Electromagnetic launch system based on a Halbach array configuration
Scientific Journal of Silesian University of Technology. Series Transport, 2018 The paper analyses a new configuration of an electromagnetic launch system (EMLS) able to accelerate a 1-kg mass projectile at a muzzle velocity of 3,000 m/s with an acceleration length of 10 m. The analyses consist of a mathematical calculation of the value of acceleration force necessary to achieve the project objectives. Based on these results a new
