Title Analysis and Design of Fuze for the shell of Electromagnetic Gun
Abstract
Electromagnetic gun has lots of advantages, such as the large kinetic energy when the projectile is shot because of the high velocity, the uniform acceleration of projectile, shooting with low noise, no smoke, no cartridge, etc. Therefore, the electromagnetic gun is now a hot research topic in military science and technology. Based on this background, this paper is about a warhead fuze, which has timing function, and can remove insurance using magnetic environment. The specific work is as follows: The first part is about the analysis of the electromagnetic railgun firing principle and the characteristics of strong magnetic environment in the chamber, and the calculation of some parameters such as the recoil load; The second part is the design of insurance structure ,the fuze has redundancy safety device, consisting of recoil insurance and magnetic insurance. The final part is the circuit design, including the schematic diagram and the programming on SCM, which can realize the function of the fuze, its correctness is validated with simulation.
