Abstract
Over time, the weapons have been based on mechanical energy (bows, catapults) and chemical energy (guns, missiles), however, at the moment, more and more weapons are designed using electromagnetic energy (railgun, coilgun). The focus of this paper is to obtain the desired muzzle velocities of a projectile according to the existent current. In the first part of the paper, the railgun and coilgun design are presented along with their most important advantages. Based on these observations, a new design of an electromagnetic launch system is presented. Next, Maxwell interactive software package was used that applies the finite element method (FEM) to analyze and solve 3D electromagnetic field problems in order to analyze the variation of acceleration force, speed in time. All simulation data shows that this design has a great potential, because of the adaptability to different applications.

Nowadays, directed energy weapons (DEWs) are nothing new to mankind
The US Department of Defense (DOD) defines, in Electronic Warfare, a directed-energy weapon as “an umbrella term covering technologies that produce a beam of concentrated electromagnetic energy or atomic or subatomic particles”
DEWs are a part of an electronic attack, along with High Power Microwave, Electromagnetic Pulse and Radio
Summary
Nowadays, directed energy weapons (DEWs) are nothing new to mankind. They were discovered a long time ago when the famous Greek Archimedes allegedly used polished parabolic mirrors to direct sunlight on the sails of Roman ships while defending the city of Syracuse in order to destroy enemy ships with fire. Another system that uses electromagnetic energy to accelerate the projectile is the coilgun system This system is composed of a coil powered by a very high current pulse, of the order of thousands or tens of thousands of amps, in order to create a strong magnetic field using only a fraction of current and avoiding sliding contact, and a projectile. The element is l (length of conductor inside magnetic field) and apparently its value cannot be modified, but if we use more wires (let’s say N turns), like in a coil, we can increase the value of force by N times. The length of each stage is calculated at a dimension of 100 mm These acceleration coils provide the current intensity I and the length l of conductor inside the magnetic field presented in Equation 3. Each coil on stage produces an acceleration force so that the total net force on each stage is multiplied by 2
