“…Additionally, the suggested sabot-stopping system enables high-velocity projectile testing while minimizing system perturbations and reducing calibration and characterization time, thereby enhancing testing efficiency. Furthermore, by eliminating the risk of target contamination, it improves the accuracy of the testing process, making it applicable in various domains [46,47]. The proposed system design carries significant implications for the progress of LGG systems, and it is expected to contribute significantly to the advancement of this field.…”

Collisions of space debris and micrometeorites with spacecraft represent an existential hazard for human activities in near-Earth orbits. Currently, guidelines, policies, and best practices are encouraged to help mitigate further propagation of this space debris field from redundant spacecraft and satellites. However, the existing space debris field is an environment that still poses a great threat and requires the design of contingency and fail-safe systems for new spacecraft. In this context, both the monitoring and tracking of space debris impact paths, along with knowledge of spacecraft design features that can withstand such impacts, are essential. Regarding the latter, terrestrial test facilities allow for replicating of space debris collisions in a safe and controlled laboratory environment. In particular, light-gas guns allow launching impactors at speeds in the high-velocity and hypervelocity ranges. The data acquired from these tests can be employed to validate in-orbit observations and structural simulations and to verify spacecraft components’ survivability. Typically, projectiles are launched and protected using a sabot system. This assembly, known as a launch package, is fired towards a sabot-stopping system. The sabot separates from the rest of the launch package, to avoid target contamination, and allows the projectile to travel towards the target through an opening in the assembly. The response and survivability of the sabot-stopping system, along with the transmission of the forces to the light-gas gun structure and prevention of target contamination, is an important design feature of these test apparatuses. In the framework of the development of Malta’s first high-velocity impact facility, particular attention was dedicated to this topic: in this paper, the description of a novel sabot-stopping system is provided. The system described in this research is mechanically decoupled from the interaction with the impact chamber and the light-gas gun pump tube; this solution avoids damage in case of failures and allows easier operations during the pre- and post-test phases.

To protect the spacecraft from hypervelocity impact of the space debris, a new kind of multilayer shield laminated of aluminum layers and CFRP layers was designed and investigated. Three different shields with the same area density were manufactured, including single aluminum alloy layer, single CFRP layer, and multilayer of aluminum/CFRP. The hypervelocity impact experiment was carried, in which the hypervelocity projectile was launched by a two-stage light gas gun. To compare the hypervelocity impact behavior and evaluate the protection ability of the different shields, the area and depth of the projectile pits were analyzed. The experiments results show that the protection effect of the multilayer shield laminated of aluminum/CFRP layers is better than the single aluminum layer or the single CFRP layer, though they are in the same area density.
