An impact experiment was performed with a target of relevance to the upcoming DART impact. In this experiment, a collection of stones that is similar to a rubble pile was the target, though it was necessary to hold the stones in place (in this case w

Experiments were performed measuring mass liberated from an Al 2024-T351 target during impacts by a 3.0-cm-diameter aluminum sphere in the range of 4 to 5.77 km/s. The experiments were performed with a large two-stage light gas gun firing into target

Hypervelocity tests with aluminum spheres of 1 and 1.75 inch (2.54 and 4.45 cm)-diameter impacting pumice boulders at 2.1 km/s have been performed at Southwest Research Institute. The results and analysis of the impacts are the main objective of a co

Momentum enhancement refers to the effect of more momentum being transferred to a target than resides in the impactor. This increased momentum transfer is due to crater ejecta leaving the impacted body in the direction opposite to the impactor travel

Momentum enhancement occurs when impactors strike objects at hypervelocities due to the formation of crater ejecta whose departure from the impact body impart more momentum to the impacted body. In previous work the momentum enhancement caused when m

Concrete, sandstone, and, in a previous round of experiments, pumice, were tested under hypervelocity impact at SwRI. Aluminum spheres with diameters of 1 and 1.75 in were shot at a velocity of approximately 2 km/s using a 50-mm conventional powder g

Two NASA missions that will be launched in 2022 have spun renewed interest in hypervelocity impact of rocks and metals. This work focuses on the prediction of the momentum enhancement effect, i.e. the extra momentum acquired by the target due to the

Five nominally identical blast-loading tests were conducted where dynamic deflection data was collected. The dynamic deformation data collected was of the upper surface of a blastloaded hull shape. This data allowed the determination of the initial v
