Embodiment Construction

[0033] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the application and together with the embodiments of the present invention are used to explain the principle of the present invention and are not intended to limit the scope of the present invention.

[0034] The core component in the electromagnetic launch, the track 1 plays the role of conducting current and guiding the armature 2 and the projectile 3 during the launch of the electromagnetic railgun. In order to ensure the good contact of the circuit, the track 1 is in close contact with the armature 2. When launching, it is a high-speed sliding electrical contact process. The current amplitude flowing in the track 1 is very large, and the megaampere current makes the surface temperature of the track 1 very high. Therefore, what the track 1 adopts is a wear-resistant and ablation-resistant...

Abstract

The invention relates to a track, armature of an electromagnetic railgun and the electromagnetic railgun, and belongs to the technical field of electromagnetic railguns. The track, armature of the electromagnetic railgun and the electromagnetic railgun solves the problem that track and armature ablation are serious in the prior art. The guiding face of the track is provided with two curved face protrusions with uniform distribution, and the curved face protrusions are arranged in the axis direction of the track. The curved face protrusions has the same shapes along the section perpendicular tothe axis of the track, and the ratio of the height of each section shape to a chord length is 0.2-0.3. The section shape, section size and position of curved face sunkens of the guiding face of the armature and the curved face protrusions of the guiding face of the track are matched with each other. According to the track, armature of the electromagnetic railgun and the electromagnetic railgun, askin effect and a proximity effect are better utilized, thus current distribution in the track is relatively uniform, the maximum current density is small, the ablation phenomenon on the track surface is alleviated advantageously, and the condition of serious ablation of the track at the corners is avoided.

Description

technical field [0001] The invention relates to the technical field of electromagnetic guns, in particular to an electromagnetic rail gun rail, an armature and an electromagnetic rail gun. Background technique [0002] The working principle of the electromagnetic railgun is made according to the law of electromagnetic induction in physics. The two rails are parallel to each other, and the launch assembly slides along the axis of the rails. The word armature comes from a DC motor. Its function is to transmit the current between the two rails and accept the Lorentz force to push the projectile towards the muzzle for acceleration. , which converts electromagnetic energy into kinetic energy. [0003] Rails and armatures are the core components of electromagnetic launch. During the launch of electromagnetic railguns, rails play the role of conducting current and guiding armatures and projectiles. In order to ensure the good contact of the circuit, the track is in close contact ...
