Flyer acceleration on angara-5-1 installation

The experimental and numerical study of the evolution of the aluminum and steel flyers under flowing of submicrosecond megaampere current pulse with linear current density up to 5 MA/cm through it was carried out. It was obtained that during hundreds nanoseconds the substance of the aluminum flyer near its working surface is in the solid state, and the velocity of the surface can reached ∼ 10 km/s.
