Jet-charge as an effective tool in the development of spacecraft shields testing against micrometeoroids and man-made debris

This paper introduces a new method using jet-charges for testing shields developed for spacecraft protection against micrometeoroids and man-made debris. A test pattern for obtaining a gradient-free, explosively formed jet is considered. Values of the high-speed projectile velocity, mass and energy are assessed in relation to the angle of the conical liner and the angle of the high-explosive detonation front. Maximum parameters of the high-velocity projectile have been found, and the range of the practical interest has been determined. •A new method using jet-charges for testing spacecraft protection shields is developed.•A test facility for obtaining a gradient-free, explosively formed jet is considered.•Values of the high-speed projectile velocity, mass and energy are assessed.•Maximum parameters of the high-velocity projectile have been found and confirmed experimentally.
