The historic re-entry of a Delta-II upper stage in 1997 has been re-assessed using a simplified model in DRAMA v3.1 and SAMj. The analysis considers five scenarios covering both object-oriented and component-centric models of the spacecraft, as well as the impact of improvements in material representation since the case was originally executed in 2012.
The trajectories predicted by DRAMA...
The latest data from 2022, shows a record number of satellites were launched and re-entered Earth’s atmosphere compared to previous years. Current projections that account for the growing prevalence of satellite constellations and launch rideshares, suggest that these numbers will continue to rise. This increase in atmospheric re-entry events shows the growing adherence to space debris...
Over the last ten years, the prediction of space debris survivability during their re-entry and the associated prospective ground risk have received an increased interest in the scientific community due to complex multi-physics modelling requirements and crucial industrial applications. Nevertheless, important uncertainties in re-entry physics remain due partially to the lack of data and...
SCARAB Numerical rebuilding Delta II Second Stage re-entry - ATD3 Test Campaign
The Aerothermodynamics Design for Demise (ATD3) Test Case Collaboration Campaign focuses on deepening our understanding and modelling capability of the spacecraft behaviour during the destructive re-entry into the Earth’s atmosphere. This collaboration identifies relevant test cases, and rebuilds them numerically by using different tools. The overall objective is to answer the question: what...
