Here the results of comparative analysis of the electrodynamic railgun with increased traction for the acceleration of the large mass bodies are shown. Design of accelerators with multi-blade rotor and coaxial accelerator are illustrated and discussed.enElectrodynamic Railgun, Traction Force, Rotor, Repulsion Force, Torque, Magnetic FieldArticle
