Embodiment Construction

[0038] Such as Figure 1-10 As shown, a new structure of the railgun barrel enables the projectile to obtain rotational acceleration while obtaining linear acceleration in the bore, so that the projectile obtains greater rotational stability after being ejected from the muzzle, and increases the hit rate and damage capability of the projectile. The components of the structure mainly include the first rifled bore 3, the second rifled bore 4, the first electromagnetic guide rail 5, the second electromagnetic guide rail 6, the first insulating strip 9, the second insulating strip 10, the third insulating strip 11, the fourth Insulating strip 12, C-shaped shell stabilizing armature 8, bullet belt shell 7, stainless steel body tube 1, epoxy resin casting pre-tightening body, left front upper lock shaft, right front upper lock shaft, left rear upper lock shaft, right rear upper lock Shaft, Left Front Bottom Lock, Right Front Bottom Lock, Left Rear Bottom Lock, Right Rear Bottom Lock...

Abstract

The invention belongs to the field of electromagnetic launch, and in particular relates to an electromagnetic gun combined with guide rails and rifling segments. Including: rotatable connecting projectile and armature; acceleration guide rail: including first and second electromagnetic guide rails with the same structure opposite to each other; rifled barrel: including first and second rifle bores with the same structure and opposite arrangement, There are inclined riflings with symmetry, the same rotation direction and the same twist in the rifled gun bore. The inner diameter of the electromagnetic guide rail is larger than the inner diameter of the rifled gun barrel. Two double-rifled gun bores and two electromagnetic guide rails are placed vertically alternately; insulation layer: set on the acceleration guide rail The two are isolated from the rifled gun barrel, so that the current only flows in the accelerating guide rail; the guide rail stabilizes the barrel: it is arranged on the outer periphery of the bore tube. The structure of the invention enables the shell to obtain rotational acceleration while obtaining linear acceleration in the bore, so that the shell can obtain greater rotational stability after being ejected from the muzzle, and increase the hit rate and damage ability of the shell.

Description

technical field [0001] The invention belongs to the field of electromagnetic launch, and in particular relates to an electromagnetic gun combined with guide rails and rifling sections. Background technique [0002] An electromagnetic railgun is a weapon that uses electricity as its energy source to fire super-velocity projectiles. The railgun breaks through the limitation of traditional firearms and artillery in terms of launch principle, and changes from chemical energy drive to electric energy drive; this makes the limitation of the exit velocity of traditional artillery be lifted, that is, the electromagnetic railgun can obtain an exit velocity far exceeding that of traditional artillery. When the rail gun is working, the current flows through the guide rail, flows through the armature, returns to the guide rail, forms a strong magnetic field in the flowing area, and then pushes the armature to accelerate. [0003] In recent years, countries headed by the United States h...
