Examples of the use of a rail mass accelerator (railgun) as part of a multifunctional ballistic complex designed to solve problems of high-speed interaction of bodies with obstacles are shown. A description is given of methods for accelerating micro- and macro-scale bodies inside a dielectric container driving through a channel by plasma piston. The results of tests of metal-ceramic coatings formed by laser cladding are presented. It was shown that gas-dynamic effects have a significant influence on the nature of the acceleration of the powder mixture of microparticles. The possibility of using a vacuum chamber to conduct experimental studies of the impact interaction of microparticles with obstacles at low ambient gas pressure has been demonstrated. Keywords: rail mass driver, plasma piston, microparticles, vacuum chamber, ballistic track.
