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

    HighlightsThe formation of high-velocity compact elements of shaped charges has been analyzed.This shaped charges include a liner of a combined hemisphere–cylinder shape.This liner contains a part of a hemisphere and a part in the form of a cylinder.This type of cumulative liner with an explosive device improves velocity of element.This device can be used to simulate the conditions impact of micrometeorites.
