However, those parameters cannot be computed with high fidelity methods such as CFD (Computational Fluid Dynamics) within a reasonable time frame for a full earth re-entry. Thus, correlations are usually used in spacecraft demise codes that use the object-oriented paradigm. However, correlations have often been derived in the 60s for non-destructive re-entry. In this paper, a new methodology to compute drag forces and heat rates for destructive re- entry in the continuum regime, for a large range of geometry is presented. The models are based on CFD computations. The method is applied to complex shape for implementation in the object-oriented code DEBRISK v3.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-226.pdf\" data-type=\"link\" data-id=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/04\/HiSST-2022-226.pdf\">Read full paper here<\/a>><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b> P.
