 3 obtains is larger, such bullet 3 continues constantly to repeat this process forward together with bullet coil 4, the very high speed of final acquisition is moved to the mouth of pipe of transmitting tube 6, when arrival is in a photoelectric controller 7 of nozzle position, this photoelectric controller 7 also controls normally closed bullet relay 10, the pulse current produced makes the contact switch of bullet relay 10 disconnect, the whole circuit from striker socket 11 to bullet coil 4 connected with it just no longer includes electric current to be passed through, bullet 3 is together with the magnetic field dissipate of bullet coil 4, just its external force of advancing of effect is lost by its first annular connector held, but because effect of inertia also can move forward, simultaneously, dead circuit also makes the current interruptions of striker coil 12 and loses magnetism, the absorption affinity of striker socket 11 to the second annular connector also disappears, like this, the limitation of length is arrived at soft cable 1, the proal first annular connector of inertia just hauls the soft cable 1 of expansion and makes the second annular connector pull out striker socket 11 simultaneously, then fly out transmitting tube 6 together, second annular connector is pulled away from hourly velocity, and to become connector annular with first from zero consistent, period it also can be powerful to the first annular connector one reaction force, the first annular connector and bullet 3 is impelled to depart from, make it can not affect the subsequent flights of bullet 3 again, long soft cable 1 is subject to certain resistance in atmosphere, just can drop together after a period of time, all right recycling under certain condition, final bullet 3 then flies to required target as operate portions together with bullet coil 4, after this emission process is complete, the mobile foundation 15 of emission part to be dropped back original position along the guide rail of fixed pedestal 16 together with the striker socket 11 be fixed in the above and striker coil 12, and the contact switch of bullet relay 10 recovers closed after bullet 3 flies out transmitting tube 6, wait be launched portion in place after carry out again the next one circulation, in this example, although the first annular connector has certain magnetic property to be adsorbed on bottom bullet 3, but likely can come off in transportation, just this problem can be solved so the structure of shell case 5 slightly designed to improve, as shown in Figure 8, in addition, in the application of reality, the mode that can also be controlled the quantity of transmitting tube coil 8 by the density or increase electromagnetic relay 9 increasing photoelectric controller 7 and transmitting tube coil 8 improves the emission rate of bullet 3, and often need to stagger to two transmitting tube coils 8 that bullet 3 applies active force simultaneously, as the 1st and the 4th, 2nd and the 5th, 3rd with the 6th etc., when the first annular connector there being coil, can be connected with light current power supply 13 by other wire of soft cable 1 and relay switch, it is made to produce a magnetic field contrary with bullet coil 4 to be pushed away in last separation phase.

Example 2, the situation that the portion of being launched and soft cable 1 and the annular connector 2 being fixed on one end are combined into one is described: this example and example 1 basically identical, just annular for first bottom bullet 3 in example 1 connector is removed, during work, electric current directly arrives bullet coil 4 by wire, whole process is substantially constant, just in the end bullet 3 fly out the mouth of pipe of transmitting tube 6 time, soft cable 1 and the annular connector 2 being fixed on one end can not be separated with bullet 3, several parts target together, the advantage of this example has lacked parts, more simple and reliable in technique, shortcoming is that soft cable 1 can increase air drag and affects speed, this example also has other shortcoming, it not preferred version.

Example 3, contrast accompanying drawing 12 below and illustrate that the portion of being launched only is made up of bullet 3 and bullet coil 4, one end of soft cable 1 is fixed on the situation on fixed pedestal 16: compared with example 1, this example eliminates striker socket 11, striker coil 12 and shell case 5, and only have an annular connector, the portion that is launched only is made up of bullet 3 and bullet coil 4, structure is simpler, during transmitting, bullet 3 is in the transmitting site of transmitting tube 6, one end that soft cable 1 is fixed on fixed pedestal 16 is in on-state by bullet relay 10 and forceful electric power power supply 14, the other end connects annular connector 2 through the perforation of mobile foundation 15, annular connector 2 is embedded in the locating slot of mobile foundation 15 simultaneously, can accurately navigate on the socket bottom bullet 3, mobile foundation 15 drives annular connector 2 to travel forward along the track of fixed pedestal 16, while bullet 3 is advanced in transmitting tube 6, annular connector 2 is injected the socket bottom bullet 3 and connects circuit, make bullet coil 4 generation current and and then produce magnetic field, then its photo-electric control process is identical with the related link of motion process and example 1, and when in the end stage bullet 3 and bullet coil 4 move to the controlled power-off of nozzle position of transmitting tube 6 and depart from annular connector 2, because one end of soft cable 1 is fixed on fixed pedestal 16 in this example, its length limits annular connector 2 and can not fly transmitting tube 6, stay in transmitting tube 6 so annular connector 2 is just held by brute force, target is continued together with bullet 3 and the annular connector 2 of bullet coil 4 disengaging, after having launched, soft cable 1 can be pulled by the perforation of mobile foundation 15 and make annular connector 2 be automatically embedded in detent, then prepare to launch next time, the action retracted can be completed by manpower, also can increase design one recovering mechanism automatically to complete, as shown in Figure 12, one can be increased and be fixed on fixed mechanism 21 on fixed pedestal 16 and travel mechanism 22, be respectively equipped with rotating wheel above, soft cable 1 passes in the middle of two wheels, when reclaiming soft cable 1, the wheel of travel mechanism 22 is close to the wheel of fixed mechanism 21 downwards and rotates with the direction of arrow in scheming under motor drives, just bulk storage is recovered to fixed pedestal 16 rear portion by the soft cable 1 that two wheels extrude, when launching, fixed mechanism 21 and travel mechanism 22 are separately, soft cable 1 is in completely without restrained condition, to make bullet 3 can not be subject to resistance in the process hauling the advance of soft cable 1, because the mode reclaimed can have a variety of, and dispensable technical characteristic, so do not enumerated and requirement concrete mode, this example economic benefit is higher, the portion of being launched that bullet 3 and bullet coil 4 form is the most minimum, but require higher to the pull resistance of soft cable 1, and the annular connector 2 advanced at utmost speed also can cause certain impact to fixed pedestal 16.

All technical schemes can also be used for product for civilian use field, various shape object can be launched, can be combined with military or civilian unmanned plane, unmanned plane is transmitted into away with certain speed, make it can have the more hang time in target spatial domain, the technical scheme of example 3 can also be used on the Electromagnetical ejector of aircraft carrier, and do not need annular connector, only need impose forward current to bullet just can realize launching reinforcing, impose reversing the current then can buffer deceleration to stopping or even turning back to original position, simple and convenient and fast.

Best embodiment of the present utility model is illustrated, and the various change made by those of ordinary skill in the art or remodeling all can not depart from scope of the present utility model.
