Experimental and simulation study of the damage characteristics of spherical balloon under hypervelocity impact

The low-cost self-deployable balloon satellite is one of the application trends of the satellite technology in the future, while the increasing amount of the space debris poses a major threat to the low-Earth spacecraft (include balloon satellite) in orbit. For the survivability analysis of the balloon satellites and the evaluation of the space debris caused by the in-orbit collision, the hypervelocity impact test and the simulation analysis of the spherical balloons are carried out, to obtain the impact damage characteristics of the balloons made of different materials. The damage details and characteristics of the projectile passing through the spherical balloon are preliminarily revealed, to provide a support for the analysis of the fragmentation characteristics of the space debris impacting the balloon satellite.
