Embodiment
[0018] A coil made of cylindrical copper wire with a cross-sectional radius of 2mm. The coil is divided into 10 layers, and each layer is wound with 25 turns of wire. The bullet-carrying smoothbore is made of ferrite, and its structure is a cylinder with 5 holes cut out inside. The size is 5cm in radius and 10cm in length. The structure of 5 holes is a cylinder with a radius of 5mm. The length is 30mm. Fill the 5 holes with 5 projectiles, the material is alumina, the structure is a cylinder, the size is 4.5mm in radius and 30mm in length. The distance between the bottom of the loading smoothbore and the bottom of the coil is 22 cm. image 3 The capacitor in the circuit is charged to 10kv by 10 1000uf capacitors respectively, and then the switch is closed to the coil through control (that is, image 3 The middle inductance L) discharges, and when the bomb-carrying smoothbore passes through the coil and is about to decelerate to zero, the control switch is turned off, so that ...

The invention discloses a multi-pellet electromagnetic launching device which is mainly composed of a launching pipe and a magnetic resistance type coil gun mechanism which is arranged on the outer wall of the launching pipe, and a driving coil serves as a body of the magnetic resistance type coil gun mechanism. A pellet carrying smoothbore which can bear and launch multiple pellets at the same time is arranged in the launching pipe. The driving coil is arranged on the side wall of the launching pipe, and the pellet carrying smoothbore capable of carrying the pellets in a reciprocating manner is arranged in the launching pipe. The pellet carrying smoothbore which can carry and launch the multiple pellets at the same time is arranged in the launching pipe; a pulse circuit provides an extremely-large pulse current for the driving coil, so that a magnetic field is generated in a ferromagnetic loop; the pellet launching device is attracted to move through the magnetic resistance change of the ferromagnetic loop so that the pellet launching device and the pellets can be accelerated; and finally the pellets fly out of a gun barrel and the pellet launching device stops in the gun barrel, and a traction device is used for drawing the pellet launching device to the original position. The pellets are launched repeatedly multiple times through the pellet carrying smoothbore, so that the limitation that a traditional electromagnetic launching device can only launch one pellet at a time is broken through.
Description
technical field [0001] The invention belongs to the technical field of electromagnetic propulsion, and relates to a multi-projectile electromagnetic bullet-carrying smoothbore. Background technique [0002] The reluctance type coil gun is an electromagnetic propulsion device that uses the reluctance change of the ferromagnetic magnetic circuit of the coil to attract the movement of the iron core to accelerate the iron core projectile. It has some differences from ordinary coil guns. One is that its projectile is a whole piece of ferromagnetic material, and what is accelerated is not a projectile coil or a tubular projectile. The other is that ferromagnetic materials are introduced into the gun system. The performance of the gun has some influence, and the bullet efficiency is higher than that of the hollow coil gun. But the reluctance type coil gun can only fire one projectile at a time. [0003] The reluctance coil gun is composed of a series of helical tube drive coils a...
