Description
Technical field
This utility model belongs to electromagnetic propulsion technical field, is that a kind of many bullets electromagnetism carries bullet smooth bore.
Background technology
Magnetic resistance type coilgun makes the magnetic resistance change rate of a kind of ferromagnetic magnetic circuit utilizing coil attract iron core motion to accelerate the Electromagnetic Propulsion of iron core bullet.It has some differences with common coilgun, one is that its bullet is a monoblock ferromagnetic material, and accelerated is not bullet coil or tubulose bullet, its two be in gun system introduce ferromagnetic material, although the performance of big gun is had some to affect by this, play efficiency higher than air core coil big gun.But magnetic resistance type coilgun can only launch one piece of bullet every time.
Magnetic resistance type coilgun is made up of the yoke iron core of a series of solenoid drive coil and ferromagnetic material.So-called magnetic resistance, refers to stop magnetic circuit around coil to set up the resistance of magnetic flux.In coil lumen, place ferromagnetic material can reduce magnetic resistance.When iron core motion is that the magnetic resistance of the magnetic circuit of wound coil will change, the most just iron core bullet is produced active force.The pcrmeability that the iron core of ferromagnetic material is bigger than the air replaced by it.When iron core moves to hub of a spool, magnetic flux is relatively easy to form and passes through, this is because the air-gap of magnetic circuit diminishes, the magnetic resistance of magnetic circuit also diminishes, and now the active force to iron core is also minimum.When iron core is removed from hub of a spool, iron core magnetic force forward was originally drawn to now become to draw iron core backward.
Utility model content
This utility model is intended to solve to a certain extent the above deficiency of prior art, can only launch the limitation of one piece of bullet for original magnetic resistance type coilgun, proposes a kind of new many bullets electromagnetic launch system.
This utility model realizes goal of the invention technical solution: a kind of many bullets electromagnetic launch system, mainly by having transmitting tube 2 and being placed in the magnetic resistance type coilgun mechanism driving coil 1 to be main body of transmitting tube outer wall and form.It is provided with one in transmitting tube 2 and can carry the load bullet smooth bore 1 launching many pieces of bullets simultaneously；Drive coil to be placed in transmitting tube sidewall, can back and forth deliver bullet load bullet smooth bore and be placed in transmitting tube.
The described bullet smooth bore 1 that carries is the symmetrical cylindrical appliance with multiple load shell hole 8.
The described bullet smooth bore 1 that carries uses the material of high permeability low conductivity or composite material structure to form.
Described driving coil can be normal conductor coil can also be superconducting coil.
It is provided with one in transmitting tube 2 and can carry the load bullet smooth bore launching many pieces of bullets simultaneously；Utilize impulse circuit to driving coil to provide a great pulse current, in ferromagnetic circuit, magnetic field is produced with this, the magnetic resistance change rate attraction utilizing ferromagnetic magnetic circuit is sent out bullet device motion and is accelerated to send out bullet device and a bullet, finally reach bullet fly out gun tube send out play device then stop in gun tube, bullet device will be sent out by traction apparatus again and retract original place, this so can be utilized to carry and to play smooth bore repetitious transmitting bullet, improve tradition electromagnetism recommendation apparatus and once can only launch the limitation of one piece of bullet.
Use the discharger of the present invention, in the case of can accomplishing to utilize impulse circuit to driving coil with electric current, launch the effect of many pieces of bullets simultaneously, and this emission process can be repeated several times.
Accompanying drawing explanation
Fig. 1 is the broken section of the present invention.
Fig. 2 carries the side view playing smooth bore.
Fig. 3 gives the external circuit driving coil to provide pulse current.
In figure: 1 is to carry to play smooth bore, and 2 is transmitting tube, and 3 is to drive coil, and 4 is fixing device, and 5 is base plate, and 7 is bullet, and 8 is to carry shell hole.
Detailed description of the invention
The present invention is described further with detailed description of the invention below in conjunction with the accompanying drawings.
Propulsion plant as Figure 1-Figure 2, mainly it is made up of load bullet smooth bore, bullet, driving coil, transmitting tube, because traction apparatus and external circuits are not the key components of the present invention, therefore it has been merely given as the circuit diagram (Fig. 3) of impulse circuit, and in invention device, eliminate wiring diagram and the traction apparatus of external circuit.nullFirst，When carrying bullet smooth bore 1 and being in initial transmitting position，Give and carry the upper bullet of hole filling played in smooth bore 1，After ready，Given by external circuit again and drive coil to be passed through with pulse current (this pulse current width is for from carrying bullet smooth bore setting in motion to the last stop motion)，Load bullet smooth bore 1 just can be made to accelerate together with bullet，Speed maximum when smooth bore 1 arrives driving coil centre position is played when carrying，Occur slowing down until speed is kept to zero due to suction afterwards，The continuous current circuit electric discharge that diode forms is begun through when smooth bore speed is kept to zero when carrying to play，Electric current now is less，Persistent period short and smaller suction can be produced，Load bullet smooth bore is made the most slowly to move，But have frictional force effect owing to carrying to play between smooth bore and gun tube，Carry and play that smooth bore is the most static is parked in gun tube，Bullet then can play after smooth bore 1 reach maximal rate owing to inertia flies out transmitting tube carrying.After completing primary emission, carry bullet smooth bore 1 and can be parked in transmitting tube 2, then pulled it back initial position by mechanical traction device, to launch next time.
Embodiment
The coil of the cylindrical, copper wire coiling using section radius to be 2mm, coil is divided into 10 layers, every layer of wire around 25 circles.Carrying and play smooth bore and be made up of ferrite, its structure is the cylinder that 5 holes are drawn in inside, size be radius be 5cm, a length of 10cm, and the structure in 5 holes is cylinder, its size be radius be 5mm, a length of 30mm.Inside 5 holes load on 5 pieces of bullets, material is aluminium oxide, and structure is cylinder, size be radius be 4.5mm, a length of 30mm.The distance from bottom carrying the distance from bottom coil playing smooth bore is 22cm.In Fig. 3 circuit, electric capacity is to be respectively charged in 10kv by the electric capacity of 10 1000uf, make switch close by control afterwards to discharge to coil (i.e. inductance L in Fig. 3), cross when coil will decelerate to zero at load bullet smooth bore and controlled switch-off, electric current in coil is made to be discharged by the continuous current circuit of diode, when electric current is reduced to zero, carry bullet smooth bore also slowing down is zero.Can be measured by simulation calculation and carry that to play the maximal rate accelerated together with bullet of smooth bore be 339 metre per second (m/s)s, bullet no longer stress flies out gun tube with inertia afterwards, its muzzle velocity i.e. maximal rate 339 metre per second (m/s), carry bullet smooth bore then to be slowed down by suction until speed is zero, finally it is still in gun tube, its move distance is 44cm, is i.e. 22cm by the move distance after coil.
Use the basic structure of the present invention; but there is multiple equal conversion in actual enforcement; and the selection carrying the structure and material playing smooth bore and bullet has multiformity; in every case it is technical scheme and the design thereof utilizing reluctance transition to accelerate to launch many pieces of bullets; equivalent and conversion in addition, is all considered to belong to the scope of the claims of the present invention.
