Control of Velocity Projectile on Multistage Coil gun

Coil gun multistage is used to launch a projectile. To increase the velocity of the projectile can be done by adding the number of stages or the number of layers, but it can't control projectile motion. Controlling of the projectile inside the barrel is very important because for regulating the velocity of the projectile when it comes out of the end of the barrel to be as expected. This problem can be solved by a non-uniform multistage coil design. Each coil is twisted separately with the placement between coils coinciding. Multistage coil operation is designed by injecting the current on the coil simultaneously. The injection current setting is difficult because the magnetic force works together so that the coil works to push or slow down the projectile. The genetic algorithm method is used to regulate the current injection to six coils that work together. The method we propose can control projectile motion in the barrel. Uniform multistage coils are used very effectively to regulate projectile motion inside the barrel. The design is shown through multistage coil simulation as a solution to control projectile motion. The Genetic Algorithm Method used in the calculations shows excellent results as expected with a maximum velocity of 31.43 m/s.
