Thermite-for-Demise (T4D): Preliminary assessment on the effects of a thermite charge in plasma wind tunnel experiments [PDF]
, 2023 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
