Embodiment Construction

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] see image 3 , Figure 4 , Figure 5 with Figure 7 , a multi-layer multi-wing type reconnection type electromagnetic launching device, the electromagnetic launching device is a two-layer eight-wing type or a three-layer twelve-wing type; the structure of the two-layer eight-wing type is: the projectile armature 2. The shape consists of two fins on the upper, lower, left and right sides, which are evenly distributed and fixedly connected to a cylinder or a square cylinder. The driving coil 1 is composed of 12 coils with the same number of turns. One drive coil 1 is respectively arranged between each two fins on the lower, left, and right sides and on the outer sides of the two fins, and the distances between the three drive coils and the sides of adjacent fins are the same;

Abstract

The invention relates to a multi-layer multi-wing reconnection type electromagnetic emission device. The multi-layer multi-wing reconnection type electromagnetic emission device is designed as a structure of two layers and eight wings or a structure of three layers and twelve wings. According to the structure of the two layers and the eight wings, the corresponding two wings are evenly and fixedlyconnected to each side of the upper, lower, left and right sides of a cylinder or a square barrel to form a projecting armature, one driving coil is disposed between the two wings of each side, two driving coils are disposed on the outer sides of the two wings, and the distances between the three driving coils in each side and the corresponding adjacent wings are the same. According to the structure of the three layers and the twelve wings, the corresponding three wings are evenly and fixedly connected to each side of the upper, lower, left and right sides of a square barrel to form a projecting armature, two driving coils are disposed between the three wings of each side, two driving coils are disposed on the outer sides of the other two wings except the middle wing, and the distances between the four driving coils in each side and the side surfaces of the corresponding adjacent wings are the same. The multi-layer multi-wing reconnection type electromagnetic emission device has the characteristics of higher local magnetic field utilization ratio and higher emission efficiency.

Description

technical field [0001] The invention belongs to the technical field of electromagnetic propulsion, and relates to a multi-layer and multi-wing reconnection type electromagnetic launching device. Background technique [0002] The reconnection type electromagnetic launch mode was first proposed by Cowen et al. Later, the US Sandia National Laboratory and the US Army Ballistics Laboratory respectively conducted some multi-stage medium-low speed experimental propulsion research and application in the field of kinetic energy weapons. Pie coil design study for single-stage small thrusters in the field of anti-tank armor. Its working principle is to use the "straightening" tendency of the truncated magnetic field lines at the rear of the projectile after recombination to promote the movement of the projectile. In fact, the projectile induces eddy currents in the changing magnetic field and interacts with the magnetic field to generate electromagnetic waves. thrust, thus propelling...
