Ballistic limit equation for equipment placed behind satellite structure walls
TL;DR: In this article, a triple-plate ballistic limit equation was developed for the case of a Whipple shield configuration or a sandwich panel with honeycomb core placed in front of a backwall.

Vulnerability of spacecraft harnesses to hypervelocity impacts
TL;DR: In this article, the vulnerability of spacecraft harnesses has been assessed during a study performed in framework of a European Space Agency contract, the harnesses consisted of three different space-grade cable types: power cables, screened twisted pair data cables and radio frequency (RF) cables.

Concept for a new light-gas gun type hypervelocity accelerator
Robin Putzar,Frank Schaefer +1 more
TL;DR: In this paper, a two-stage light-gas gun type accelerator was developed at Fraunhofer EMI and the pumping stage was modified to create a single, elongated pressure pulse to act on the projectile.

A stuffed Whipple shield for the Chinese space station
TL;DR: In this article, a new ballistic limit equation (BLE), adopted from the NASA Nextel/Kevlar stuffed Whipple shield equation, was derived from the available experimental data for the three-layer shield.

Four-View Split-Image Fragment Tracking in Hypervelocity Impact Experiments
TL;DR: In this article, the authors used two synchronized high-speed cameras with split images, yielding four views, to record image sequences of the in-flight fragments and analyzed the image sequences by identifying fragments and their trajectories in each view.
