Abstract

Abstract: 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. Highlights: 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.
