Abstract

In this paper the simulation results of hypersonic accelerator with pulse dynamic biasing system (PDBS) which provide external magnetic field compensation are given. The nearest analog of PDBS shown is Halbach-Array. Using magnetic compensation provides is shown to increase the magnetic field in inter-rail gap of the railgun up to 270% and to increase traction force up to 310%. Besides the magnetic compensation is shown leads to the supressing of magnetic field in outside of railgun system and facilitate EMC problem, at the same time weakening of repulsive force between rails provides the increasing of vitality of the system.
