Effect of Design Parameter Variation on Force Acting on Projectile of Reluctance Coilgun Type Electromagnetic Launcher

Electromagnetic mass launchers have great potential to replace conventional liquid-based propulsion launch systems. Their design parameters must be accurate to get superior performance. This research work focuses on the variations in the design parameters of reluctance coilgun type electromagnetic launchers and resultant effect on the force acting on the projectile. Variations of geometrical parameters such as projectile's length, diameter, and position, as well as coil's length, and inner and outer diameters along with other design parameters like permeability of projectile, current excitation of the coil, and the number of turns of the projectile are studied and their effects are identified in the form of variation in the force acting on the projectile. This research is based on the electromagnetic effect which is solved using the finite element analysis approach. This research is aimed at enhancing the design of the reluctance coilgun type electromagnetic launcher.
