Whipple shield, a dual-wall system, as well its improved structures, is widely applied to defend the hypervelocity impact of space debris (projectile). This paper reviews studies about mechanism and process protection against impacts using shield. Ground-based experiment numerical simulation for are introduced briefly. Three steps shield discussed in order, including interaction between projectile bumper, movement diffusion cloud, cloud rear plate. Potential improvements performance focusing...
This study investigates how the debris cloud structure and hazardous fragment distribution vary with attack angle by simulating a circular cylinder projectile hypervelocity impinging on thin plate using finite element–smoothed particle hydrodynamics (FE-SPH) adaptive method. Based comparison analysis of experimental simulation results, FE-SPH method was applied to address yaw impact problem, variation law obtained. The screening criterion at is given analyzing formation obtained method,...
The debris cloud generated by the hypervelocity impact (HVI) of orbiting space directly threatens spacecraft. A full understanding damage mechanism rear plate is useful for optimal design protective structures. In this study, yaw a cylindrical aluminum projectile on double-layer simulated FE-SPH adaptive method, and process under analyzed based structure. can be divided into main stage structural response plate. lasts short time basis damage. structure response, continuous deformation...
Shaped charge liner (SCL) has been extensively applied in oil recovery and defense industries. Achieving superior penetration capability through optimizing SCL structures presents a substantial challenge due to intricate rate-dependent processes involving detonation-driven collapse, high-speed jet stretching, penetration. This study introduces an innovative optimization strategy for that employs efficiency as the primary objective function. The combines experimentally validated finite...
