摘要: Abstract The formation of high-velocity compact elements shaped charges with a liner combined hemisphere–cylinder shape has been analyzed by numerical simulations two-dimensional axisymmetric problem continuum mechanics. This jet generator contains part hemisphere, truncated sphere or slightly prolate ellipsoid and cut-off in the form cylinder. abstract massive speed characteristics formed depend on changes geometric parameters cumulative liner. Variants an explosive device to ensure gradientless weight from 5 g 15 g at velocities 7.5–10 km/s. simple can be used simulate conditions Earth's single group impact micrometeorites space debris objects rocket technology.
