Abstract

The use of thermite to aid spacecraft demise during atmospheric re-entry is investigated in the ESA-TRP SPADEXO project. The Thermite-for-Demise concept was tested in L2K arc-heated wind tunnel facility. In this paper, the design of the samples for the experimental campaign is presented. The SCARAB software was used to tune the heat load on the samples and to predict the test results. A new extension for the representation of exothermic reaction was implemented. A set of numerical and experimental data were compared, confirming good agreement in terms of thermal behaviour of the samples, extra heat provided, and ignition time.
