Thermal and Electromagnetic Processes on Contacts of Electrodynamic Accelerator

The analysis of processes, running on the contact surfaces of electromagnetic accelerator of a railgun type in the process of armature launch up to high and super - high velocities, has been executed. The review of literary data has been brought. The results of experimental studies of erosion on railgun contacts, which make possible to judge about running processes, has been brought. The numerical simulation of processes, running on the contacts of so called muzzle - fed railgun, has been executed. The cycle of two - dimensional calculations, as well as mediated experimental results, have demonstrated a principle possibility of essential increasing a critical velocity to the account of using the material with anisotropic electric conductivity.
